Experts are renewing calls for people to get their COVID-19 booster dose in the wake of rising infections and hospitalisations.
Chief Medical Officer Paul Kelly says there are continuing reinfections from the Omicron variant that are escaping immune responses bolstered by vaccinations.
"We are seeing reinfection, we know that Omicron, having had a previous dose of one of the other variants of COVID-19, did escape that immune protection from both a previous dose and from only two doses of vaccine," Professor Kelly told Sky News.
