Allergic reactions to Pfizer’s coronavirus vaccine more frequent than expected: US official

A U.S. official said the frequency of allergic reactions to Pfizer’s coronavirus vaccine is higher than previously predicted, CNN reported.

In an interview with CNN, Dr Moncef Slaoui, Chief Scientific Advisor for Operation Warp Speed, said: “That frequency, as it was yesterday (December 22), is higher than what would be expected with other vaccines. “.

This occurs when the Medicines and Health Products Regulatory Agency (MHRA) issued precautionary advice to the National Health Service (NHS) after two health care professionals reported allergic reactions.

“We know from very extensive clinical studies that this was not a feature. But if we need to strengthen our advice, now that we have had this experience in the vulnerable population – groups have been selected as a priority – we immediately get that advice on the ground, “said Dr. Raine, chief executive of the MHRA, while testifying to a parliamentary commission.

Regulators in the UK have issued advice and asked people with a history of “significant” allergic indications not to take the Pfizer-BioNTech coronavirus vaccine.

Meanwhile, the United States signed an agreement with Pfizer Inc. on Wednesday for an additional 100 million doses of its Covid-19 vaccine.
