Health care providers, parents, and adolescents should be advised that local and systemic reactions are expected among adolescents after a homologous Pfizer-BioNTech booster vaccination and that serious adverse events are rare. Nevertheless, on 8 March 2022, social media birthed a new hashtag - #pfizerdocuments. After their release and widespread use, however, individual case reports and small case series of serious adverse events began to appear including thrombotic thrombocytopenia, that sometimes involved portal or hepatic vein thrombosis and some degree of liver dysfunction, as well as acute liver injury, that often resembled autoimmune hepatitis.

Views equals page views plus PDF downloads. Each VAERS report might be assigned more than one MedDRA PT, which can include normal diagnostic findings; thus, the events listed in the table might sum to more than the total number of reports. Medical events with an encounter or discharge code consistent with COVID-19like illness were included, using International Classification of Disease, Ninth Revision and International Classification of Diseases, Tenth Revision (ICD-10). medical events that have been observed after vacci nation, but which are not necessarily related to or caused by the vaccine. The vaccines have been said to give you the best protection against COVID-19. During Omicron predominance, VE of a second dose received 14149 days earlier was 45% and 34% for adolescents aged 1215 and 1617 years, respectively, suggesting that the lower VE observed among children aged 511 years was likely driven by the predominant variant rather than differences in VE across age groups.

The research further found that the patient's clinical picture was attributed to hepatotoxicity secondary to the Pfizer/BioNTech BNT162b2 mRNA vaccine, the only pharmacological agent that she was exposed to before her current presentation. National Library of Medicine Hospitalization in the week after booster dose vaccination was reported for one adolescent with new onset migraine; whether hospitalization was the result of COVID-19 vaccination could not be determined. Silver Spring, MD: US Department of Health and Human Services, Food and Drug Administration; 2021. A peer reviewed case report detailed a case of hepatotoxicity after receiving a COVID-19 vaccine. Among children aged 511 years during the full study period, VE of 2 doses (1467 days earlier) against COVID-19associated ED or UC encounters was 46%, which was significantly lower than overall estimates for adolescents aged 1217 years. Chronic respiratory condition was defined as the presence of discharge code for asthma, sleep apnea, or other lung disease using ICD-9 and ICD-10 diagnosis codes.

Fatigue has been reported by roughly 63 . and Terms of Use. * Medical events with an encounter or discharge code consistent with COVID-19like illness were included, using ICD-9 and ICD-10. Second, statistical power for estimating VE against COVID-19associated hospitalizations was limited, resulting in wide CIs for some groups, particularly children aged 511 years. "Pfizer began its rolling submission on May 7, 2021, and the vaccine was licensed on August 23, 2021, a total of 108 days from initial submission to licensure," it wrote in a December filing. Partners contributing data on medical events were in California (vaccine availability: April 30, 2021), Colorado (May 22, 2021), Indiana (April 27, 2021), Minnesota and Wisconsin (April 21, 2021), New York (April 27, 2021), Oregon and Washington (April 28, 2021), Texas (March 29, 2021), Utah (April 9, 2021). Vaccination was defined as having received the listed number of doses of COVID-19 Pfizer-BioNTech BNT162b2 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.
