Many countries have “a long way to go” toward meeting the World Health Organization’s target for human papilloma virus (HPV) vaccination, according to researchers.

The WHO’s goal is to have HPV vaccines delivered to 90% of all adolescent girls by 2030, part of the organization’s larger goal to “eliminate” cervical cancer, or reduce the annual incidence of cervical cancer to below 4 cases per 100,000 people globally.

Laia Bruni, MD, PhD, of Catalan Institute of Oncology in Barcelona, and colleagues outlined the progress made thus far toward reaching the WHO’s goals in an article published in Preventive Medicine.

The authors noted that cervical cancer caused by HPV is a “major public health problem, especially in low- and middle-income countries (LMIC).”

However, vaccines against HPV have been available since 2006 and have been recommended by the WHO since 2009.

HPV vaccines have been introduced into many national immunization schedules. Among the 194 WHO member states, 107 (55%) had introduced HPV vaccination as of June 2020, according to estimates from the WHO and the United Nations International Children’s Emergency Fund (UNICEF).

Still, vaccine introduction and coverages are suboptimal, according to several studies and international agencies.

In their article, Dr. Bruni and colleagues describe the mid-2020 status of HPV vaccine introduction, based on WHO/UNICEF estimates of national HPV immunization coverage from 2010 to 2019.
 

HPV vaccination by region

The Americas and Europe are by far the WHO regions with the highest rates of HPV vaccination, with 85% and 77% of their countries, respectively, having already introduced HPV vaccination, either partially or nationwide.

In 2019, a record number of introductions, 16, were reported, mostly in LMICs where access has been limited. In prior years, the average had been a relatively steady 7-8 introductions per year.

The percentage of high-income countries (HICs) that have introduced HPV vaccination exceeds 80%. LMICs started introducing HPV vaccination later and at a slower pace, compared with HICs. By the end of 2019, only 41% of LMICs had introduced vaccination. However, of the new introductions in 2019, 87% were in LMICs.

In 2019, the average performance coverage for HPV vaccination programs in 99 countries (both HICs and LMICs) was around 67% for the first vaccine dose and 53% for the final dose.

Median performance coverage was higher in LMICs than in HICs for the first dose (80% and 72%, respectively), but mean dropout rates were higher in LMICs than in HICs (18% and 11%, respectively).

Coverage of more than 90% was achieved for the last dose in only five countries (6%). Twenty-two countries (21%) achieved coverages of 75% or higher, while 35 countries (40%) had final dose coverages of 50% or less.

Global coverage of the final HPV vaccine dose (weighted by population size) was estimated at 15%. According to the authors, that low percentage can be explained by the fact that many of the most populous countries have either not yet introduced HPV vaccination or have low performance.

The countries with highest cervical cancer burden have had limited secondary prevention and have been less likely to provide access to vaccination, the authors noted. However, this trend appears to be reversing, with 14 new LMICs providing HPV vaccination in 2019.
 

 

 

HPV vaccination by sex

By 2019, almost a third of the 107 HPV vaccination programs (n = 33) were “gender neutral,” with girls and boys receiving HPV vaccines. Generally, LMICs targeted younger girls (9-10 years) compared with HICs (11-13 years).

Dr. Bruni and colleagues estimated that 15% of girls and 4% of boys were vaccinated globally with the full course of vaccine. At least one dose was received by 20% of girls and 5% of boys.

From 2010 to 2019, HPV vaccination rates in HICs rose from 42% in girls and 0% in boys to 88% and 44%, respectively. In LMICs, over the same period, rates rose from 4% in girls and 0% in boys to 40% and 5%, respectively.
 

Obstacles and the path forward

The COVID-19 pandemic has halted HPV vaccine delivery in the majority of countries, Dr. Bruni and colleagues noted. About 70 countries had reported program interruptions by August 2020, and delays to HPV vaccine introductions were anticipated for other countries.

An economic downturn could have further far-reaching effects on plans to introduce HPV vaccines, Dr. Bruni and colleagues observed.

While meeting the 2030 target will be challenging, the authors noted that, in every geographic area, some programs are meeting the 90% target.

“HPV national programs should aim to get 90+% of girls vaccinated before the age of 15,” Dr. Bruni said in an interview. “This is a feasible goal, and some countries have succeeded, such as Norway and Rwanda. Average performance, however, is around 55%, and that shows that it is not an easy task.”

Dr. Bruni underscored the four main actions that should be taken to achieve 90% coverage of HPV vaccination, as outlined in the WHO cervical cancer elimination strategy:

  • Secure sufficient and affordable HPV vaccines.
  • Increase the quality and coverage of vaccination.
  • Improve communication and social mobilization.
  • Innovate to improve efficiency of vaccine delivery.

“Addressing vaccine hesitancy adequately is one of the biggest challenges we face, especially for the HPV vaccine,” Dr. Bruni said. “As the WHO document states, understanding social, cultural, societal, and other barriers affecting acceptance and uptake of the vaccine will be critical for overcoming vaccine hesitancy and countering misinformation.”

This research was funded by a grant from Instituto de Salud Carlos III and various other grants. Dr. Bruni and coauthors said they have no relevant disclosures.
