It has been a busy month learning about #allergy after #COVID19Vaccines but we so excited to receive this broad information from @CDCgov. Highlights below!/1

*Potential #anaphylaxis 175 of 1,893,360 1st doses of @pfizer vaccines (0.009%; 90 per million)
*Confirmed #anaphylaxis, 21 of 1,893,360 1st doses of @pfizer vaccines (0.0011%; 11 per million)
-->Better than we thought (1 per 100,000)but greater than usual 1 per million)/2

*17 of 21 Anaphylaxis cases (81%) had allergy history; 7 of 21 (33%) had prior anaphylaxis
*Anaphylaxis occurred a median of 13 min (2–150 min) after vaccination; 71% occurred within 15 min (i.e., CDC recommended waiting/observation time)
*Follow-up for 20 patients & 100% OK /3

2/#allergy and #anaphylaxis can happen to any #drug or #vaccine, but reactions to #COVID19vaccine are exceedingly rare (~6 in >300K vaccinations so far--> 0.002%). #vaccines have always been a rare cause of allergic reactions in healthcare.
3/Recently we looked at ~3K allergic reactions in healthcare settings @MassGenBrigham: contrasts caused allergy the most & just 6 vaccine reactions in 10-years. @NeelamPhadkeMD @MGH_ClinEpi @lizhou08 @JieHealthAI @PaigeWickner

1/ OK so 1 week after UK #COVID19Vaccine allergy was described, I need to reorient you to my world, the world where #drugallergy is the best field of #MedTwitter #AIMedEd #allergyimmunologyrocks. Let's get down to this confusion about the #covid19vaccine and #allergy
2/ There is no reason to think that anyone -- other than patients with a known allergy to an ingredient in this vaccine or an ingredient cross-reactive to an ingredient in this vaccine -- might have an #allergy the @pfizer #CovidVaccine.
3/ There is even very little that we think could cause an #allergy in this @pfizer vaccine. But 2 patients had #anaphylaxis after vaccination and we need to think about why. Something epidemiologically different in the UK population compared to clinical trial populations?
