More Americans skipping medical care because of cost, survey says
That’s the highest reported number since the pandemic began and a tripling from March to October.
Even 20% of the country’s highest-income households – earning more than $120,000 per year – said they’ve also skipped care. That’s an increase of about seven times for higher-income families since March.
“Americans tend to think there is a group of lower-income people, and they have worse health care than the rest of us, and the rest of us, we’re okay,” Tim Lash, chief strategy officer for West Health, a nonprofit focused on lowering health care costs, told CBS News.
“What we are seeing now in this survey is this group of people who are identifying themselves as struggling with health care costs is growing,” he said.
As part of the 2021 Healthcare in America Report, researchers surveyed more than 6,000 people in September and October about their concerns and experiences with affording health care and treatment. About half of respondents said health care in America has gotten worse because of the pandemic, and more than half said they’re more worried about medical costs than before.
What’s more, many Americans put off routine doctor visits at the beginning of the pandemic, and now that they’re beginning to schedule appointments again, they’re facing major costs, the survey found. Some expenses have increased in the past year, including prescription medications.
The rising costs have led many people to skip care or treatment, which can have major consequences. About 1 in 20 adults said they know a friend or family member who died during the past year because they couldn’t afford medical care, the survey found. And about 20% of adults said they or someone in their household had a health issue that grew worse after postponing care because of price.
About 23% of survey respondents said that paying for health care represents a major financial burden, which increases to a third of respondents who earn less than $48,000 per year. Out-of-pocket costs such as deductibles and insurance premiums have increased, which have taken up larger portions of people’s budgets.
“We often overlook the side effect of costs, and it’s quite toxic – there is a financial toxicity that exists in health care,” Mr. Lash said. “We know when you skip treatment, that can have an impact on mortality.”

Major COVID-19 case growth expected in coming weeks
by the PolicyLab at Children’s Hospital of Philadelphia.
Large metropolitan areas, especially those in the Northeast, are already seeing a major increase in cases following Thanksgiving, and that trend is expected to continue.
“Why? Simply stated, the large amount of Thanksgiving travel and gatherings undermined the nation’s pandemic footing and has elevated disease burden in areas of the country that were fortunate to have lower case rates before the holidays,” the forecasters wrote.
Case numbers in New York City are expected to double throughout December, the forecasters said. Similar growth could happen across Boston, Philadelphia, and Baltimore.
Overall, COVID-19 cases, hospitalizations, and deaths are rising across the United States but remain below levels seen during the summer and last winter’s surges, according to the New York Times. The increase is still being driven by the Delta variant, though it remains unclear how the Omicron variant, which has been detected in 27 states, could affect the trends in the coming weeks.
During the past week, the United States has reported an average of more than 120,000 new cases each day, the newspaper reported, which is an increase of 38% from two weeks ago.
The daily average of COVID-19 hospitalizations is around 64,000, which marks an increase of 22% from two weeks ago. More than 1,300 deaths are being reported each day, which is up 26%.
Numerous states are reporting double the cases from two weeks ago, stretching across the country from states in the Northeast such as Connecticut and Rhode Island to southern states such as North Carolina and Texas and western states such as California.
The Great Lakes region and the Northeast are seeing some of the most severe increases, the newspaper reported. New Hampshire leads the United States in recent cases per capita, and Maine has reported more cases in the past week than in any other seven-day period during the pandemic.
Michigan has the country’s highest hospitalization rate, and federal medical teams have been sent to the state to help with the surge in patients, according to The Detroit News. Michigan’s top public health officials described the surge as a “critical” and “deeply concerning” situation on Dec. 10, and they requested 200 more ventilators from the Strategic National Stockpile.
Indiana, Maine, and New York have also requested aid from the National Guard, according to USA Today. Health officials in those states urged residents to get vaccines or booster shots and wear masks in indoor public settings.
The Omicron variant can evade some vaccine protection, but booster shots can increase efficacy and offer more coverage, Anthony Fauci, MD, director of the National Institute of Allergy and Infectious Diseases, said Dec. 12.
“If you want to be optimally protected, absolutely get a booster,” he said on ABC’s “This Week.”
In addition, New York Gov. Kathy Hochul has announced a statewide mask mandate, which will take effect Dec. 13. Masks will be required in all indoor public spaces and businesses, unless the location implements a vaccine requirement instead, the news outlet reported.

Omicron may require fourth vaccine dose, Pfizer says
, Pfizer officials said on Dec. 8.
The standard two doses may be less effective against the variant, the company announced earlier in the day, and a booster dose increases neutralizing antibodies.
But the timeline might need to be moved up for a fourth dose. Previously, Pfizer CEO Albert Bourla, PhD, said another dose might be needed about a year after a third shot. Now the company’s scientists believe that a fourth shot, which targets the Omicron variant, could be required sooner.
“With Omicron, we need to wait and see because we have very little information. We may need it faster,” Dr. Bourla said on CNBC’s Squawk Box.
“But for right now, the most important thing is that we have winter in front of us,” he said. “From a healthcare perspective, it is important to understand that we need to be well-protected to go through the winter.”
A third dose should provide protection throughout the winter, Dr. Bourla said. That may buy time until the early spring to develop new shots that target Omicron, which Pfizer could have ready by March, according to Bloomberg News.
As of the afternoon of Dec. 8, 43 people in 19 states had tested positive for the Omicron variant, according to The Associated Press. More than 75% had been vaccinated, and a third had had booster shots. About a third had traveled internationally.
Nearly all of them have had mild symptoms so far, the AP reported, with the most common symptoms being a cough, congestion, and fatigue. One person has been hospitalized, but no deaths have been reported so far.
The CDC is still trying to determine how the Omicron variant may affect the course of the pandemic and whether the strain is more contagious or causes more severe disease.
“What we generally know is the more mutations a variant has, the higher level you need your immunity to be,” Rochelle Walensky, MD, director of the CDC, told the AP.
“We want to make sure we bolster everybody’s immunity,” she said. “And that’s really what motivated the decision to expand our guidance [on boosters for all adults].”
The Omicron variant has been reported in 57 countries so far, World Health Organization officials reported Dec. 8, and they expect that number to continue growing.
“Certain features of Omicron, including its global spread and large number of mutations, suggest it could have a major impact on the course of the pandemic. Exactly what that impact will be is still difficult to know,” Tedros Adhanom Ghebreyesus, PhD, the World Health Organization’s director-general, said during a media briefing.
Several studies suggest that Omicron leads to a rapid increase in transmission, he said, though scientists are still trying to understand whether it can “outcompete Delta.” Data from South Africa also suggests a higher risk of reinfection with Omicron, though it appears to cause milder disease than Delta, he noted.
“Even though we still need answers to some crucial questions, we are not defenseless against Omicron or Delta,” he said. “The steps countries take today, and in the coming days and weeks, will determine how Omicron unfolds.”

Could Viagra help prevent Alzheimer’s?
published in the journal Nature Aging.
Patients who used the drug sildenafil, the generic name for Viagra, were 69% less likely to develop the disease than were nonusers.
“Sildenafil, which has been shown to significantly improve cognition and memory in preclinical models, presented as the best drug candidate,” Feixiong Cheng, PhD, the lead study author in the Cleveland Clinic’s Genomic Medicine Institute, said in a statement.
“Notably, we found that sildenafil use reduced the likelihood of Alzheimer’s in individuals with coronary artery disease, hypertension, and type 2 diabetes, all of which are comorbidities significantly associated with risk of the disease, as well as in those without,” he said.
Alzheimer’s, which is the most common form of age-related dementia, affects hundreds of millions of people worldwide. The disease is expected to affect nearly 14 million Americans by 2050. There is no approved treatment for it.
Dr. Cheng and colleagues at the Cleveland Clinic used a large gene-mapping network to analyze whether more than 1,600 Food and Drug Administration–approved drugs could work against Alzheimer’s. They gave higher scores to drugs that target both amyloid and tau proteins in the brain, which are two hallmarks of the disease. Sildenafil appeared at the top of the list.
Then the researchers used a database of health insurance claims for more than 7 million people in the U.S. to understand the relationship between sildenafil and Alzheimer’s disease outcomes. They compared sildenafil users to nonusers and found that those who used the drug were 69% less likely to have the neurodegenerative disease, even after 6 years of follow-up.
After that, the research team came up with a lab model that showed the sildenafil increased brain cell growth and targeted tau proteins. The lab model could indicate how the drug influences disease-related brain changes.
But Dr. Cheng cautioned against drawing strong conclusions. The study doesn’t demonstrate a causal relationship between sildenafil and Alzheimer’s disease. Researchers will need to conduct clinical trials with a placebo control to see how well the drug works.
Other researchers said the findings offer a new avenue for research but don’t yet provide solid answers.
“Being able to repurpose a drug already licensed for health conditions could help speed up the drug discovery process and bring about life-changing dementia treatments sooner,” Susan Kohlhaas, PhD, director of research at Alzheimer’s Research UK, told the Science Media Centre.
“Importantly, this research doesn’t prove that sildenafil is responsible for reducing dementia risk, or that it slows or stops the disease,” she continued. “If you want to discuss any treatments you are receiving, the first port of call is to speak to your doctor.”
And doctors won’t likely recommend it as a treatment just yet either.
“While these data are interesting scientifically, based on this study, I would not rush out to start taking sildenafil as a prevention for Alzheimer’s disease,” Tara Spires-Jones, PhD, deputy director of the Centre for Discovery Brain Sciences at the University of Edinburgh, told the Science Media Centre.

COVID-19 antibody drug likely works against Omicron, companies say
The companies said Dec. 2 that they tested the drug, called sotrovimab, against individual mutations found in the Omicron variant, according to The Wall Street Journal. The preliminary findings haven’t yet been peer-reviewed, and the drug will need to be tested against the whole spike protein on the virus to confirm results.
GlaxoSmithKline and Vir have previously tested sotrovimab against mutations on other variants, the newspaper reported. When the Omicron variant was identified, the companies looked at earlier research to find the tests they had done against mutations that are also found in Omicron.
Sotrovimab targets a spot on the spike protein that is found in other coronaviruses and is thought to be less likely to mutate, according to the newspaper. Omicron has at least two mutations that overlap with the drug’s target site, but researchers at the companies don’t think the mutations will affect the treatment’s ability to bind to the spike protein.
GlaxoSmithKline expects to see results from testing the drug against the full mutated spike protein in the next 2 to 3 weeks, the Journal reported.
Sotrovimab has been authorized in about a dozen countries, including the United States, which paid about $1 billion for hundreds of thousands of doses.
Other companies have also been testing their antibody treatments against the Omicron variant.
Regeneron announced Nov. 30 that its drug could be less effective, and it said further analyses will determine how much less effective by using the actual Omicron genetic sequence, according to Reuters.
Outside scientists have also said the antibody drug from Eli Lilly & Co. isn’t as effective against Omicron. The company told Reuters that it is still testing the treatment against the variant.
Another experimental antibody therapy developed by Adagio Therapeutics appears to work well against the new variant, the Journal reported, but the treatment is in late-stage clinical trials and isn’t yet authorized.
Antiviral drugs could also help prevent hospitalization and may be less vulnerable to new variants because they target a different part of the virus, the newspaper reported. Merck and Pfizer have developed antiviral pills, which still require FDA approval.
In addition, Gilead believes its approved IV therapy, called remdesivir, will continue to be effective against the variant, Reuters reported.
The FDA said Nov. 30 that it is looking at the effect that authorized COVID-19 vaccines can have on Omicron and expects to have more information in coming weeks, Reuters reported.

The companies said Dec. 2 that they tested the drug, called sotrovimab, against individual mutations found in the Omicron variant, according to The Wall Street Journal. The preliminary findings haven’t yet been peer-reviewed, and the drug will need to be tested against the whole spike protein on the virus to confirm results.
GlaxoSmithKline and Vir have previously tested sotrovimab against mutations on other variants, the newspaper reported. When the Omicron variant was identified, the companies looked at earlier research to find the tests they had done against mutations that are also found in Omicron.

Moderna warns of material drop in vaccine efficacy against Omicron
“There is no world, I think, where [the effectiveness] is the same level … we had with Delta,” Stephane Bancel told the Financial Times .
“I think it’s going to be a material drop,” he said. “I just don’t know how much, because we need to wait for the data. But all the scientists I’ve talked to … are like, ‘This is not going to be good.’”
Vaccine companies are now studying whether the new Omicron variant could evade the current shots. Some data is expected in about 2 weeks.
Mr. Bancel said that if a new vaccine is needed, it could take several months to produce at scale. He estimated that Moderna could make billions of vaccine doses in 2022.
“[Moderna] and Pfizer cannot get a billion doses next week. The math doesn’t work,” he said. “But could we get the billion doses out by the summer? Sure.”
The news caused some panic on Nov. 30, prompting financial markets to fall sharply, according to Reuters. But the markets recovered after European officials gave a more reassuring outlook.
“Even if the new variant becomes more widespread, the vaccines we have will continue to provide protection,” Emer Cooke, executive director of the European Medicines Agency, told the European Parliament.
Mr. Cooke said the agency could approve new vaccines that target the Omicron variant within 3 to 4 months, if needed. Moderna and Pfizer have announced they are beginning to tailor a shot to address the Omicron variant in case the data shows they are necessary.
Also on Nov. 30, the European Centre for Disease Prevention and Control announced that 42 Omicron cases had been identified in 10 European Union countries, according to Reuters.
The cases were mild or had no symptoms, although they were found in younger people who may have mild or no symptoms anyway.
“For the assessment of whether [Omicron] escapes immunity, we still have to wait until investigations in the laboratories with [blood samples] from people who have recovered have been carried out,” Andrea Ammon, MD, chair of the agency, said during an online conference.
The University of Oxford, which developed a COVID-19 vaccine with AstraZeneca, said Nov. 30 that there’s no evidence that vaccines won’t prevent severe disease from the Omicron variant, according to Reuters.
“Despite the appearance of new variants over the past year, vaccines have continued to provide very high levels of protection against severe disease and there is no evidence so far that Omicron is any different,” the university said in a statement. “However, we have the necessary tools and processes in place for rapid development of an updated COVID-19 vaccine if it should be necessary.”

Pfizer COVID vaccine is 100% effective in adolescents: Study
Pfizer announced on Nov. 22 that its COVID-19 vaccine provided long-term protection against the virus in a late-stage clinical trial among adolescents ages 12-15.
A two-dose series was 100% effective against COVID-19, which was measured between 7 days and 4 months after the second dose.
“As the global health community works to increase the number of vaccinated people around the world, these additional data provide further confidence in our vaccine safety and effectiveness profile in adolescents,” Albert Bourla, PhD, chairman and CEO of Pfizer, said in a statement.
The clinical trial researchers found no serious safety concerns while following patients for 6 months. The adverse events were consistent with other clinical safety data for the vaccine, the company said.
Pfizer will incorporate the data into its submissions for full regulatory approval of the vaccine for ages 12-15 in the United States and worldwide.
The company will request clearance for a 30-mcg dose of the vaccines for ages 12 and older. The shot received FDA emergency use authorization for ages 12-15 in May and full approval for ages 16 and older in August.
The study included 2,228 clinical trial participants who were monitored between November 2020 and September 2021. There were 30 confirmed symptomatic cases of COVID-19 in the placebo group that didn’t receive the vaccine and 0 COVID-19 cases among the vaccinated group.
The efficacy was consistently high across gender, race, ethnicity, and health conditions, the company said.
“This is especially important as we see rates of COVID-19 climbing in this age group in some regions, while vaccine uptake has slowed,” Mr. Bourla said. “We look forward to sharing these data with the FDA and other regulators.”

Mask-wearing cuts new COVID-19 cases by 53%, study says
Social distancing and handwashing were also effective at lowering the number of cases, but wearing masks was the most effective tool against the coronavirus.
“Personal and social measures, including handwashing, mask wearing, and physical distancing are effective at reducing the incidence of COVID-19,” the study authors wrote.
The research team, which included public health and infectious disease specialists in Australia, China, and the U.K., evaluated 72 studies of COVID-19 precautions during the pandemic. They later looked at eight studies that focused on handwashing, mask wearing, and physical distancing.
Among six studies that looked at mask wearing, the researchers found a 53% reduction in COVID-19 cases. In the broader analysis with additional studies, wearing a mask reduced coronavirus transmission, cases, and deaths.
In one study across 200 countries, mandatory mask wearing resulted in nearly 46% fewer negative outcomes from COVID-19. In another study in the U.S., coronavirus transmission was reduced 29% in states where masks were mandatory.
But the research team couldn’t analyze the impact of the type of face mask used, the frequency of mask wearing, or the overall compliance with wearing face masks.
Among five studies that looked at physical distancing, the researchers found a 25% reduction in the rate of COVID-19. A study in the U.S. showed a 12% decrease in coronavirus transmission, while another study in Iran reported a reduction in COVID-19 mortality.
Handwashing interventions also suggested a substantial reduction of COVID-19 cases up to 53%, the researchers wrote. But in adjusted models, the results weren’t statistically significant due to the small number of studies included.
Other studies found significant decreases related to other public health measures, such as quarantines, broad lockdowns, border closures, school closures, business closures, and travel restrictions. Still, the research team couldn’t analyze the overall effectiveness of these measures due to the different ways the studies were conducted.
The study lines up with other research conducted so far during the pandemic, the research team wrote, which indicates that wearing masks and physical distancing can reduce transmission, cases, and deaths.
That said, more studies are needed, particularly now that vaccinations are available and contagious coronavirus variants have become prevalent.
“Further research is needed to assess the effectiveness of public health measures after adequate vaccination coverage has been achieved,” they wrote.
“It is likely that further control of the COVID-19 pandemic depends not only on high vaccination coverage and its effectiveness but also on ongoing adherence to effective and sustainable public health measures,” they concluded.

With COVID-19 prevalent in deer, experts urge precautions
With deer hunting season underway or starting in states across the United States, people should wear a mask and gloves when handling deer to prevent coronavirus transmission, experts say.
A recent study by researchers at Penn State University found that more than 80% of the deer sampled during last year’s hunting season in counties across Iowa tested positive for COVID-19. Overall, a third of the deer sampled between September 2020 and January 2021 tested positive.
“The findings suggest that white-tailed deer may be a reservoir for the virus to continually circulate and raise concerns about the emergence of new strains that may prove a threat to wildlife and, possibly, to humans,” the researchers said in a statement.
The deer were likely infected due to “multiple human-to-deer spillover events and deer-to-deer transmission,” they noted.
Studies haven’t shown whether deer have infected humans, but public health experts are recommending that hunters and deer handlers consider possible transmission avenues, The Plain Dealer, a Cleveland newspaper, reported.
To limit deer-to-deer transmission, homeowners and hunters should avoid concentrating deer at backyard feeders or in hunting situations, according to the Ohio Department of Natural Resources Division of Wildlife. The department also urged people to not allow contact between wildlife and domestic animals, including pets and hunting dogs.
Eating venison shouldn’t be a concern if people cook the meat thoroughly, the newspaper reported. Until more is known, people should wear a mask and gloves when handling deer.
In the study, Penn State researchers examined 283 deer between December 2020 and January 2021. They took samples from lymph nodes in the head and neck as part of Iowa’s chronic wasting disease surveillance program.
“This is the first direct evidence of SARS-CoV-2 virus in any free-living species, and our findings have important implications for the ecology and long-term persistence of the virus,” Suresh Kuchipudi, PhD, associate director of the Animal Diagnostics Laboratory at Penn State, said in the statement.
“These include spillover to other free-living or captive animals and potential spillback to human hosts,” he said. “Of course, this highlights that many urgent steps are needed to monitor the spread of the virus in deer and prevent spillback to humans.”
The research team sequenced genomes from all the positive samples and identified 12 coronavirus lineages. The prominent ones corresponded to the same lineages found in humans at the time.
The U.S. Department of Agriculture has also inspected 480 samples this year from white-tailed deer in Illinois, Michigan, New York, and Pennsylvania. Researchers detected virus antibodies in 33% of samples, according to a statement from the department. The department has confirmed the virus in deer in Ohio as well.
Health officials have recommended that hunters also take precautions while around other people by getting vaccinated and wearing a mask, according to WMTV in Wisconsin.
“If someone comes to deer camp and they have COVID and other folks aren’t vaccinated, in that enclosed space with the laughing and good times that are had, the likelihood that those other hunters would be infected is pretty high,” Jeff Pothof, MD, an emergency medicine doctor at UW Health, told the news outlet.
“I think the biggest risk to deer hunters is going to be other hunters, not so much the deer,” he said.

“This is the first direct evidence of SARS-CoV-2 virus in any free-living species, and our findings have important implications for the ecology and long-term persistence of the virus,” Suresh Kuchipudi, PhD, associate director of the Animal Diagnostics Laboratory at Penn State, said in the statement.
“These include spillover to other free-living or captive animals and potential spillback to human hosts,” he said. “Of course, this highlights that many urgent steps are needed to monitor the spread of the virus in deer and prevent spillback to humans.”
The research team sequenced genomes from all the positive samples and identified 12 coronavirus lineages. The prominent ones corresponded to the same lineages found in humans at the time.
The U.S. Department of Agriculture has also inspected 480 samples this year from white-tailed deer in Illinois, Michigan, New York, and Pennsylvania. Researchers detected virus antibodies in 33% of samples, according to a statement from the department. The department has confirmed the virus in deer in Ohio as well.
Health officials have recommended that hunters also take precautions while around other people by getting vaccinated and wearing a mask, according to WMTV in Wisconsin.
“If someone comes to deer camp and they have COVID and other folks aren’t vaccinated, in that enclosed space with the laughing and good times that are had, the likelihood that those other hunters would be infected is pretty high,” Jeff Pothof, MD, an emergency medicine doctor at UW Health, told the news outlet.
“I think the biggest risk to deer hunters is going to be other hunters, not so much the deer,” he said.

COVID-19 vaccine mandates are working, public health experts say
Some organizations have reported vaccination rates that jumped from less than 50% to more than 90%, according to ABC News. Workplace mandates have especially encouraged employees who were on the fence to get a shot.
“In general, vaccine mandates work,” James Colgrove, a public health professor at Columbia University’s Mailman School of Public Health, told ABC News.
For decades, the United States has monitored the effectiveness of vaccine mandates in schools, he noted, which have successfully required shots against measles, mumps, and other illnesses that used to be widespread. Certain employees, such as hospital workers, must take vaccines for their jobs, he said, and those requirements have also been effective over the years.
“The more normalized it becomes, the more people [know] someone else who is vaccinated, the more people will comply,” he said. “With any vaccine, the longer it’s been around, the more people get with it.”
With the widespread and contagious nature of COVID-19, workplaces have been forced to consider vaccine mandates to protect their employees and prevent worker shortages, Dr. Colgrove said.
Some companies began to issue vaccine rules this summer as the Delta variant caused a jump in cases, hospitalizations, and deaths. Major companies, including Google, Tyson Foods, United Airlines, and the Walt Disney Company, required in-person employees to get a shot. So far, the results from those mandates have been strong, ABC News reported.
For instance, Tyson announced a mandate in August, when less than half of its 140,000 employees were vaccinated. When the deadline came at the end of October, more than 60,000 additional employees had been vaccinated, and the vaccination rate was 96%.
“Has this made a difference in the health and safety of our team members? Absolutely. We’ve seen a significant decline in the number of active cases companywide,” Donnie King, CEO and president of Tyson Foods, said in a statement.
United Airlines has also shared that 99.7% of its 67,000 employees are vaccinated. Within 48 hours of announcing its mandate, the number of unvaccinated staffers fell from 593 to 320 people, ABC News reported.
Vaccine mandates appear to be working in the public sector as well. State health department officials in Washington told ABC News that the percentage of public employees who were vaccinated jumped from 49% in September to 96% by the vaccine mandate deadline in October.
Vaccination rates have also increased in New York City, where some employees in the fire, police, and sanitation departments protested the mandate. By the deadline, vaccination rates shifted from less than 75% to 82% in the fire department, 86% in the police department, and 91% of EMS personnel, ABC News reported.
Overall, vaccine mandates tend to reach groups who aren’t completely against the vaccine, medical experts told the news outlet. A small percentage of the population truly opposes the shot, and in most cases, unvaccinated people are on the fence or haven’t seen good enough messaging for it.
“When you look at vaccine resistance, the people who are the most opposed often make a very large amount of noise that is at odds with the actual numbers who are against vaccination,” Dr. Colgrove said.
