What are the ingredients of COVID-19 vaccines?

Vaccine ingredients depend on the type of vaccine. As vaccines are approved for use, the contents and presentation of each vaccine is published by Medsafe as a data sheet and consumer medicine information.

These form part of the information that companies submit during the approval process. Find the ingredients for the Comirnaty (Pfizer/BioNtech) vaccine here.

Some other types of vaccines use human cell lines in the vaccine manufacturing process. This is known to be a safe and efficient way to produce vaccines. Both the Janssen and Oxford/AstraZeneca COVID-19 vaccine candidates use cell lines. NO cells from the manufacturing process remain in the vaccine because purification removes all the cell culture material and each batch undergoes thorough quality control checks. The Catholic Church has issued a formal statement saying it is morally acceptable to take vaccines that use cell lines. Find further information on fetal cells and COVID19 vaccines here.
