Nearly 40m Children Susceptible to Growing Measles Threat – WHO, CDC
Measles vaccination coverage has steadily declined since the beginning of the COVID-19 pandemic. In 2021, a record high of nearly 40 million children missed a measles vaccine dose: 25 million children missed their first dose, and an additional 14.7 million children missed their second dose, a joint publication by the World Health Organisation (WHO) and the United States Centres for Disease Control and Prevention (CDC) reports.
The decline is seen as a significant setback in global progress towards achieving and maintaining measles elimination and leaves millions of children susceptible to infection.
In 2021, there were an estimated nine million cases and 128,000 deaths from measles worldwide. Twenty-two countries experienced large and disruptive outbreaks. Declines in vaccine coverage, weakened measles surveillance, and continued interruptions and delays in immunization activities due to COVID-19, as well as persistent large outbreaks in 2022, mean that measles is an imminent threat in every region of the world.
“The paradox of the pandemic is that while vaccines against COVID-19 were developed in record time and deployed in the largest vaccination campaign in history, routine immunization programmes were badly disrupted, and millions of kids missed out on life-saving vaccinations against deadly diseases like measles,” said WHO Director-General, Dr Tedros Adhanom Ghebreyesus. “Getting immunisation programmes back on track is absolutely critical. Behind every statistic in this report is a child at risk of a preventable disease.”
The situation, according to WHO and CDC, is grave, adding that measles is one of the most contagious human viruses but is almost entirely preventable through vaccination.
Coverage of 95% or greater of two doses of measles-containing vaccine is needed to create herd immunity in order to protect communities and achieve and maintain measles elimination. The world is well under that, with only 81% of children receiving their first measles-containing vaccine dose, and only 71% of children receiving their second measles-containing vaccine dose. These are the lowest global coverage rates of the first dose of measles vaccination since 2008, although coverage varies by country.
