Australia shortens wait time for Covid-19 booster doses as Omicron cases rise

Australia said on Sunday it will shorten the wait time for people to receive Covid-19 booster vaccines following a rise in cases of the Omicron variant.

Australia had previously said it would offer a Covid-19 booster to everyone over 18 and who had their second dose of the vaccine six months prior.

But with rising cases of the Omicron variant, Australia's Health Minister Greg Hunt said the time interval will be shortened to five months after the second dose.

"A booster dose, five or more months after the second dose, will make sure that the protection from the primary course is even stronger and longer lasting and should help prevent spread of the virus," Hunt said in an emailed statement.

"Data from Israel shows boosters supporting reductions in the rate of infection in eligible age groups, severe disease in those aged over 40 years and deaths in those over 60 years."

Still, Australia said on Saturday it found 1,753 Covid-19 cases in the past 24 hours, up about 3 per cent in the last week and the highest daily total since October 29.
