According to Chief Scientific Adviser for Operation Warp Speed Moncef Slaoui, the frequency of allergic reactions to the Pfizer vaccine is higher than the expectations.
Dr. Slaoui added that on Tuesday, six allergic reactions to the vaccine were reported and that vaccinated people are a minority currently compared to the numbers waiting to receive the jab.
“That frequency, as it stood yesterday, is superior to what one would expect with other vaccines,” he admitted.
The top health official said that Pfizer and the National Institutes of Health are discussing clinical trials of vaccines in very allergic populations and those on medication.
The National Institute of Allergy and Infectious Diseases had previously announced that scientists are looking at why the vaccine had triggered severe allergic reactions to the Pfizer shot.
The study will involve “several hundred people” with a history of allergic reactions, Alkis Togias, the NIAID’s Allergy Branch Chief, said.
