Updated Dec. 31, 2020 This webpage provides recommendations on what to do if you experience an allergic reaction after getting a COVID-19 vaccination. It also provides recommendations for people who have had allergic reactions to other vaccines and for those with other types of allergies. This page will be updated when we get new information. If you get a COVID-19 vaccine and you think you might be having a severe allergic reaction after leaving the vaccination site, seek immediate medical care by calling 911.
