Anaphylaxis, an acute and potentially life-threatening allergic reaction, has been reported rarely following COVID-19 vaccination. These interim considerations provide recommendations on assessment and potential management of anaphylaxis following COVID-19 vaccination. Detailed information on CDC recommendations for vaccination, including contraindications and precautions to vaccination, can be found in the Clinical Considerations for Use of COVID-19 Vaccines Currently Authorized in the United States. Patients should be screened prior to receipt of each vaccine dose, and those with a contraindication should not be vaccinated. A COVID-19 prevaccination questionnaire pdf icon[6 pages] is available to assist with screening.
Healthcare personnel who are trained and qualified to recognize the signs and symptoms of anaphylaxis, as well as administer intramuscular epinephrine, should be available at the vaccination location at all times. Vaccination locations that anticipate vaccinating large numbers of people (e.g., mass vaccination clinics) should plan adequate staffing and supplies (including epinephrine) for the assessment and potential management of anaphylaxis.
