Reactions reported after both dose 2 and booster dose vaccination were mostly mild to moderate in severity. Limited real-world data on 2-dose mRNA vaccine effectiveness (VE) in persons aged 1217 years (referred to as adolescents in this report) have also indicated high levels of protection against SARS-CoV-2 (the virus that causes COVID-19) infection and COVID-19associated hospitalization (46); however, data on VE against the SARS-CoV-2 B.1.1.529 (Omicron) variant and duration of protection are limited. These findings are consistent with previously published data showing high effectiveness of the Pfizer-BioNTech vaccine among adolescents before Omicron became the predominant variant (46), and with data from adults demonstrating relatively higher protection against more severe outcomes (7). On January 5, 2022, CDC expanded its recommendation for a booster 5 months after receipt of the second dose of the Pfizer-BioNTech vaccine to include adolescents aged 1215 years (https://www.cdc.gov/media/releases/2022/s0105-Booster-Shot.html).

This includes significant technology enhancements, and process Fifth, genetic characterization of patients viruses was not available, and Delta and Omicron predominance periods were based on surveillance data. *** This analysis excluded reports to v-safe or VAERS of persons aged 1215 and 1617 years who were vaccinated before authorization for a booster dose for their age group (January 3, 2022, and December 9, 2021, respectively). During the full study period, including pre-Delta, Delta, and Omicron predominant periods, VE against laboratory-confirmed COVID-19associated hospitalization among children aged 511 years was 74% 1467 days after dose 2, with wide CIs that included zero. The patient was observed and tested for seven days before being transferred to a liver transplant center for further investigation and management. Meanwhile, about 300 U.S. children under the age of 5 also die from RSV each year. The data in these analyses come from 306 ED and UC clinics and 164 hospitals. These findings are also consistent with data showing a decline in mRNA VE over time since receipt of the second dose among adolescents and adults (810).
