7 July 2022 - ATAGI has updated its recommendations for a winter dose of COVID-19 vaccine to help reduce severe disease from the emerging surge of Omicron BA.4 and BA.5 subvariant infections, and to reduce the burden on Australian hospitals and the healthcare system in coming months.

The updated recommendations are:

• Adults aged 50 to 64 years are now recommended to receive a winter booster dose of a COVID-19 vaccine.
• Adults aged 30 to 49 years can receive a winter booster dose of a COVID-19 vaccine, however the benefit for people in this age group is less certain.
• The interval recommended between a recent SARS-CoV-2 infection or the first booster dose and a winter booster dose is now 3 months.
