This episode of Medicine Matters reviews highlights from the Advisory Committee on Immunization Practices’ (ACIP’s) October 2024 meeting, with new recommendations for pneumococcal, COVID, and meningococcal B (Men B) vaccines, as well as a safety update for maternal RSV vaccination.

Pneumococcal Vaccination and New Lower Age-Based Recommendations 

New age-based recommendation. ACIP has lowered the age for routine vaccination with the pneumococcal conjugate vaccine (PCV) from age 65 down to age 50, but only with PCV. Review of data revealed that more than half of those in the 50- to 64-year-old age group already had a risk indication to receive a PCV dose. In addition, rates of invasive pneumococcal disease peak at younger ages in Black patients compared with White patients. The rate of invasive pneumococcal disease (IPD) among Black adults aged 50 or older exceeds the average rate of IPD for all adults aged 65 or older. The goal of this age-based change is to reduce disease in demographic groups with the highest burden of disease. 

The new expanded age-based recommendation applies only to vaccination with PCV. Conjugate vaccines trigger memory B-cell production and therefore induce greater long-term immunity. New research is now focusing on higher-valent PCV vaccines. Two 24-valent pneumococcal conjugate vaccines and one 31-valent pneumococcal conjugate vaccine are now in advanced stages of development.

Risk-based recommendation. A risk-based recommendation for ages 19 through 49 years still applies to those with certain medical conditions, including diabetes; chronic heart, lung, liver, or kidney disease; and also for those with immunocompromising conditions. Risk-based recommendations are harder to implement particularly because many vaccines are now administered in pharmacies and pharmacists don’t know the patients as well as their physicians do, so it’s harder for them to know who should get the vaccine if the recommendation is based on risk.

COVID-19 Vaccines With Additional Dose Recommendations 

Everyone 6 months or older is recommended to receive a dose of the updated 2024-2025 COVID vaccine. An additional updated COVID vaccine dose is now recommended for everyone aged 65 or older, and for those aged 6 months or older with immunocompromising (moderate or severe) conditions. Review of data revealed that 1 in 6 patients hospitalized with COVID have an immunocompromising condition, and 70% of COVID hospitalizations are in those aged 65 or older. This older age group also has the highest death rates due to COVID-19. We know that vaccination protection wanes with time. Data from previous studies show that additional vaccine doses provide additional protection. Additional doses are now being recommended for those at highest risk.

Timing of additional doses. This second dose is recommended at 6 months after the last updated COVID-19 vaccine dose. However, the additional dose can be given as early as 2 months after the last dose. Those who recently had COVID-19 can wait 3 months before getting an additional vaccine dose. This flexibility allows patients to maximize additional protection by timing additional doses around travel and life events, such as weddings, family get-togethers, or chemotherapy.

Those with immunocompromising conditions may receive more doses. Patients with immunocompromising conditions can receive even more additional doses, if recommended by their physician, under shared clinical decision-making. 

Meningococcal Vaccines

Meningococcal disease is rare but deadly. The disease can progress rapidly. As many as 10%-15% of people with meningococcal infection die, even with appropriate antibiotic therapy. And for those who survive, about 20% suffer long-term sequalae (cognitive deficits, hearing loss, limb amputations).

Aligning Men B vaccine dosing intervals. The new ACIP vote applies only to Men B vaccines, of which there are two: one by GSK (brand name Bexsero), and the other by Wyeth, a Pfizer subsidiary (brand name Trumenba). The two MenB vaccine products are not interchangeable. The same type of MenB vaccine has to be used to complete the series.

The MenB vaccines initially had different dosing schedules and now they don’t. ACIP voted to harmonize and align the dosing schedule for the two different MenB products to mirror recent FDA (Food and Drug Administration) labeling updates. So now the dosing recommendations for both MenB vaccines are the same: either two doses given 6 months apart to healthy adolescents and young adults, or a three-dose series given at zero, 1-2 months, and 6 months for those at high risk or for those who want to optimize rapid protection (for example, if they are starting the series within 6 months of going off to college). But understand that the current recommendation for MenB vaccination for healthy adolescents and young adults is based on shared clinical decision-making, preferably for those aged 16-18.

MenACWY. Two doses of MenACWY are routinely recommended, with the first dose at age 11-12 and a second dose at age 16. The MenACWY vaccines are interchangeable.

Implementation challenges and new pentavalent vaccines. Having to use the same MenB vaccine product for all doses in a patient’s series is difficult. It’s even more difficult when the patient needs both MenACWY and MenB vaccinations. 

Adding to the complexity is a new pentavalent vaccine from Pfizer (brand name Penbraya) that combines MenACWY with the MenB vaccine. And another pentavalent vaccine version by GSK is up for regulatory decision in February 2025.

The work group did say that they plan to take a fresh look at the meningococcal vaccination schedule. Let’s hope it gets simpler, so more to come on that.
 

Respiratory Syncytial Virus (RSV) Vaccines 

Current RSV vaccine recommendations for older adults. RSV vaccine has both age- and risk-based recommendations. Now, everyone aged 75 or older needs a dose of RSV vaccine. Adults aged 60-75 with risk factors for severe RSV are also recommended to receive a dose of RSV vaccine, but not adults without these risk factors. The conditions associated with increased risk for severe RSV disease include lung disease, heart disease, immune compromise, diabetes, obesity with BMI (body mass index) of 40 or higher, neurologic or neuromuscular conditions, chronic kidney disease, liver disorders, and hematologic disorders. Frailty, as well as living in a nursing home or other long-term care facility, are other risk factors for severe RSV disease. Those aged 60-75 without these risk factors are no longer recommended to receive it. 

Three RSV vaccines. We now have three RSV vaccine to choose from. Two are protein subunit vaccines. One is by Pfizer (brand name Abrysvo) that does not contain an adjuvant. The other protein-based RSV vaccine by GSK (brand name Arexvy) does contain an adjuvant. The third RSV vaccine by Moderna (brand name mRESVIA) uses an mRNA platform, and durability of protection is still unclear. However, recent studies now suggest that the RSV protein subunit vaccines confer 36 months of protection rather than only 24 months. 

All three RSV vaccines are licensed for those aged 60 or older. The age indication for GSK’s RSV vaccine, Arexvy, has already been lowered by the FDA to age 50. FDA recently lowered the age approval for Abrysvo to age 18 for those at high risk. However, ACIP has not yet expanded its age recommendations for getting these vaccines. One of the main hesitations is vaccine safety concerns. FDA›s safety update presented to ACIP still suggests an increased risk for Guillain-Barré syndrome with both protein-based RSV vaccines among those aged 65 or older. Fortunately, the risk is rare: less than 10 cases per million vaccinations. 

RSV immunization for infant protection. RSV season starts in October and goes through March. We now have two new ways to protect babies. One is a maternal RSV vaccine, given at 32-36 weeks of pregnancy to moms who will deliver their babies during RSV season. But only Pfizer’s RSV vaccine (brand name Abrysvo, without an adjuvant) can be given during pregnancy. 

A maternal RSV vaccine safety update, presented at ACIP, was reassuring. Abrysvo was not associated with increased risk for preterm birth or small gestational age at birth. 

Nirsevimab, a long-acting monoclonal antibody, can be given to infants. Nirsevimab is indicated for all babies under 8 months of age entering their first RSV season. 

People who received a maternal RSV vaccine during a previous pregnancy are not recommended to receive additional doses during subsequent pregnancies. However, infants born to women who were vaccinated during a prior pregnancy should receive nirsevimab.

New updated COVID vaccines are now available, but who can get them, who should get them, and when? Two updated mRNA COVID vaccines, one by Moderna and the other by Pfizer, have been authorized or approved by the US Food and Drug Administration (FDA) for those aged 6 months or older.

Both vaccines target Omicron’s KP.2 strain of the JN.1 lineage. An updated protein-based version by Novavax, also directed at JN.1, has been authorized, but only for those aged 12 years or older. 

The Centers for Disease Control and Prevention’s (CDC’s) Advisory Committee on Immunization Practices recommends a dose of the 2024-2025 updated COVID vaccine for everyone aged 6 months or older. This includes people who have never been vaccinated against COVID, those who have been vaccinated, as well as people with previous COVID infection. 

The big question is when, and FDA and CDC have set some parameters. For mRNA updated vaccines, patients should wait at least 2 months after their last dose of any COVID vaccine before getting a dose of the updated vaccine.

If the patient has recently had COVID, the wait time is even longer: Patients can wait 3 months after a COVID infection to be vaccinated, but they don’t have to. FDA’s instructions for the Novavax version are not as straightforward. People can get an updated Novavax dose at least 2 months after their last mRNA COVID vaccine dose, or at least 2 months after completing a Novavax two-dose primary series. Those two Novavax doses should be given at least 3 weeks apart. 

Patients can personalize their vaccine plan. They will have the greatest protection in the first few weeks to months after a vaccine, after which antibodies tend to wane. It is a good idea to time vaccination so that protection peaks at big events like weddings and major meetings.

If patients decide to wait, they run the risk of getting a COVID infection. Also keep in mind which variants are circulating and the amount of local activity. Right now, there is a lot of COVID going around, and most of it is related to JN.1, the target of this year’s updated vaccine. If patients decide to wait, they should avoid crowded indoor settings or wear a high-quality mask for some protection. 

Here’s the bottom line: Most people (more than 95%) have some degree of COVID protection from previous infection, vaccination, or both. But if they haven’t recently had COVID infection and didn’t get a dose of last year’s vaccine, they are sitting ducks for getting sick without updated protection. The best way to stay well is to get a dose of the updated vaccine as soon as possible. This is especially true for those in high-risk groups or who are near someone who is high risk. 

Two thirds of COVID hospitalizations are in those aged 65 or older. Hospitalization rates are highest for those aged 75 or older and among infants under 6 months of age. These babies are too young to be vaccinated, but maternal vaccination during pregnancy and breastfeeding can help protect them. 

We’re still seeing racial and ethnic disparities in COVID-related hospitalizations, which are highest among American Indians, Alaska Natives, and Black populations. People with immunocompromising conditions, those with chronic medical conditions, and people living in long-term care facilities are also at greater risk. Unlike last year, additional mRNA doses are not recommended for those aged 65 or older at this time, but that could change.

Since 2020, we’ve come a long way in our fight against COVID, but the battle is still on. In 2023, nearly a million people were hospitalized from COVID. More than 75,000 died. COVID vaccines help protect us from severe disease, hospitalization, and death. 

Let’s face it — we all have booster fatigue, but COVID is now endemic. It’s here to stay, and it’s much safer to update antibody protection with vaccination than with infection. Another benefit of getting vaccinated is that it decreases the chance of getting long COVID. The uptake of last year’s COVID vaccine was abysmal; only about 23% of adults and 14% of children received it.

But this is a new year and a new vaccine. Please make sure your patients understand that the virus has changed a lot. Antibodies we built from previous infection and previous vaccination don’t work as well against these new variants. Antibody levels wane over time, so even if they missed the last few vaccine doses without getting sick, they really should consider getting a dose of this new vaccine. The 2024-2025 updated COVID vaccine is the best way to catch up, update their immunity, and keep them protected. 

Furthermore, we are now entering respiratory virus season, which means we need to think about, recommend, and administer three shots if indicated: COVID, flu, and RSV. Now is the time. Patients can get all three at the same time, in the same visit, if they choose to do so. 

Your recommendation as a physician is powerful. Adults and children who receive a healthcare provider recommendation are more likely to get vaccinated.

People with immunocompromising conditions, those with chronic medical conditions, and people living in long-term care facilities are also at greater risk. Unlike last year, additional mRNA doses are not recommended for those aged 65 or older at this time, but that could change.

Since 2020, we’ve come a long way in our fight against COVID, but the battle is still on. In 2023, nearly a million people were hospitalized from COVID. More than 75,000 died. COVID vaccines help protect us from severe disease, hospitalization, and death. 

Let’s face it — we all have booster fatigue, but COVID is now endemic. It’s here to stay, and it’s much safer to update antibody protection with vaccination than with infection. Another benefit of getting vaccinated is that it decreases the chance of getting long COVID. The uptake of last year’s COVID vaccine was abysmal; only about 23% of adults and 14% of children received it.

But this is a new year and a new vaccine. Please make sure your patients understand that the virus has changed a lot. Antibodies we built from previous infection and previous vaccination don’t work as well against these new variants. Antibody levels wane over time, so even if they missed the last few vaccine doses without getting sick, they really should consider getting a dose of this new vaccine. The 2024-2025 updated COVID vaccine is the best way to catch up, update their immunity, and keep them protected. 

Furthermore, we are now entering respiratory virus season, which means we need to think about, recommend, and administer three shots if indicated: COVID, flu, and RSV. Now is the time. Patients can get all three at the same time, in the same visit, if they choose to do so. 

Your recommendation as a physician is powerful. Adults and children who receive a healthcare provider recommendation are more likely to get vaccinated.

New updated COVID vaccines are now available, but who can get them, who should get them, and when? Two updated mRNA COVID vaccines, one by Moderna and the other by Pfizer, have been authorized or approved by the US Food and Drug Administration (FDA) for those aged 6 months or older.

Both vaccines target Omicron’s KP.2 strain of the JN.1 lineage. An updated protein-based version by Novavax, also directed at JN.1, has been authorized, but only for those aged 12 years or older. 

The Centers for Disease Control and Prevention’s (CDC’s) Advisory Committee on Immunization Practices recommends a dose of the 2024-2025 updated COVID vaccine for everyone aged 6 months or older. This includes people who have never been vaccinated against COVID, those who have been vaccinated, as well as people with previous COVID infection. 

The big question is when, and FDA and CDC have set some parameters. For mRNA updated vaccines, patients should wait at least 2 months after their last dose of any COVID vaccine before getting a dose of the updated vaccine.

If the patient has recently had COVID, the wait time is even longer: Patients can wait 3 months after a COVID infection to be vaccinated, but they don’t have to. FDA’s instructions for the Novavax version are not as straightforward. People can get an updated Novavax dose at least 2 months after their last mRNA COVID vaccine dose, or at least 2 months after completing a Novavax two-dose primary series. Those two Novavax doses should be given at least 3 weeks apart. 

Patients can personalize their vaccine plan. They will have the greatest protection in the first few weeks to months after a vaccine, after which antibodies tend to wane. It is a good idea to time vaccination so that protection peaks at big events like weddings and major meetings.

If patients decide to wait, they run the risk of getting a COVID infection. Also keep in mind which variants are circulating and the amount of local activity. Right now, there is a lot of COVID going around, and most of it is related to JN.1, the target of this year’s updated vaccine. If patients decide to wait, they should avoid crowded indoor settings or wear a high-quality mask for some protection. 

Here’s the bottom line: Most people (more than 95%) have some degree of COVID protection from previous infection, vaccination, or both. But if they haven’t recently had COVID infection and didn’t get a dose of last year’s vaccine, they are sitting ducks for getting sick without updated protection. The best way to stay well is to get a dose of the updated vaccine as soon as possible. This is especially true for those in high-risk groups or who are near someone who is high risk. 

Two thirds of COVID hospitalizations are in those aged 65 or older. Hospitalization rates are highest for those aged 75 or older and among infants under 6 months of age. These babies are too young to be vaccinated, but maternal vaccination during pregnancy and breastfeeding can help protect them. 

We’re still seeing racial and ethnic disparities in COVID-related hospitalizations, which are highest among American Indians, Alaska Natives, and Black populations.

ACIP, the CDC’s Advisory Committee on Immunization Practices, met for 3 days in June. New vaccines and new recommendations for respiratory syncytial virus (RSV), flu, COVID, and a new pneumococcal vaccine were revealed.

RSV Protection

We’ll begin with RSV vaccines for adults aged 60 or older. For this group, shared clinical decision-making is out; it no longer applies. New, more specific recommendations from ACIP for RSV vaccines are both age based and risk based. The age-based recommendation applies to those aged 75 or older, who should receive a single RSV vaccine dose. If they have already received a dose under the old recommendation, they don’t need another one, at least for now.

The risk-based recommendation applies to adults from age 60 up to 75, but only for those with risk factors for severe RSV. These risk factors include lung disease, heart disease, immunocompromise, diabetes, obesity with a BMI of 40 or more, neurologic conditions, neuromuscular conditions, chronic kidney disease, liver disorders, hematologic disorders, frailty, and living in a nursing home or other long-term care facility. Those aged 60-75 with these risk factors should receive the RSV vaccine, and those without them should not receive it. The best time to get the RSV vaccine is late summer, but early fall administration with other adult vaccines is allowed and is acceptable.

Vaccine safety concerns were top of mind as ACIP members began their deliberations. Possible safety concerns for RSV vaccines have been detected for Guillain-Barré syndrome, atrial fibrillation, and idiopathic thrombocytopenic purpura. Safety surveillance updates are still interim and inconclusive. These signals still need further study and clarification. 

Two RSV vaccines have been on the market: one by Pfizer, called Abrysvo, which does not contain an adjuvant; and another one by GSK, called Arexvy, which does contain an adjuvant. With the recent FDA approval of Moderna’s new mRNA RSV vaccine, mRESVIA, there are now three RSV vaccines licensed for those 60 or older. Arexvy is now FDA approved for adults in their 50s. That just happened in early June, but ACIP doesn’t currently recommend it for this fifty-something age group, even for those at high risk for severe RSV disease. This may change with greater clarification of potential vaccine safety concerns.

There is also news about protecting babies from RSV. RSV is the most common cause of hospitalization for infants in the United States, and most hospitalizations for RSV are in healthy, full-term infants. We now have two ways to protect babies: a dose of RSV vaccine given to mom, or a dose of the long-acting monoclonal antibody nirsevimab given to the baby. ACIP clarified that those who received a dose of maternal RSV vaccine during a previous pregnancy are not recommended to receive additional doses during future pregnancies, but infants born to those who were vaccinated for RSV during a prior pregnancy can receive nirsevimab, which is recommended for infants up to 8 months of age during their first RSV season, and for high-risk infants and toddlers aged 8-19 months during their second RSV season.

Last RSV season, supplies of nirsevimab were limited and doses had to be prioritized. No supply problems are anticipated for the upcoming season. A study published in March showed that nirsevimab was 90% effective at preventing RSV-associated hospitalization for infants in their first RSV season.
 

COVID

Here’s what’s new for COVID vaccines. A new-formula COVID vaccine will be ready for fall. ACIP voted unanimously to recommend a dose of the updated 2024-2025 COVID vaccine for everyone aged 6 months or older. This is a universal recommendation, just like the one we have for flu. But understand that even though COVID has waned, it’s still more deadly than flu. Most Americans now have some immunity against COVID, but this immunity wanes with time, and it also wanes as the virus keeps changing. These updated vaccines provide an incremental boost to our immunity for the new formula for fall. FDA has directed manufacturers to use a monovalent JN.1 lineage formula, with a preference for the KP.2 strain.

Older adults (aged 75 or older) and children under 6 months old are hit hardest by COVID. The littlest ones are too young to be vaccinated, but they can get protection from maternal vaccination. The uptake for last year’s COVID vaccine has been disappointing. Only 22.5% of adults and 14% of children received a dose of the updated shot. Focus-group discussions highlight the importance of a physician recommendation. Adults and children who receive a healthcare provider’s recommendation to get the COVID vaccine are more likely to get vaccinated. 
 

Pneumococcal Vaccines

On June 17, 2024, a new pneumococcal vaccine, PCV21, was FDA approved for those aged 18 or older under an accelerated-approval pathway. ACIP voted to keep it simple and recommends PCV21 as an option for adults aged 19 or older who currently have an indication to receive a dose of PCV. This new PCV21 vaccine is indicated for prevention of both invasive pneumococcal disease (IPD) and pneumococcal pneumonia. Its brand name is Capvaxive and it’s made by Merck. IPD includes bacteremia, pneumonia, pneumococcal bacteremia, and meningitis.

There are two basic types of pneumococcal vaccines: polysaccharide vaccines (PPSV), which do not produce memory B cells; and PCV conjugate vaccines, which do trigger memory B-cell production and therefore induce greater long-term immunity. PCV21 covers 11 unique serotypes not in PCV20. This is important because many cases of adult disease are caused by subtypes not covered by other FDA-approved pneumococcal vaccines. PCV21 has greater coverage of the serotypes that cause invasive disease in adults as compared with PCV20. PCV20 covers up to 58% of those strains, while PCV21 covers up to 84% of strains responsible for invasive disease in adults. But there’s one serotype missing in PCV21, which may limit the groups who receive it. PCV21 does not cover serotype 4, a major cause of IPD in certain populations. Adults experiencing homelessness are 100-300 times more likely to develop IPD due to serotype 4. So are adults in Alaska, especially Alaska Natives. They have an 88-fold increase in serotype 4 invasive disease. Serotype 4 is covered by other pneumococcal vaccines, so for these patients, PCV20 is likely a better high-valent conjugate vaccine option than PCV21.
 

Flu Vaccines

What’s new for flu? Everyone aged 6 months or older needs a seasonal flu vaccination every year. That’s not new, but there are two new things coming this fall: (1) The seasonal flu vaccine is going trivalent. FDA has removed the Yamagata flu B strain because it no longer appears to be circulating. (2) ACIP made a special off-label recommendation to boost flu protection for solid organ transplant recipients ages 18-64 who are on immunosuppressive medications. These high-risk patients now have the off-label option of receiving one of the higher-dose flu vaccines, including high-dose and adjuvanted flu vaccines, which are FDA approved only for those 65 or older.

Sandra Fryhofer, MD, highlights updates in the 2024 Advisory Committee on Immunization Practices (ACIP) Adult Immunization Schedule.

The biggest change for 2024 is that you don’t need to wait till January 1, 2024, for these schedules go into effect. Both schedules were published and became available in November 2023 and became effective immediately. They include ACIP recommendations approved by the Centers for Disease Control and Prevention (CDC) director through October 23, 2023.

Subsequent recommendations (before publication of the 2025 schedule) will be added to the addendum, a new Step 5, Section 5 in the schedule. The addendum should make Affordable Care Act (ACA)–compliant insurance plans cover ACIP-recommended immunizations sooner.

This year’s schedule includes more vaccines with new recommendations and new color code keys for the schedule’s vaccine tables. The newest vaccine additions to the 2024 schedule include respiratory syncytial virus (RSV) vaccines, the mpox vaccine (Jynneos), a new MenACWY-MenB combo vaccine (Penbraya), and the new 2023-2024 formulation of the updated COVID vaccine (both mRNA and protein-based adjuvanted versions).

These are listed on the cover page (in alphabetical order) by name, abbreviation, and trade name. Vaccine-specific details can be found in the (Step 3) Notes section, also organized alphabetically.
 

The Tables

Step 1 is Table 1: Vaccinations by Age. Step 2 is Table 2: Vaccinations by Medical Conditions or Other Indications. The table names haven’t changed. However, their color code legends have been adjusted and refined. Also, the legends for the some of the same colors are not the same for both tables.

The order of and conditions covered in the columns on Table 2 have been reorganized.

Even for vaccines whose recommendations have not changed, the color code keys reflecting the recommendations have changed. For this reason, the 2024 version of Table 2 looks very different from the 2023 version. Also, much of the wording on overlays has been removed, which means you have to rely more heavily on the Notes section.

The color brown has been introduced on Table 2 to spotlight groups and conditions that require recurrent revaccination:

• Give Tdap in each and every pregnancy at 27-36 weeks.
• Revaccinate people living with HIV with MenACWY every 5 years.
• Revaccinate those with asplenia and/or complement deficiency with MenACWY every 5 years and MenB every 2-3 years.
• Stem cell transplant recipients need three doses of Hib.

Vaccine order is the same on both tables.

The rows for 2023-2024 formulations of COVID and flu vaccines are at the top of both tables are coded yellow, meaning everyone needs a dose of both vaccines.

Both tables have added a row for RSV vaccines and mpox vaccines.
 

Notes Section

The notes have been edited for clarity and reveal who needs what and when and include special vaccine-specific sections for special circumstances.

COVID vaccines. The COVID vaccine note embraces the updated 2023-2024 formula. Everyone aged 6 months or older needs a dose of the updated COVID vaccine. Specifics of who needs what (and when) depend on what they have already received, as well as their immune status. Detailed recommendations for both mRNA and protein-based adjuvanted versions are included in the notes.

RSV vaccines. The notes also give vital details about RSV vaccines for pregnant people and for older adults. There are two RSV vaccines. Both are preF RSV vaccines. They’re identified by trade names for clarity. Arexvy contains an adjuvant. Abrysvo does not contain an adjuvant. The RSV vaccine note explains that only Abyrsvo (the vaccine without the adjuvant) can be given to pregnant people, only at 32-36 weeks, and only to those whose baby would be born during RSV season.

ACIP recommends a dose of either vaccine for adults aged 60 or older, under shared clinical decision-making (meaning you and your patients have to discuss and decide). The notes link to additional guidance for making that decision.

Mpox vaccines. For the mpox vaccine, all adults in any age group at increased risk of getting mpox should get a two-dose series of the vaccine. The mpox vaccine notes include a list of mpox risk factors.
 

Other Features of the 2024 Adult Immunization Schedule

The schedule has useful links to helpful information:

• Vaccine information statements
• Complete ACIP recommendations
• CDC’s General Best Practice Guidelines for Immunizations.
• VAERS (CDC’s Vaccine Adverse Event Reporting System)

A new “Additional Information” section in the Notes links to:

• Travel vaccination requirements
• Best practices guidelines for vaccinating persons with immunodeficiency
• The National Vaccine Injury Compensation program (for resolving any vaccine injury claims)

The cover page has links to:

• CDC’s vaccine app
• QR code to access the schedule online.

With all these tools literally at your fingertips, there’s no reason not to know which vaccines your patients need and when. The challenge now is making it happen: getting those needed vaccines into arms.

Sandra Fryhofer, MD, highlights updates in the 2024 Advisory Committee on Immunization Practices (ACIP) Adult Immunization Schedule.

The biggest change for 2024 is that you don’t need to wait till January 1, 2024, for these schedules go into effect. Both schedules were published and became available in November 2023 and became effective immediately. They include ACIP recommendations approved by the Centers for Disease Control and Prevention (CDC) director through October 23, 2023.

Subsequent recommendations (before publication of the 2025 schedule) will be added to the addendum, a new Step 5, Section 5 in the schedule. The addendum should make Affordable Care Act (ACA)–compliant insurance plans cover ACIP-recommended immunizations sooner.

This year’s schedule includes more vaccines with new recommendations and new color code keys for the schedule’s vaccine tables. The newest vaccine additions to the 2024 schedule include respiratory syncytial virus (RSV) vaccines, the mpox vaccine (Jynneos), a new MenACWY-MenB combo vaccine (Penbraya), and the new 2023-2024 formulation of the updated COVID vaccine (both mRNA and protein-based adjuvanted versions).

These are listed on the cover page (in alphabetical order) by name, abbreviation, and trade name. Vaccine-specific details can be found in the (Step 3) Notes section, also organized alphabetically.
 

The Tables

Step 1 is Table 1: Vaccinations by Age. Step 2 is Table 2: Vaccinations by Medical Conditions or Other Indications. The table names haven’t changed. However, their color code legends have been adjusted and refined. Also, the legends for the some of the same colors are not the same for both tables.

The order of and conditions covered in the columns on Table 2 have been reorganized.

Even for vaccines whose recommendations have not changed, the color code keys reflecting the recommendations have changed. For this reason, the 2024 version of Table 2 looks very different from the 2023 version. Also, much of the wording on overlays has been removed, which means you have to rely more heavily on the Notes section.

The color brown has been introduced on Table 2 to spotlight groups and conditions that require recurrent revaccination:

• Give Tdap in each and every pregnancy at 27-36 weeks.
• Revaccinate people living with HIV with MenACWY every 5 years.
• Revaccinate those with asplenia and/or complement deficiency with MenACWY every 5 years and MenB every 2-3 years.
• Stem cell transplant recipients need three doses of Hib.

Vaccine order is the same on both tables.

The rows for 2023-2024 formulations of COVID and flu vaccines are at the top of both tables are coded yellow, meaning everyone needs a dose of both vaccines.

Both tables have added a row for RSV vaccines and mpox vaccines.
 

Notes Section

The notes have been edited for clarity and reveal who needs what and when and include special vaccine-specific sections for special circumstances.

COVID vaccines. The COVID vaccine note embraces the updated 2023-2024 formula. Everyone aged 6 months or older needs a dose of the updated COVID vaccine. Specifics of who needs what (and when) depend on what they have already received, as well as their immune status. Detailed recommendations for both mRNA and protein-based adjuvanted versions are included in the notes.

RSV vaccines. The notes also give vital details about RSV vaccines for pregnant people and for older adults. There are two RSV vaccines. Both are preF RSV vaccines. They’re identified by trade names for clarity. Arexvy contains an adjuvant. Abrysvo does not contain an adjuvant. The RSV vaccine note explains that only Abyrsvo (the vaccine without the adjuvant) can be given to pregnant people, only at 32-36 weeks, and only to those whose baby would be born during RSV season.

Hello. I’m Dr Sandra Fryhofer. Welcome to Medicine Matters. The topic is highlights from ACIP’s new adult schedule for 2023, published in the Annals of Internal Medicine, and why this new schedule may be a collector’s item.

It’s a new year, which means a new ACIP adult immunization schedule – a valuable resource collating ACIP’s most up-to-date vaccination recommendations.

Here are this year’s five most important changes:

• COVID vaccines now front and center
• New emphasis on polio vaccination
• Inclusion of some nonvaccine products (such as monoclonal antibody products)
• Pharmacists group has approved the schedule for the first time
• New shared clinical decision-making option for pneumococcal vaccines

The schedule’s organization remains the same. It still has four sections:

• Table 1: vaccinations by age
• Table 2: vaccinations by medical condition and other indications
• The Notes section (alphabetically ordered by vaccine type)
• Appendix listing of vaccine-specific contraindications and precautions

But what’s unique this year is that some of the abbreviations have historical implications. The first change is no big surprise in light of what we’ve gone through in the past few years. COVID vaccines are listed first on the cover page by brand name for those authorized and by company name for those still under US emergency use authorization. They’re also listed first on the graphics and in the notes.

COVID and mRNA and protein-based vaccines have now been assigned official abbreviations based on vaccine platform and valency.

• 1vCOV-mRNA: Comirnaty/Pfizer-BioNTech and Spikevax Moderna COVID-19 vaccines
• 2vCOV-mRNA: Pfizer-BioNTech and Moderna bivalent COVID-19 vaccines
• 1vCOV-aPS: Novavax COVID-19 vaccine

Also remarkable is the absence of COVID viral vector vaccines on the list. However, the viral vector COVID vaccine (which has been available but is not preferred) does have a CDC website link in the Notes section.

A sad but necessary inclusion was triggered by recent polio cases in New York. Polio was believed to be eradicated, and we thought adults no longer needed to be vaccinated against polio. In the new schedule, the polio vaccine is listed on the cover page but is not included in the tables. Current polio vaccination recommendations are now in the Notes section.

Also of historical significance and something that may set a precedent is the inclusion of nonvaccine products. The value of COVID preexposure prophylaxis with products including monoclonal antibodies (such as Evusheld) for people who are moderately or severely immunocompromised is mentioned in the Notes section.

For the first time ever, the schedule has been approved by the American Pharmacists Association, which validates pharmacists as established partners in vaccine administration.
 

Color-code key

One aspect of the schedule that has not changed is the color-code key:

• Yellow: Recommended if the patient meets the age requirement
• Purple: Indicated for those with additional risk factors or another indication
• Blue: Recommended based on shared clinical decision-making
• Orange: Precaution
• Red: Contraindicated or not recommended; the vaccine should not be administered. Overlays on the red more precisely clarify whether a vaccine is really contraindicated or just not recommended. An asterisk on red means vaccinate after pregnancy if indicated.
• Gray: No recommendation or not applicable

Vaccinations by age

Table 1 lists recommended vaccinations by age. There is one major change. COVID vaccines are on the first row of the graphic, with the need for both a primary series and boosters emphasized on the overlay. The notes have hyperlinks to the most up-to-date COVID vaccination recommendations.

Pneumococcal vaccination. Pneumococcal vaccination is routinely recommended starting at age 65. Current recommendations for those not previously vaccinated have not changed since last year. But on Table 1, the bottom half of the row for those 65 or older is now blue (and that’s new). This new color blue means shared clinical decision-making and applies to people who were previously considered fully vaccinated with the now extinct combination of PCV13 and PPSV23. These patients now have the option of getting a dose of PCV20 five years after completing their PCV13-PPSV23 combo series. This option is blue because the decision is up to you and your patient.

Check the notes for more pneumococcal vaccination details. For example, for those partially vaccinated using lower valency vaccines, there’s an option of substituting PCV20 for PPSV23 to broaden and increase durability of protection.

The pneumococcal vaccination recommendation options are complicated. A new pneumococcal vaccination app can help.

Hepatitis B. For adults under age 60, the color code for the hepatitis B vaccine is yellow, meaning it’s indicated for all. For older patients, the color code is purple. If a patient who is age 60 or older wants the hepatitis B vaccine, they can have it even in the absence of additional risk indications.
 

Vaccinations by medical condition or other indications

Other than a few minor word changes on the overlay, the only thing that’s new is the COVID vaccine row.

This table is helpful for matching vaccine recommendations with specific medical conditions, including pregnancy, immunocompromise, HIV (with specifics according to CD4 count), asplenia, complement deficiencies, heart disease, lung disease, alcoholism, chronic liver disease, diabetes, health care personnel, and men who have sex with men.

Use this table to dot the i’s and cross the t’s when it comes to vaccination recommendations. For example, take a look at the pregnancy column. Live virus vaccines, including LAIV, MMR, and varicella, are contraindicated and color-coded red. MMR and varicella also have an asterisk, meaning vaccinate after pregnancy if indicated. HPV vaccines are not live virus vaccines, but the overlay says they are not recommended during pregnancy. The asterisk indicates that you can vaccinate after pregnancy.
 

Vaccine notes

The notes are in alphabetical order, and their organization (routine, special situations, and shared clinical decision-making when indicated) has not changed. They are concise and succinct, but sometimes they’re not enough. That’s why vaccine-specific links to more complete recommendations are so convenient.

Notes for hepatitis B contain nuances on specific dosing for vaccinating patients on dialysis, as well as a reminder that newer hepatitis C vaccines such as Heplisav and PreHevbrio are not recommended during pregnancy due to lack of safety data.

For influenza, everyone 6 months or older still needs yearly flu vaccination with an age- and health-appropriate flu vaccine. But for those aged 65 or older, the notes specify the three vaccine versions now preferred: high-dose, recombinant, or adjuvanted versions. However, if these aren’t available, it’s better to get any flu vaccine than to go without.

Under meningococcal vaccines, the notes for MenACWY and MenB are combined. For MenB, trade names Bexsero and Trumenba are specified because the products are not interchangeable. Booster intervals for those still at risk are different for each vaccine type: every 5 years for MenACWY boosters, and every 2-3 years for boosts of MenB.

The recent polio cases in New York have put polio vaccination in the spotlight. ACIP has now reinstated its Polio Vaccine Work Group. The new schedule lists polio vaccines on the cover page. Current recommendations have been added to the notes section. Routine vaccination for adults is not necessary, at least for now. However, those at increased risk for exposure to polio fall in the special-situation category. For those at increased risk who have completed a polio vaccine series, a single lifetime IPV booster can be given. For those at increased risk who have not completed their polio vaccine series, now would be the time to finish the series.
 

Appendix

The final step in using the new schedule is checking the appendix and its list of vaccine-specific contraindications and precautions.

I hope this review of the new ACIP adult immunization schedule has been helpful. For Medicine Matters, I’m Dr. Sandra Fryhofer.

However, if these aren’t available, it’s better to get any flu vaccine than to go without.

Under meningococcal vaccines, the notes for MenACWY and MenB are combined. For MenB, trade names Bexsero and Trumenba are specified because the products are not interchangeable. Booster intervals for those still at risk are different for each vaccine type: every 5 years for MenACWY boosters, and every 2-3 years for boosts of MenB.

The recent polio cases in New York have put polio vaccination in the spotlight. ACIP has now reinstated its Polio Vaccine Work Group. The new schedule lists polio vaccines on the cover page. Current recommendations have been added to the notes section. Routine vaccination for adults is not necessary, at least for now. However, those at increased risk for exposure to polio fall in the special-situation category. For those at increased risk who have completed a polio vaccine series, a single lifetime IPV booster can be given. For those at increased risk who have not completed their polio vaccine series, now would be the time to finish the series.

The final step in using the new schedule is checking the appendix and its list of vaccine-specific contraindications and precautions.

I hope this review of the new ACIP adult immunization schedule has been helpful. For Medicine Matters, I’m Dr. Sandra Fryhofer.
