Measles on the Run; 40 Million Children susceptible

About 40 million children are dangerously susceptible to measles threat as they missed the vaccine in 2021, according to World Health Organisation.

The organisation said that measles vaccination coverage steadily declined since the beginning of the COVID-19 pandemic. About 25 million children missed their first dose and an additional 14.7 million children missed their second dose, said a joint publication by the World Health Organization (WHO) and the United States Centers for Disease Control and Prevention (CDC) reports. The report also mentioned that the decline was a significant setback in global progress towards achieving and maintaining measles elimination and leaves millions of children susceptible to infection.


In 2021, an estimated nine million cases were detected and 1,28,000 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 report stated.

Stating that situation was grave, WHO Director-General Dr Tedros Adhanom Ghebreyesus said, “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.”

“Getting immunization programmes back on track is absolutely critical. Behind every statistic in this report is a child at risk of a preventable disease,” he said.


The experts noted that coverage of 95% or greater of 2 doses of measles-containing vaccine is needed to create herd immunity in order to protect communities and achieve and maintain measles elimination. However, 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, the report said. “These are the lowest global coverage rates of the first dose of measles vaccination since 2008, although coverage varies by country,”it  said.


Since 2016, 10 countries that had previously eliminated measles experienced outbreaks and reestablished transmission.

“The record number of children under-immunized and susceptible to measles shows the profound damage immunization systems have sustained during the COVID-19 pandemic,” said CDC Director Dr. Rochelle P. Walensky. “Measles outbreaks illustrate weaknesses in immunization programs, but public health officials can use outbreak response to identify communities at risk, understand causes of under-vaccination, and help deliver locally tailored solutions to ensure vaccinations are available to all.” 

Delays increase the risk of measles outbreaks, so the time for public health officials to accelerate vaccination efforts and strengthen surveillance is now. CDC and WHO urge coordinated and collaborative action from all partners at global, regional, national, and local levels to prioritize efforts to find and immunize all unprotected children, including those who were missed during the last two years.

Measles outbreaks illustrate weaknesses in immunization programs and other essential health services. To mitigate risk of outbreaks, countries and global stakeholders must invest in robust surveillance systems. Under the Immunization Agenda 2030 global immunization strategy, global immunization partners remain committed to supporting investments in strengthening surveillance as a means to detect outbreaks quickly, respond with urgency, and immunize all children who are not yet protected from vaccine-preventable diseases. 

Measles is a childhood infection caused by a virus. Also called rubeola, measles spreads easily and can be serious and even fatal for small children. Also called rubeola, measles spreads easily and can be serious and even fatal for small children.
