Since March 2021, 97.5% of reported COVID-19 cases in NSW are in unvaccinated people. COVID-19 vaccines are effective at protecting people against the Delta strain, which is twice as infectious as the original strain.
NSW recorded 56,240 COVID-19 cases1 from 1 March to 30 September 2021 (74.8% of Australia’s total cases) and only 3%2 of locally acquired cases were fully vaccinated. Over 58% of locally acquired cases reported no vaccination at all.
Unvaccinated people are at the greatest risk from the Delta variant. The Delta variant is more than twice as contagious, has nearly double the increased risk of needing hospital care compared to the Alpha variant and is more likely to require infected people to be admitted to hospital, including to intensive care, compared to other variants.5
Evidence from around the world shows that two doses of a COVID-19 vaccine are effective against the Delta Variant and offers the best form of protection.5
A recent study carried out in Los Angeles County, found unvaccinated people are almost 30 times more likely to be hospitalised by COVID-19.
The research, published on the CDC website, tracked infections from 1 May to 25 July this year, a period that coincided with the Delta variant becoming the dominant strain in the US.
Of 43,127 COVID-19 cases, 10,895 (25.3%) were identified in fully vaccinated residents, 1431 (3.3%) were recorded among the partially vaccinated, while 30,801 cases (71.4%) were found among unvaccinated people.9
Once adjusted for age, results indicated that rates of hospitalisation were 29.2 times higher among the unvaccinated compared to the vaccinated.9
Two doses of a vaccine can make a critical difference by:
- Reducing the chance you will be infected with COVID-19 by around 60% to 80%.
- Providing around 90% protection against hospital admission or death from COVID-19 if you are infected.
- Significantly reducing the overall spread of COVID-19 to others.5
Professor Dimity Pond, an honorary professor of general practice at the University of Newcastle, emphasised the importance of vaccination.8
“That’s the kind of pattern that we’ve been seeing where the deaths are very largely in people who aren’t vaccinated. It’s really hard data. It can’t be interpreted in any way other than vaccination means that you’re less likely to die.”
