You should not get this vaccine if you have a serious allergy (anaphylaxis) to:
- Polysorbate 80 which is in the AstraZeneca/Verity Pharmaceuticals vaccines. It is also found in medical preparations (e.g., vitamin oils, tablets and anticancer agents) and cosmetics
- A previous dose of a COVID-19 vaccine or to any part of the vaccine
Tell your health-care provider if you have had anaphylaxis but no cause was found after seeing an allergy specialist, or if you had anaphylaxis before and did not get seen by an allergy specialist.
The National Advisory Committee on Immunization (NACI) has recommended a temporary suspension of the use of the AstraZeneca/SII Covishield vaccines in Canadians under 55. This is a precautionary measure, as the vaccine may be associated with rare cases of blood clots, totalling less than 30 cases worldwide out of 20 million people who received the vaccine.
