December 19th, local time, according to the Capitol Hill newspaper, the U.S. Food and Drug Administration (FDA) is investigating the allergic reaction after vaccination against Pfizer.
“Aside from Alaska, many states in the United States have reported adverse reactions after vaccination,” said Pete Marks, director of the Bureau of Bioproduct Assessment and Research at the Food and Drug Administration.
FDA is now ready for treatment for serious adverse reactions and will continue to monitor adverse reactions closely in cooperation with the Centers for Disease Control and Prevention.
Max said that the Food and Drug Administration is not sure what causes the adverse reaction at present, but he pointed out that the presence of a chemical called polyethylene glycol (PEG) in the vaccines produced by Pfizer and Moderna may be the culprit. He added that some people may experience more common adverse reactions than previously predicted.
Most Americans with allergies should be vaccinated as usual, but people with serious reactions to other vaccines should not be vaccinated, and people with a history of severe allergic reactions to any component in the Moderna vaccine should avoid the vaccine, according to the current COVID-19 vaccine guidelines issued by the Food and Drug Administration.
