On Dec. 12, the Centers for Disease Control And Prevention’s (CDC) Advisory Committee on Immunization Practices (ACIP) released their clinical considerations for the use of Pfizer’s COVID vaccine. In their recommendations, they say that “vaccine providers should observe patients after vaccination to monitor for the occurrence of immediate adverse reactions.” Patients with a history of anaphylaxis (severe allergic reactions) for any reason should be monitored for at least 30 minutes after their vaccine shot, the ACIP recommends. Those that have a history of food, pet, insect, venom, environmental, latex, or other allergies and have experienced an allergic reaction (but not anaphylaxis) should be monitored for at least 15 minutes. “About one out of every million people that get a vaccine can have a severe allergic reaction to the vaccine,” Paul Offit, MD, a member of the Food and Drug Administration’s (FDA) vaccine advisory committee, told CNN on Dec. 17. “What we need to find out is what specifically seems to be inducing this allergic reaction.” Until then, Offit echoes the ACIP’s recommendation. “If you have a history of severe allergic reactions, then what you should do is you get the vaccine, but you have to wait for 30 minutes in the area to make sure that you can get the shot of epinephrine that will make those symptoms go away,” he said. The FDA requires that necessary supplies to treat allergic reactions “must be immediately available for administration” following the vaccine shot, in case an anaphylactic reaction occurs. According to the Food Allergy Research and Education organization, “40 percent of children with food allergies and more than half of adults with food allergy have experienced a severe allergic reaction such as anaphylaxis.” And that’s just allergies from food, which an estimated 32 million Americans have. It’s important to note that allergic reactions to the vaccine are still considered rare.

Many vaccine shots can produce swelling in the arm, and the COVID vaccine isn’t any different. The CDC says that a little discomfort and swelling isn’t abnormal, but if you do experience redness or tenderness in that spot that gets worse after 24 hours, you should contact your healthcare provider.
