f the 20 cases investigated:
- 81% had a history of allergic reactions. They range from 27 to 60 years old.
- 90% of the cases were women, but that could be because more women have been vaccinated.
- The CDC says 86% of patients said their symptoms started within 30 minutes.
- Almost all were treated with epinephrine.
With the new information in mind, the CDC issued new guidance for vaccination locations. It includes monitoring people who have a history of allergic reactions for 15-30 minutes after their shot.
People with a history of severe allergic reactions who carry EpiPen’s can still get the COVID-19 vaccine. The CDC recommends consulting with a physician first.
