COVID 19 – Pfizer Vaccine Information

Pfizer Vaccine

Pfizer is a messenger RNA (mRNA) vaccine. This type of vaccine uses a genetic code called RNA to make your body’s cells produce the coronavirus’ specific spike protein.

Your immune system cells then recognise the spike protein as a threat and begin building an immune response against it. The RNA from the vaccine does not change your DNA in any way, and your body quickly breaks it down.

Pfizer does not contain any live virus and it cannot give you COVID-19.
