Allergic reactions have occurred in five cases in the U.S. this week following administration of Biontech and Pfizer’s coronavirus vaccine. This was announced by the US Food and Drug Administration (FDA) yesterday (local time).
FDA expert Peter Marks said the culprit may be the chemical polyethylene glycol. It is a component of both the Biontech/Pfizer and Moderna vaccines, he said. Immunizations with the Biontech/Pfizer vaccine have been ongoing since Monday, and the Moderna vaccine is expected to be used starting early next week. The U.S. Food and Drug Administration yesterday granted emergency approval for the Moderna vaccine. This is the first approval of the vaccine in the world.
Polyethylene glycol – also known as macrogol – is widely used in pharmaceuticals and also in cosmetics as an active ingredient carrier.
