Covid vaccines saved thousands of lives

Australia’s Covid-19 vaccination campaign likely prevented almost 18,000 deaths in NSW alone between 2021 and 2022, with the mortality rate in unvaccinated individuals almost eight times higher than those who were fully vaccinated, new research has found.

Research from RMIT University and Monash University found Australia’s Covid-19 vaccination campaign likely prevented the death of 17,760 people aged over 50 in NSW between August 2021 and July 2022.

University of South Australia chair of biostatistics Professor Adrian Esterman said the researchers, who focused on those aged 50 and over and used data from NSW since “access to full official Australian government datasets was not possible”, found that unvaccinated individuals had 7.7 times the Covid-19 death rate, compared with those with two or more doses.

“This increased to 11.2 times the death rate when comparing the unvaccinated to those who had one or more booster shots,” Professor Esterman said.

“In the total absence of a vaccination program, they estimated that over the 48-week period, there would have been 21,250 Covid-related deaths – six times the actual rate.

“One mistake vaccine sceptics keep bringing up is that the majority of Covid-related deaths are in those who have been vaccinated – therefore the vaccines do not work, or even cause death.

“The authors rightly point out that a fairer comparison is to look at the death rate in those unvaccinated, compared to those vaccinated, which immediately shows how important the vaccination program has been in preventing Covid-19-associated deaths.”
