Overall, for children ages 5 to 11, the effectiveness of a primary mRNA vaccination series against infection, compared with being unvaccinated, was 59.9% (95% confidence interval 58.5 to 61.2) at 1 month, 33.7% (32.6 to 34.8) at 4 months, and 14.9% (95% CI 12.3 to 17.5) at 10 months after the first dose. Among the 302,486 children 5 to 11 years of age who were vaccinated, there were 42,484 SARS-CoV-2 infections, 52 of which were known to result in hospital admission and only 1 of which resulted in death. Younger kids slightly more protectedīy the end of the study, 584,707 children 5 to 11 years of age who were unvaccinated had 116,108 SARS-CoV-2 infections, 141 of which resulted in hospital admission and 5 of which resulted in death. Vaccination with both Pfizer-BioNTech and Moderna was considered in the study, and the timeframe included infections caused by all lineages of the Omicron variant, including BA.1, BA.2, BA.4, BA.5, BQ.1-BQ.1.1, and XBB-XBB.1.5. ![]() The study looked at the clinical outcomes seen in 1,368,721 North Carolina residents aged 11 years or younger from Octo(Octofor children aged 5 to 11 years and Jfor children aged 0 to 4 years), to January 6, 2023. These findings and others are published in a new study in The Lancet Infectious Diseases. Children under the age of 12 are protected against severe illness from COVID-19 by mRNA vaccines, but the effectiveness decreases over time, as does immunity gained from previous infections.
