Let’s face it: it’s been a long road, this pandemic. Are you powering on, or just crawling along as best you can?
Either way, for most Australians there’s hope on the horizon. This hope comes in the form of a small vial and 2 jabs in the arm. As our vaccination rates increase, so does our hope that some of the burdens of this pandemic will lift.
What are the vaccines currently available to Australians? And what’s the difference between them?
Will these differences matter for you?
Find out the key facts here.
Vaccines are a safe and effective way to help your immune system prepare its defence against deadly germs. We use vaccines to combat the health issues and spread of lots of major illnesses including:
Vaccines are like the training run for the main event. When you have a vaccine, your immune system will create antibodies, just as it does when it’s exposed to a disease.
However, vaccines contain only modified or weakened forms of germs. They do not cause disease.
At present, we have two vaccines in Australia to combat COVID-19, and some more on their way. They are safe and effective. But not they’re not identical.
Firstly, they have been developed using different technologies: mRNA technology, viral vector technology and protein-based technology.
These types of vaccines use messenger-RNA (mRNA, a genetic code). The mRNA provokes cells in your body to produce a COVID-19-specific protein. This is the protein that your immune system will target and attack.
Messenger-RNA vaccines can’t alter or impact your DNA in any way. The Pfizer vaccine and Moderna vaccine are mRNA vaccines.
These types of vaccines use a harmless, weakened animal virus. This virus contains the genetic code for a protein unique to COVID-19. Your body will produce antibodies to this protein.
The AstraZeneca vaccine is a viral vector vaccine.
These types of vaccines are made from a non-infectious protein that mimics part of the virus. In the case of the coronavirus, this is the spike protein (which is on the surface of the virus).
Your body will produce antibodies to this protein.
The Novavax vaccine is a protein-based vaccine.
You can only get the COVID-19 from a live strain of the coronavirus. COVID-19 vaccines do not contain a live strain of the coronavirus. So you cannot get COVID-19 from a shot.
In Australia, the:

The research shows that these vaccines protect against COVID-19 symptoms and severe disease after 2 doses.
We don’t yet know if the COVID-19 vaccines reduce or stop the spread (transmission) of the virus. There is some evidence that it may.
All vaccines have mild side effects, like a sore arm or mild fever. More serious side effects happen but are extremely rare.
You are most likely aware of the news concerning the AstraZeneca vaccine.
It’s linked to a very rare blood-clotting condition called thrombosis with thrombocytopenia syndrome (TTS). The very low risk of TTS appears to be higher in younger adults, which is why it’s preferred for people aged over 60.
However, if you are aged 18 to 59 you can have the AstraZeneca vaccine if you want to. You need to weigh up the benefits and the risks, and provide informed consent.
