A US official admits that some recipients of the “Pfizer” vaccine have experienced unexpected allergic symptoms.

An American health official confirmed that the vaccine against the Corona virus, developed by the American “Pfizer” and the German company “Biontech”, had caused an allergic reaction in a number of people vaccinated with this virus in the United States.

The director of the Center for Biology Assessment and Research of the United States Food and Drug Administration (FDA), Peter Marks, told a press conference on Friday that an investigation is underway into the appearance of symptoms allergic in at least five people after receiving the vaccine, indicating that these cases have been recorded in more than one state, including Alaska.

The official suggested that the reason for the appearance of these unexpected symptoms is due to the polyethylene glycol (PEG) contained in the “Pfizer” vaccine, as well as the “Moderna” vaccine which was approved by the United States yesterday.

And media have mentioned reports of two similar cases that occurred last week in Britain, where the Corona vaccination campaign with the “Pfizer” vaccine was launched.
