Severe allergic reactions to the vaccines have been very rare and mostly occurred in people who have had previous severe allergic reactions. People who have had severe allergic reactions, also called anaphylaxis, to any ingredient in the Pfizer, Moderna, or Novavax vaccines should not get that vaccine. People who have had this type of severe allergic reaction to any vaccine or treatment should talk with their health care provider about the risks and benefits of getting vaccinated. People with allergies to foods, animals, environmental triggers (such as pollen), latex, or medications taken by mouth can be vaccinated with any of the COVID-19 vaccines. The same is true if you have family members who have had severe allergic reactions. You will be screened before getting the vaccine to see if you are at an increased risk for an allergic reaction. If you are, your health care provider may decide that you should not get the vaccine. Most reactions occur within a few minutes to one hour after getting vaccinated. You will be asked to stay at the place where you got your vaccine for a short time (15-30 minutes) for monitoring to ensure your safety.
