Most (91.6%) reports to VAERS for adolescents after a Pfizer-BioNTech booster dose were nonserious and generally similar to those reported for this age group after primary series vaccination (4). Prevalence and Risk Factors of Adverse Effects and Allergic Reactions after COVID-19 Vaccines in a Mexican Population: An Analytical Cross-Sectional Study. The number of observations was insufficient to estimate 3-dose VE for adolescents aged 1215 years. All authors have completed and submitted the International Committee of Medical Journal Editors form for disclosure of potential conflicts of interest. 2022 Aug 26;15:6821-6836. doi: 10.2147/IJGM.S376316.

VE against COVID-19associated ED and UC encounters was substantially lower during the Omicron predominant period than the B.1.617.2 (Delta) predominant period among adolescents aged 1217 years, with no significant protection 150 days after dose 2 during Omicron predominance. Overall, 2-dose VE against COVID-19associated hospitalization was 73%94%. Polack FP, Thomas SJ, Kitchin N, et al. 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 surveillance activities were reviewed by CDC and conducted consistent with applicable federal law and CDC policy.. regarding Pfizer/BioNTech'sproposal for the clinical and post-authorization safety data package for the Biologics License Application (BLA) for ourinvestigational COVID-19 Vaccine (BNT162b2).

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. On. Among children aged 511 years, estimated VE of 2 vaccine doses received 1467 days earlier against COVID-19associated hospitalization was 74%, with wide confidence intervals that included zero (95% CI = 35% to 95%) (Table 2). The odds of reporting an adverse reaction or health impact after dose 2 and booster dose were compared using a multivariable generalized estimating equations model; p<0.05 was defined as statistically significant. VAERS reports for adolescents who received a Pfizer-BioNTech booster dose during December 9, 2021February 20, 2022, were described by serious and nonserious classification, demographic characteristics (i.e., sex and age), and MedDRA preferred terms. Most encounters among adolescents aged 1215 years and 1617 years occurred during the Delta predominant period (14,491 [79.9%] and 8,800 [74.0%], respectively); among children aged 511 years, most (6,424 [70.0%]) occurred during the Omicron predominant period, reflecting differences in the dates when vaccines became available for the respective age groups. 2020;92:14841490.

Four categories of codes were considered: 1) acute respiratory illness, including COVID-19, respiratory failure, viral or bacterial pneumonia, asthma exacerbation, influenza, and viral illness not otherwise specified; 2) nonrespiratory COVID-19like illness diagnoses including cause-unspecified gastroenteritis, thrombosis, and acute myocarditis; 3) respiratory signs and symptoms consistent with COVID-19like illness, including hemoptysis, cough, dyspnea, painful respiration, or hypoxemia; 4) signs and symptoms of acute febrile illness. VAERS is a U.S. national passive vaccine safety surveillance system managed by CDC and FDA that monitors adverse events after vaccination (2). Nonetheless, it is important to be aware of case studies involving these health issues. 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. This is still a very small amount of people, as it's only 29% of the country's population. Among children aged 511 years, VE of 2 doses received 1467 days earlier against COVID-19associated ED and UC encounters was 46% (Table 2).

VAERS received 914 reports of adverse events after Pfizer-BioNTech booster dose vaccination of adolescents; 837 (91.6%) were nonserious and 77 (8.4%) were serious. The findings in this report also align with studies among adults that report lower VEs during Omicron variant predominance (9,10) and an increase in VE after receipt of a third vaccine dose (9,10). Interim clinical considerations for use of COVID-19 vaccines currently authorized or approved in the United States. 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). Pfizer has also taken a multiple actionsto help alleviate the large increase of adverse eventreports. Pfizer's document is dated April 2021, and the FDA recently released it in response to a Freedom of Information Act (FOIA) request from Public Health and Medical Professionals for Transparency,. Vaccination was defined as having received the listed number of doses of an mRNA-based COVID-19 Pfizer-BioNTech vaccine 14 days (for 2 doses) or 7 days (for 3 doses) before the medical event index date, which was the date of respiratory specimen collection associated with the most recent positive or negative SARS-CoV-2 test result before medical event or the admission date if testing only occurred after the admission. * 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. During December 9, 2021February 20, 2022, approximately 2.8 million U.S. adolescents received a Pfizer-BioNTech booster dose.

Among adolescents, reports to v-safe and VAERS after receipt of a booster dose were generally similar to those previously described after a primary series dose, reinforcing that vaccination among this population is safe (4,5). FDA advisors were also split, 7-4 with one abstention, on the safety for the Pfizer vaccine. We await the expertise and qualified information from Prof Tulio to confirm if this is anything the vaccinated should be concerned about.
