Today, Australian Technical Advisory Group on Immunisation (ATAGI) has recommended a booster dose of COVID-19 vaccine.

- It is for people 18 years and older who completed their primary COVID-19 vaccine course ≥6 months ago.

- It includes a single dose of Pfizer vaccine irrespective of the primary COVID-19 vaccine used. Although not preferred, Vaxzevria (AstraZeneca) can also be used as a booster dose if there was a significant adverse reaction after a previous mRNA vaccine dose (e.g. anaphylaxis, myocarditis).

- It is acceptable to co-administer a COVID-19 booster vaccine dose with an influenza vaccine

- In severely immunocompromised individuals who have recently been recommended to receive a third dose of a primary COVID-19 vaccine, booster doses (i.e. 4th doses) are not yet recommended
