A fourth COVID-19 vaccine dose is on the horizon, but Victoria's booster rate remains stubbornly low

Experts have raised concerns about the 'disappointing' rate at which Victorians are getting their booster COVID-19 vaccine doses, as the possibility of a fourth dose is considered. More than 93.7 per cent of eligible Victorians have had two doses of the vaccine, but the latest figures from the health department show 64 per cent of people aged 18 and up have now received three vaccine doses. That figure has risen by less than seven percentage points in a month — it stood at 57.1 per cent on February 23.
