Contraindications and Precautions
Contraindications to COVID-19 vaccination include:
- Severe allergic reaction (e.g., anaphylaxis) after a previous dose or to a component of the COVID-19
- Known diagnosed allergy to a component of the COVID-19 vaccine
People with a contraindication to one type of COVID-19 vaccine (i.e., mRNA COVID-19 vaccines or Janssen COVID-19 Vaccine) should not receive additional doses of that type of COVID-19 vaccine. However, people with a contraindication to mRNA COVID-19 vaccines may be able to receive Janssen COVID-19 Vaccine, and vice versa, provided certain measures are taken.
