Is blood an ingredient in any of the vaccines?

Question: 

Is blood an ingredient in any of the vaccines?

Answer: 
Human blood products are not typically found in vaccines. The exceptions to this are two rabies vaccines (Imovax® Rabies and RabAvert®) that contain albumin derived from human blood. There are no blood products in the five COVID-19 vaccines that are currently approved in Canada. This could change as more vaccines with different ingredients are announced, so we recommend looking at the vaccine ingredient list on the Health Canada COVID-19 vaccine website.
 
Regarding other vaccines: animal and human cell cultures may be used in the process of making certain vaccines, but the vaccines do not contain animal or human cells or tissue.
