WHO and CDC warn world at risk of measles outbreaks as COVID-19 disrupts infant shots

Reading Time: 2 minutes

The risk of measles outbreaks is high after more than 22 million infants missed their first vaccine doses during the COVID-19 pandemic in 2020, the World Health Organization (WHO) and the U.S. Centers for Disease Control and Prevention (CDC) warned.

Reported measles cases fell by more than 80% last year compared with 2019, but a higher number of children missing their vaccine doses leaves them vulnerable, a joint report by the WHO and the U.S. CDC showed.

About 3 million more children missed the shots in 2020 than the previous year, the largest increase in two decades, threatening global efforts to eventually eradicate the highly infectious viral disease.

“Large numbers of unvaccinated children, outbreaks of measles, and disease detection and diagnostics diverted to support COVID-19 responses are factors that increase the likelihood of measles-related deaths and serious complications in children,” the U.S. CDC’s immunization head, Kevin Cain, said.

Measles is one of the most contagious diseases known, more so than COVID-19, Ebola, tuberculosis or flu. It can be especially dangerous for babies and young children, with pneumonia among the possible complications.

In 2019, reported cases of measles were at their highest in almost a quarter of a century.

The latest report said 24 measles vaccination campaigns originally planned for 2020 in 23 countries were postponed, leaving more than 93 million people at risk.

“It’s critical that countries vaccinate as quickly as possible against COVID-19, but this requires new resources so that it does not come at the cost of essential immunization programs,” said Dr Kate O’Brien, director of the WHO’s department of immunization, vaccines and biologicals.

“Routine immunization must be protected and strengthened; otherwise, we risk trading one deadly disease for another,” she said.
