Severe allergic reactions to vaccines are very rare, even for people who have a history of allergies to food, pets, environmental factors, or oral medications. Still, UT Southwestern is following the CDC’s recommendations and observing patients for 15 minutes in a safe environment after vaccination to monitor for any adverse effects.
Patients who have had a severe allergic reaction to a vaccine, an intravenous medication, or an injectable in the past should discuss COVID-19 vaccination with their provider. In the majority of cases, you can still get the vaccine but with a 30-minute observation period instead.
If you’ve had a severe allergic reaction to one of the components in the COVID-19 vaccines, such as polyethylene glycol or polysorbate, it is recommended that you do NOT get one of the currently available COVID-19 vaccines. Also, if you’ve had a severe or immediate allergic reaction to the first dose of a COVID-19 vaccine, you should NOT get the second dose until you discuss the specifics of the reaction with your provider.
