A pair of new studies yesterday details lower rates of routine vaccinations amid the COVID-19 pandemic, one showing reduced weekly immunization rates and up-to-date status in US children, and the other identifying fewer vaccine doses among both kids and adults in Michigan.
Fewer children up to date on immunizations
An observationalstudypublished inJAMA Pediatricsanalyzed data from US health systems participating in the Vaccine Safety Datalink, an ongoing collaboration between health plans and the Centers for Disease Control and Prevention.
Eight health systems from California, Colorado, Minnesota, Oregon, Washington, and Washington contributed data on children 0 to 18 years from before and during the pandemic. Of the roughly 1.4 million children in 2019 and 2020, 49.0% were female, 11.9% were Asian, 32.1% were Hispanic, 7.2% were Black, and 32.4% were White.
Relative to 2019 and Jan 5 to Mar 14, 2020 (prepandemic), the period of Mar 15 to May 16, 2020 (age-limited preventive care) saw lower weekly recommended childhood vaccination rates—such as for measles, mumps, and rubella—per 1,000 population for all age-groups (eg, 160.1 in 2020 vs 194.6 in 2019 in those younger than 24 months).
