Q. HOW DOES THE MODERNA VACCINE DIFFER TO THE OTHER TWO CURRENTLY AVAILABLE IN AUSTRALIA (PFIZER AND ASTRAZENECA)?

A.The Moderna (Spikevax) Covid-19 vaccine is a Messenger RNA (mRNA) vaccine. The Pfizer (BioNTech) vaccine is also an mRNA vaccine, while AstraZeneca (Vaxzevria) is known as a vital vector vaccine.

Both vaccine types deliver genetic code instructions to make a Covid-19 spike protein, which leads to an immune response that is designed to prevent you becoming ill from Covid-19.
