The research published yesterday – focusing on prevention of severe Covid-19 and death, not infection – looked at 22 million people over 50 and found those who had received jabs were 90 per cent less likely to be hospitalised or die.

The results confirm observations from the US, Britain and Israel, but researchers say it is the largest study of its kind so far.
