Not only does Australia not get updated vaccines in good time, the government has now limited free access. Based on the notion that we all have strong immunity due to infections and previous vax. So it’s basically relying on infections to protect people 😣 - huh?
This virus has evolved. Australia doesn't have a new vaccine
Australia is lagging behind the latest formulations being developed overseas.
