ATAGI recommends an additional booster dose of COVID-19 vaccine to increase vaccine protection before winter for selected population groups who are at greatest risk of severe illness from COVID-19 and who have received their primary vaccination and first booster dose. These groups are:
- Adults aged 65 years and older
- Residents of aged care or disability care facilities
- People aged 16 years and older with severe immunocompromise (as defined in the ATAGI statement on the use of a 3rd primary dose of COVID-19 vaccine in individuals who are severely immunocompromised)
- Aboriginal and Torres Strait Islander people aged 50 years and older.
The additional winter booster dose can be given from 4 months or longer after the person has received their first booster dose, or from 4 months after a confirmed SARS-CoV-2 infection, if infection occurred since the person’s first COVID-19 booster dose.
ATAGI recommends that the rollout of the additional booster dose for these groups starts from April 2022, coinciding with the rollout of the 2022 influenza vaccination program.
Influenza vaccine can be co-administered with the additional booster dose of COVID-19 vaccine. However, if a person is not yet eligible for their additional booster dose, influenza vaccine could be given ahead of the additional booster dose.
| Target group | Recommendation for additional booster dose | Comments/information gaps/next steps |
|---|---|---|
| People aged ≥65 years | Recommended | Recommended from 4 months after the previous booster dose, or from 4 months after previous SARS-CoV-2 infection if this occurred since the previous booster dose. |
| Residents of aged care or disability care facilities | Recommended | Includes people with disability in group residential care facilities. Includes people in residential aged care or disability care who are aged <65 years. Recommended from 4 months after the previous booster dose, or from 4 months after previous SARS-CoV-2 infection if this occurred since the previous booster dose. |
| People who are severely immunocompromised aged ≥16 years | Recommended for people with severe immunocompromise, as defined in the ATAGI statement on use of a 3rd primary dose of COVID-19 vaccine in individuals who are severely immunocompromised | This will be a 5th dose as this group is recommended to receive 3 primary doses.

| People aged <65 years with medical conditions that may increase their risk of COVID-19[1] | Not currently recommended. Remains under active consideration | Complete primary schedule. Promote first booster dose, if not already given. ATAGI will continue to evaluate emerging evidence over the coming weeks. |
| Health care, aged care and disability care workers | Complete primary schedule. Promote first booster dose, if not already given. ATAGI will continue to evaluate emerging evidence over the coming weeks. Maximise up to date vaccination of patients under care. | |
