Vastavam web: The UK Medicine Regulator says anyone with a history of anaphylaxis to Medicine or food should not receive the Pfizer-Bioentech COVID-19 vaccine, which provides complete guidance on previous allergy warnings about the shot. Starting with the elderly and frontline workers, UK began vaccinating its population on Tuesday, one of the biggest transportation challenges in the history of peace as part of a global drive. Medicines and Healthcare Products Regulatory Agency (MHRA) says there have been two reports of anaphylaxis and one report of an allergic reaction since the rollout began.

“Anyone with a history of anaphylaxis to the vaccine, medicine or diet should not take the Pfizer Bioentech vaccine,” MHRA Chief Executive June Rain said in a statement. Anaphylaxis is an overreaction of the body’s immune system that the National Health Service describes as serious and sometimes fatal. The fuller guidance stating that MHRA initially advised not to take the shot to anyone with a history of a “significant allergic reaction”.

Last week, Britain’s MHRA was the first in the world to approve a vaccine developed by Germany’s biotech and Pfizer, the US. The Food and Drug Administration (FDA) and the European Medicines Agency (EMA) continue to evaluate the data. The U.S. has warned that Americans with severe allergic reactions may not be candidates for Pfizer’s COVID-19 vaccine. A senior official said Wednesday. MHRA Chief Raine told lawmakers that such allergic reactions were not a symptom of Pfizer’s clinical trials.
