The U.S. Centers for Disease Control and Prevention (CDC) said Saturday they were monitoring reports of allergic reactions to the COVID-19 vaccine and made recommendations on how people with a history of allergies should act.
Anyone who has had a severe reaction to a COVID-19 vaccine should not receive the second dose, the agency said, defining severe as the need for the drug epinephrine or treatment in a hospital.
People who have had a severe allergic reaction to any ingredient in a COVID-19 vaccine should avoid the vaccine formulation that contains the ingredient, the CDC said. Two vaccines have been approved in the United States with emergency use authorizations.
People with a history of severe allergic reactions to vaccines should consult their doctors about injecting COVID-19. The CDC said that people with severe allergies to food, pets, latex, or environmental conditions, as well as people with allergies to oral medications or a family history of severe allergic reactions, could still get vaccinated.
The US Food and Drug Administration is investigating about five allergic reactions that occurred after people were given the COVID-19 vaccine from Pfizer Inc and BioNTech SE in the United States this week.
On Friday, the FDA said the Moderna Inc vaccine, which received emergency use authorization, should not be given to people with a known history of a serious allergic reaction to any component of the injection.
Britain’s medical regulator has said that anyone with a history of anaphylaxis or severe allergic reactions to a drug or food should not receive the Pfizer-BioNTech COVID-19 vaccine.
