SARS Vaccination Reactions
Background: Allergic reactions have been reported to occur after vaccination with both the Pfizer-BioNTech COVID-19 Vaccine and Moderna COVID-19 Vaccine. Allergic reactions range from mild to severe and include life- threatening anaphylactic reactions, although no deaths have been reported with either vaccine. This study is designed with two principal aims: - To estimate the proportions of systemic allergic reactions to the Pfizer-BioNTech COVID-19 Vaccine and the Moderna COVID-19 Vaccine in a High-Allergy/Mast Cell Disorder (HA/MCD) population, and - If the risk in the HA/MCD is demonstrable, to determine whether the proportions are higher in the HA/MCD compared to a non-atopic population.
Systemic Allergy Reactions to SARS-CoV-2 Vaccination (COVID-19-004)
This is a multicenter, randomized, initially blinded (masked), phase 2 trial to assess SARS-CoV-2 vaccination reactions in two populations: - One population including individuals with a history of allergic reactions or Mast Cell Disorder (HA/MCD),and - One non-atopic population. Approximately 2040 HA/MCD and 1360 non-atopic participants will be enrolled across participating sites in the United States. Approximately two-thirds of participants enrolled in each of the 2 groups will be female. This is because the vast majority of cases of anaphylaxis to the COVID-19 vaccines have occurred in women. Enrollment of participants who qualify only on the basis of reactions to multiple unrelated drugs will be limited to approximately 300. Enrollment of the MCD group is anticipated to be at least 200 participants, and not more than 300 participants. Participants in each population will be randomized 2:2:1:1 to receive the Pfizer-BioNTech COVID-19 Vaccine, Moderna COVID-19 Vaccine, placebo + Pfizer-BioNTech COVID-19 Vaccine, or placebo + Moderna COVID-19 Vaccine. Participants randomized to one of the placebo groups will receive placebo as a first dose and will receive two doses of their assigned active vaccine at subsequent visits. During the first visit, all participants will be initially-blinded to whether they are receiving placebo or vaccine, and to which vaccine they are receiving. Due to the different dosing schedules for the Pfizer-BioNTech COVID-19 Vaccine and Moderna COVID-19 Vaccine, it will become apparent to both the site staff and the study participant which vaccine has been assigned, once the second injection visit is scheduled. However, the blind over placebo versus vaccine will remain in effect until after the second visit. During a follow-up call, scheduled 3 days after the second injection, participants will be unblinded as to whether they received placebo or active vaccine. Study Duration: Randomized and vaccinated participants will complete study participation in approximately 29 days if vaccinated with the Pfizer-BioNTech COVID-19 Vaccine, 36 days if vaccinated with the Moderna COVID-19 Vaccine, and 50 or 64 days if administered placebo before receiving two doses of either the Pfizer-BioNTech COVID-19 Vaccine or the Moderna COVID-19 Vaccine, respectively. Total study duration: Approximately 17 weeks.
