Vaccination rates among kindergarten children against potentially deadly diseases such as polio, measles and diphtheria fell in the 2021-2022 school year, extending the previous year’s slide from pre-pandemic levels, a U.S. government study showed on Thursday.
The fall in rates for the four most commonly required childhood vaccines reflects the disruption caused by COVID-19 on healthcare and the need to restore vaccination coverage to pre-pandemic levels, the U.S. Centers for Disease Control and Prevention (CDC) said of the data it collected.
