Australian States Agree ‘In Principle’ to Vaccination Rollout Changes National Cabinet has agreed to make a number of changes to Australia’s COVID-19vaccination program, including options to bring forward vaccinations to those over the age of 50. “National Cabinet agreed in principle to a series of changes to the Australian COVID-19 vaccination strategy that will be put forward for approval at the next meeting of National Cabinet (on Thursday),” Prime Minister Scott Morrison said after a meeting with state and territory ministers on April 19. Preparing mass vaccinations sites are among the proposed changes to be discussed on April 22. Morrison said that vaccinating vulnerable groups under phase 1a and 1b also remains a priority, with general practice as the primary model of the rollout.
