The majority of systemic events were mild or moderate in severity, after both doses. In addition, reactogenicity data from adolescents aged 12-15 years were obtained and reviewed, and were similar to those from adults aged 18-55 years.

Approximately 129,000 U.S. adolescents aged 12-17 years enrolled in v-safe after Pfizer-BioNTech vaccination; they reported local (63.4%) and systemic (48.9%) reactions with a frequency similar to that reported in preauthorization clinical trials. ACIP conducted a risk-benefit assessment based in part on the data presented in this report and continues to recommend the Pfizer-BioNTech COVID-19 vaccine for all persons aged 12 years (6). CDC and FDA will continue to monitor for adverse events, including myocarditis, after mRNA COVID-19 vaccination and share available data with ACIP to guide risk-benefit assessments for all COVID-19 vaccines.

Local reactions were reported by half (48%) of vaccine recipients and at higher rates than placebo recipients. We also note that longer-term efficacy from the adult RCT and strong vaccine effectiveness observed during post-authorization use in adults suggest that short-term efficacy will translate to longer-term efficacy. This data is presented in Table 8 below. An EB05 2 (more than twice expected) was considered the threshold for defining a vaccine-event pair reported disproportionately. This was observed with a median follow-up of two months, prompting concern for indirectness due to the short duration of follow-up (i.e., observed outcome of vaccine efficacy at two months does not directly inform vaccine efficacy for any duration longer than two months). Impressions regarding cause of death did not indicate a pattern suggestive of a causal relationship with vaccination; however, cause of death for some decedents is pending receipt of additional information. "They need to do research and figure out why this happened, especially to people in the trial. 100,000 people each year develop myocarditis .

We take your privacy seriously. The critical harm of interest was serious adverse events, including vaccine-associated enhanced disease; reactogenicity grade 3 was deemed an important harm. Serious adverse events were more common in vaccine recipients, but certainty in the estimate was very low (RR: 2.50; 95% CI: 0.49, 12.84). Otherwise, occurrence of severe adverse events involving system organ classes and specific preferred terms were balanced between vaccine and placebo groups.

First, VAERS is a passive surveillance system and is subject to underreporting and reporting biases (7); however, under EUA, health care providers are required to report all serious events following vaccination. Health Conditions . The median time to onset was 2-3 days after either dose and all cases resolved within 2 weeks. Patient-important outcomes (including benefits and harms) for assessment were selected by the Work Group during Work Group calls and via online surveys where members were asked to rate and rank the importance of relevant outcomes.

After dose 1, the younger age group reported pain more frequently than the older age group (83.1% vs 71.1%); a similar pattern was observed after dose 2 (77.8% vs 66.1%). Two serious adverse events were considered by U.S. Food and Drug Administration (FDA) as possibly related to vaccine: shoulder injury possibly related to vaccine administration or to the vaccine itself, and lymphadenopathy involving the axilla contralateral to the vaccine injection site. TUCKER CARLSON: IF PUBLIC OFFICIALS KEEP ACTING LIKE THIS, THERE MAY BE A REVOLUTION, "The response with the person that's leading the vaccine trial has been atrocious," she said. In addition to data on symptomatic COVID-19 cases, immunobridging data comparing GMTs in 12-15 year-olds to those in 16-25 year-olds in whom clinical efficacy was previously established was provided in support of efficacy. Vaccine efficacy based on relative risk of 0.03 (95% CI 0.00, 0.49) differs from calculations provided by the sponsor and FDA, which do not include a continuity correction and are based on person-time analyses.

Centers for Disease Control and Prevention. Myocarditis has been observed after vaccination with mRNA vaccines in postauthorization monitoring. Young people at greater risk of serious illness if they catch. Lymphadenopathy occurred in the arm and neck region and was reported within 2 to 4 days after vaccination. The most common serious adverse events in the vaccine group which were numerically higher than in the placebo group were appendicitis (7 in vaccine vs 2 in placebo), acute myocardial infarction (3 vs 0), and cerebrovascular accident (3 vs 1). The majority of systemic events were mild or moderate in severity, but there was a higher occurrence of grade 3 or higher reactions in the vaccine group. Pain/tenderness at the injection site was the most frequent and severe reported solicited local reaction among vaccine recipients. Reports of lymphadenopathy were imbalanced with 6 more cases in the vaccine group (7) than the placebo group (1); lymphadenopathy is plausibly related to the vaccine.

Mild local and systemic reactions are common among adolescents following Pfizer-BioNTech vaccine, and serious adverse events are rare. Under COVID-19 vaccine EUA requirements, health care providers must report certain adverse events after vaccination to VAERS, including death. Signs, symptoms, and diagnostic findings in VAERS reports are assigned Medical Dictionary for Regulatory Activities (MedDRA) preferred terms by VAERS staff members. VAERS reports are classified as serious if any of the following are reported: hospitalization or prolongation of hospitalization, life-threatening illness, permanent disability, congenital anomaly or birth defect, or death. Reports of serious adverse events receive follow-up to obtain additional information, including medical records; for reports of death, death certificates and autopsy reports are obtained, if available. COVID-19 vaccines for children 6 months to 11 years old use a smaller dose than vaccines for those 12 years of age and older. Sect.
