As children under 5 wait for FDA approval of a COVID-19 vaccine, some kids still need to catch up on routine vaccines for other diseases, including measles, mumps, and meningitis. According to UNICEF and the WHO, 23 million children globally missed out on basic childhood vaccines that are typically received through routine health services in 2020. Some children in the U.S. caught up last year, but the vaccination rate was still 7 percent lower than years before the pandemic. That’s according to the Centers for Disease Control and Prevention.
