The Australian Technical Advisory Group on Immunisation (ATAGI) has released a statement about the need for additional doses of COVID-19 vaccines.
The statement strongly recommends maximising first and second dose vaccine uptake across the community without delay in line with current prioritisation and outbreak response strategies and that two doses of any of the vaccines available in Australia have been shown to protect an individual from COVID-19 and its complications, as well as protecting the community.
ATAGI continues to closely monitor local and international data about the frequency and severity of COVID-19 in fully vaccinated individuals as well as reviewing the international data on the efficacy, effectiveness and safety of additional doses for specific high-risk patient populations, including immunocompromised individuals, and the population more generally. These data will inform future strategies regarding additional vaccine doses.
Additional doses can be defined as:
- Third doses: Additional COVID-19 doses required as part of the primary course to reach a comparable (optimal) level of protection
- Booster dose: Additional COVID-19 doses required at a broader population level, to optimise protection due to waning of immunity (loss of protection) over time, with booster doses also leading to improved immune memory.
