The Food and Drug Administration (FDA) is investigating allergic reactions to the Pfizer coronavirus vaccine that were reported in several states this week.
Peter Marks, director of the FDA’s Center for Biologics Evaluation and Research, told reporters late Friday evening that reactions had been found in more than one state besides Alaska and that the FDA was investigating five reactions.
“We are working closely with the Centers for Disease Control and Prevention (CDC), and we are actually working with our colleagues in the United Kingdom who reported an allergic reaction, of course. I think we will look at all the data we can from each of these reactions to sort out exactly what happened, and try to understand what components of the vaccine can help produce them, “Gunn said.
He added, “I think we have the right remedy at the moment with the availability of treatment for the right allergic reaction … and we will monitor it closely,” he added.
Gunn said the FDA did not specify the cause of these reactions, but gave a chemical indication of a chemical called polyethylene glycol, which is present in vaccines manufactured by Pfizer and Bionettech, as well as Moderna, “may be to blame.” He added that the reaction some people have experienced may be more normal than once thought.
“We will clearly monitor what is going on. We are working very closely with the CDC on this, and there are many meetings between the CDC and the FDA every week to make sure we keep a very close track of what is going on. ”
Reports of an allergic reaction in Alaska Two similar cases were reported in Britain last week, the first nation to approve the Pfizer vaccine.
The FDA’s current guidelines say most Americans with allergies should be cleared to be vaccinated but those who have had a severe reaction to other vaccines should not be vaccinated. It also said on Friday that people with a history of severe allergic reactions to any of Moderna’s shots should avoid taking the vaccine.
“The FDA takes very seriously the safety of medical products that we authorize and validate, and certainly in a vaccine setting, that’s one of the reasons why Dr. Marks and his team set up a very strong surveillance system in collaboration with the CDC. For safety assessment. One of the things the FDA does very well and uniquely is getting to the bottom of events like an allergic reaction, so that we can fully understand the circumstances and communicate well to people and our regulatory decisions.
