NSW Health state-run clinics will offer a booster dose, using the Pfizer COVID-19 vaccine, to individuals aged 18 and over from Monday 1 November.

This booster shot will help people maintain a high level of protection against the COVID-19 virus, including the Delta variant.

People aged 18 years and older may receive a booster at least six months after receiving their second dose of any of the COVID-19 vaccines registered for use in Australia.

The Pfizer COVID-19 vaccine will be offered as the booster dose, regardless of the COVID-19 vaccine received for the first or second dose.

Booster doses will be available throughout the NSW Health vaccination clinic network, including the mass vaccination hubs at Sydney Olympic Park, Macquarie Fields in south-west Sydney, Wollongong and Newcastle.

Eligible people can also receive a booster dose of the Pfizer COVID-19 vaccine from their GP and from participating community pharmacies. A booster vaccination can be booked through the COVID-19 Vaccine Clinic Finder.

For the purposes of complying with public health orders, people who have received two doses of an approved COVID-19 vaccine and completed their 'primary course' are still considered fully vaccinated, but the booster dose is important for strengthening protection against the virus.

NSW Health state-run clinics are already providing a third dose of a COVID-19 vaccine to people aged 12 and older who are severely immunocompromised.

This third dose is part of their primary course as it helps to build an immune response similar to people who are not immunosuppressed.
