Among adolescents aged 1215 and 1617 years, VE of 2 doses 14149 days earlier against COVID-19associated ED and UC encounters was 83% and 76%, respectively; VE was significantly lower for 2 doses received 150 days earlier (38% and 46%, respectively). However, in adolescents aged 1617 years, VE during the Omicron predominant period increased to 81% 7 days after a third booster dose. Sixty-four preliminary reports of myocarditis were received, among which 47 were considered serious; 32 (68.1%) of these reports were confirmed by provider interview or medical record review to meet the CDC working definition of myocarditis. During that period, the FDA asserts it conducted an intense, robust, and thorough analysis of those documents to assure the public that the Pfizer vaccine was safe and effective.

VAERS reports are classified as serious if there are any reports of hospitalization, prolongation of hospitalization, life-threatening illness, permanent disability, congenital anomaly or birth defect, or death. For example, the age SMD calculation comparing unvaccinated versus different vaccinated categories was generated by averaging the pairwise SMD calculations for unvaccinated and 2 doses (14149 days earlier), unvaccinated and 2 doses (150 days earlier), and unvaccinated and 3 doses (7 days). Reactions were mostly mild to moderate in severity and most frequently reported the day immediately after vaccination. Pre-Delta refers to the period before Delta predominance. * VE was calculated as [1 odds ratio] x 100%, estimated using a test-negative design, adjusted for age, geographic region, calendar time (days since January 1, 2021), and local virus circulation (percentage of SARS-CoV-2positive results from testing within the counties surrounding the facility on the date of the encounter) and weighted for inverse propensity to be vaccinated or unvaccinated.
