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.

Common side effects

As with any vaccine, you may have some temporary side effects after receiving Pfizer. This shows your immune system is working. Common side effects after Pfizer include:

Rare side effects

In rare cases, myocarditis (inflammation of the heart) and pericarditis (inflammation of the membrane around the heart) can develop after vaccination with Pfizer. Most cases have mild symptoms and recover well.

The TGA reports that these rare effects on the heart typically occur:

pressure or discomfort in the chest
irregular, skipped heartbeats or ‘fluttering’
