Adults aged 18–64 years who do not have severe immunocompromise are recommended to receive a single primary dose of COVID-19 vaccine, and can consider a further dose every 12 months based on individual preference and a risk-benefit assessment. The risk of severe illness from COVID-19 is low in previously vaccinated healthy adults.3,4
Adults aged 65–74 years who do not have severe immunocompromise are recommended to receive a single primary dose of COVID-19 vaccine and further doses of COVID-19 vaccine every 12 months, and can consider doses every 6 months based on a risk-benefit assessment. A dose every 6 months is most likely to benefit people with medical risk conditions and/or those living in residential care facilities.5,6
All adults aged ≥75 years, including aged care residents, are recommended to receive a single primary dose of COVID-19 vaccine, and further doses of COVID-19 vaccine every 6 months. The risk of severe illness increases significantly with advancing age.7-9
