The Australian Technical Advisory Group on Immunisation (ATAGI) has recommended an additional winter booster dose (fourth dose for most people) for the highest risk groups.
These groups are people aged 65 years and above, residents of aged care or disability care facilities, people with severe immunocompromise and Aboriginal and Torres Strait Islander people aged 50 years or above.
In this updated advice released on 25 March 2022, an additional winter booster is now also recommended for other people at increased risk, to be given 4 months after their first booster dose. This applies to people aged 16-64 who have:
- A medical condition that increases the risk of severe COVID-19 illness (see Table 1 for expanded groups).
- People with disability with significant or complex health needs or multiple comorbidities which increase risk of poor outcome from COVID-19.
