The United Kingdom’s Medical and Health products Regulatory Agency is warning against vaccination for those with a history of significant allergic reactions after two people had an adverse reaction to the coronavirus vaccine.
Two National Health Service workers had an anaphylactoid reaction shortly after receiving the vaccine. Both workers had adrenaline auto-injectors for their allergies. The NHS reports that the workers are recovering.
Drugs such as aspirin, certain anti-inflammatory drugs, and opiates can cause such reactions.
The MHRA is initiating an investigation and will issue further advice when the investigation is completed. Pfizer and BioNTech, the makers of the vaccine, are supporting the investigation.
BioNTech stated that people with a history of severe adverse reactions associated with a vaccine were excluded from the clinical trials.
Pfizer added, “In the pivotal phase 3 clinical trial, this vaccine was generally well tolerated with no serious safety concerns reported by the independent Data Monitoring Committee. The trial has enrolled over 44,000 participants to date, over 42,000 of whom have received a second vaccination.”
