UK Investigating If Severe Allergic Reactions Linked to Pfizer Vaccine
On Wednesday, British regulators warned people that have a history of serious allergic reactions to not take the new Pfizer-BioNTech Covid-19 vaccine as they are in the process of investigating two severe reactions that occurred on the first day of the country's vaccination program.
U.K.’s Medical and Healthcare Products Regulatory Agency is investigating whether the reactions are related to the vaccine. Both of the people who had adverse reactions are staff members of the National Health Service and are recovering.
Said Professor Stephen Powis, medical director for the NHS, "As is common with new vaccines the MHRA have advised on a precautionary basis that people with a significant history of allergic reactions do not receive this vaccination after two people with a history of significant allergic reactions responded adversely yesterday. Both are recovering well.”
Pfizer and BioNTech said they are working with investigators to "better understand each case and its causes." The companies pointed out that late-stage trials of the vaccine presented "no serious safety concerns" and that over 42,000 people have already received the vaccine during those trials.
