The Australian Technical Advisory Group on Immunisation (ATAGI) has recommended a third dose of a COVID-19 vaccine for people who are ‘severely’ immunocompromised. This is because people who have certain conditions – or who are on immunosuppressive therapies such as chemotherapy – might not be fully protected by the regular two doses of a vaccine.
People eligible for a third dose of vaccine includes people with active cancers, organ transplants, recent stem cell transplants, people on immunosuppressive medications or taking high doses of steroids, people born with immunodeficiencies, and people on long-term dialysis.
The third dose is recommended two to six months after their second dose. A minimum of four weeks may be considered in exceptional circumstances. The Pfizer and Moderna vaccines are preferred to AstraZeneca, but AstraZeneca can be used for people who have received this vaccine for their first two doses.
If you believe you are eligible to have a third dose you should contact your treating medical practitioner who can advise you further and, if they are participating in the COVID 19 vaccination program, will provide you with the third dose.
