Only 4.5% of a cohort of pediatric COVID-19 patients admitted to US hospitals during the period of Omicron predominance had completed their primary COVID-19 vaccine series, and 7.0% had started but didn’t finish the series, The Pediatric Infectious Disease Journal reports.
The study team, led by Centers for Disease Control and Prevention (CDC) researchers, enrolled 597 vaccine-eligible COVID-19 inpatients aged 8 months to 4 years at 28 hospitals participating in the Overcoming COVID-19 network from September 2022 to May 2023. A total of 62.1% of patients were aged 8 months to 1 year, and 37.9% were aged 2 to 4 years.
