The US centres for disease control and prevention (CDC) says it is monitoring reports of allergic reactions to the Covid-19 vaccine. The FDA is investigating five reported allergic reactions that occurred in people who received the Pfizer and BioNTech vaccine in the US this week.

Anyone who had a severe reaction to a Covid-19 vaccine should not get the second dose, the CDC said, defining severe as needing the medication 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 containing the ingredient, agency said. Two vaccines have been approved in the United States under emergency use authorisations.
