Among persons aged 1217 years, reactions after Pfizer-BioNTech booster vaccination were generally mild to moderate and transient; the frequency of local and systemic reactions reported to v-safe after a booster dose were equal to or slightly higher than after the second primary dose. VAERS accepts reports from health care providers, vaccine manufacturers, and members of the public. 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 children aged 511 and persons aged 1215 years, the study period began 5 weeks after the Pfizer-BioNTech vaccine was authorized for each age group (November 2, 2021, and May 12, 2021, respectively). The U.S. Centers for Disease Control and Prevention has more on RSV. In addition, the age SMD calculation comparing negative SARS-CoV-2 test result and positive SARS-CoV-2 test result was generated by directly calculating the SMD for negative SARS-CoV-2 test result and positive SARS-CoV-2 test result. The report by the FDA indicates that the COVID-19 Pfizer vaccine has over 1 200 side effects, that were not disclosed to the public, until last week.
