Coronavirus Vaccine: The research-- focusing on prevention of severe Covid and death, not infection -- looked at 22 million people over 50.
Vaccination is highly effective at preventing severe cases of Covid-19, even against the Delta variant, a vast study in France has shown.
The research published Monday -- focusing on prevention of severe Covid and death, not infection -- looked at 22 million people over 50 and found those who had received jabs were 90 percent less likely to be hospitalised or die.
The results confirm observations from the US, the UK and Israel, but researchers say it is the largest study of its kind so far.
Looking at data collected starting in December 2020, when France launched its jab campaign, the researchers compared the outcomes of 11 million vaccinated people with 11 million unvaccinated subjects.
