SYDNEY (REUTERS) - Unvaccinated people are 16 times more likely to end up in intensive care units or die from Covid-19, Australia's New South Wales (NSW) state said in a report, with officials urging people to get inoculated as the country begins to live with the coronavirus.

The data from NSW's health department out late on Monday (Nov 8) showed that only 11 per cent of people out of 412 who died from the Delta outbreak over the four months till early October were fully vaccinated. The average age of those deaths was 82.

Only around 3 per cent of people in intensive care units had two doses, while more than 63 per cent of the 61,800 cases detected between June 16 and Oct 7 were unvaccinated.

"Young people with two doses of a vaccine experienced lower rates of infection and almost no serious disease, while those unvaccinated in this age group were at greater risk of developing Covid-19 and needing hospitalisation," NSW chief health officer Kerry Chant said in a statement.

The report's findings were in line with data from the United States Centres for Disease Control and Prevention, which said in September that unvaccinated individuals were 11 times more likely to die from Covid-19 than those who were fully vaccinated.

Australia had stayed largely virus-free this year until an outbreak of the highly infectious Delta variant that started in June led to a months-long lockdown in Sydney and Melbourne, its largest cities, and the national capital of Canberra.

The virus-hit cities have been easing tough restrictions after passing vaccination targets of up to 80 per cent.

The roll-out in NSW, home to Sydney, appears to have plateaued after first-dose coverage reached almost 94 per cent of the population above 16.

More than half of Australia's total deaths of 1,841 and about 87 per cent of its nearly 183,000 infections in the pandemic are due to the Delta strain of the coronavirus.

However, the death rate is lower than last year's, thanks to a surge in vaccinations since July.
