The Pfizer vaccine – commonly asked questions

Comirnaty (Pfizer) is approved for use in people aged 12 years and over. The TGA provisionally approved it for use in Australia on 25 January 2021 (for 16 years and over) and 22 July 2021 (for 12 years and over). If you live in or near Alexandra Hills and would like to organise an appointment to get your vaccine, please call One Life Medical on 3824 8144.

What is the Pfizer vaccine dose schedule?

You need two doses of the Pfizer vaccine, given between 3 and 6 weeks apart. You may not be fully protected against COVID-19 until 7 to 14 days after your second dose. 

What are the ingredients in the 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. 

Does the Pfizer vaccine change your DNA?

The RNA from the vaccine does not change your DNA in any way, and your body quickly breaks it down. 

Does the Pfizer vaccine contain any live virus?

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

What are the common side effects of the Pfizer vaccine?

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

  • injection site pain or swelling
  • tiredness
  • headache
  • muscle or joint pain
  • fever and chills

Most side effects are mild and go away within 1 to 2 days. AusVaxSafety data shows that side effects are more common after the second dose. 

What are the rare side effects of the Pfizer vaccine?

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:

  • within 10 days of vaccination
  • particularly after the second dose
  • more often in men under 30

Contact a doctor or go to the hospital immediately if you develop any of the following symptoms after a Pfizer vaccination: 

  • chest pain
  • pressure or discomfort in the chest
  • irregular, skipped heartbeats or ‘fluttering’
  • fainting
  • shortness of breath
  • pain when breathing
