Australia Chief Health Officer After 2,3,4 doses 10's of thousands still getting infected

Australia's Chief Health Officer:
April 2022 stated: "Getting that 3rd dose is protection against severe illness but also preventing getting infected in the first place.
August 2022 he stated: "despite 2,3,4 doses of the vaccine, it's not so good at preventing infection in the first place, so we are getting infected. That's why we've had 10's of thousands of cases in this wave."
