Booster vaccines

Who should get a booster shot

Boosters are recommended for:

  • People who are 18 years and older, and
  • Have had the second dose of COVID-19 vaccination at least four months ago

People over the age of 18 who are severely immunocompromised and have receive a third dose as part of their primary course should receive a fourth dose as a booster.

Boosters are not currently recommended for
  • People aged 17 years and younger

Why you should get a booster

Boosters are not mandatory but you need a third dose to keep up your immunity against COVID-19.

A booster dose will continue to protect you, your loved ones and the community against COVID-19.

Vaccine types for booster doses

Pfizer and Moderna can be given for booster vaccines regardless of which vaccine was given for the first two doses.

How to get a booster

Pfizer boosters are available from state-run clinics and participating GPs and pharmacies.

Moderna boosters are available from participating pharmacies.

To get your booster at a state-run clinic:

  • You should book an appointment by visiting www.coronavirus.tas.gov.au/booking or calling the Public Health Hotline on 1800 671 738.
  • You should bring evidence of your vaccination record if you received your first COVID-19 vaccinations at a different provider than a state-run clinic.
  • Evidence includes a paper or digital COVID-19 vaccination certificate. Read more about how to get this evidence.

To get your booster at a GP or pharmacy:

Third primary and fourth doses for people with severe immunocompromise

Who should get a third primary dose

A third primary dose received as part of the primary course is different from a booster vaccine.

A third vaccination is recommended for people who are severely immunocompromised as part of their primary course of vaccination.

The third dose should be given between two and six months after the second dose.

Those eligible for a third dose includes: people with active cancers, organ transplant recipients, recent stem cell transplant recipients, people on immunosuppressive medications or taking high dose steroids, those born with immunodeficiencies and people on long-term dialysis.

Vaccine types for third primary doses

The Pfizer and Moderna vaccines are preferred to AstraZeneca for this third dose, but AstraZeneca can be used for people who have received this vaccine for their first two doses.

How to get a third primary dose

If you think you may be eligible for a third dose of vaccine, talk to your doctor or medical care provider for further information.

If your medical practitioner is participating in the COVID-19 vaccination program, they will provide you with the third dose.

If your medical practitioner is not participating in the COVID-19 vaccination program you should attend a state-run clinic or pharmacy to receive your third dose.

To confirm your eligibility at a state-run clinic, you should bring evidence of your COVID-19 vaccination record AND evidence that you are severely immunocompromised. Evidence could include:

  • A letter from your GP or specialist
  • Documents showing your medical history
  • A copy of your prescription
  • Discharge summary from hospital
  • Or any other document showing your identity and medical history.

People receiving a third primary dose will also need to complete the Commonwealth Eligibility Declaration Form for a third primary dose. This can be completed beforehand or on the day at the clinic.

People attending a state-run clinic for a third dose should attend as a walk-in only (without an appointment). View the full list of state-run clinics here.

To confirm your eligibility at a pharmacy, you must bring evidence that you are severely immunocompromised.

Fourth dose for people with severe immunocompromise

People over the age of 18 who are severely immunocompromised and have received a third dose as part of their primary course should get a fourth dose as a booster, four months after their previous dose.
