Unvaccinated people are 16 times more likely to end up in intensive care units or die from COVID-19, Australia’s New South Wales state said in a report.

The data from New South Wales (NSW) health department out late on Monday showed only 11 percent of people out of 412 who died from the Delta outbreak over four months through early October were fully vaccinated. The average age of those deaths was 82.

Only around 3 percent of people in intensive care units had two doses, while more than 63 percent 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 hospitalization,” NSW Chief Health Officer Kerry Chant said in a statement.

The report’s findings were in line with data from the US Centers 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.
