LONDON - A major study has found that three doses of the same Covid vaccine or a combination of jabs work equally well in preventing infections.
A global analysis of data from more than 100m people has confirmed that the number of doses is the key to boosting immunity rather than jab combinations.
Meanwhile, Paul Hunter, a professor of medicine at the University of East Anglia, has told The Guardian that Covid infection rates “are not going to get down to very low numbers again in our lifetimes”.
