BOOSTERS jabs slash the risk of getting Covid by two thirds and have helped see cases fall after record levels in October.
Mass testing shows people given a third dose of the vaccine are 62 per cent less likely to get Covid than the double-jabbed.
Professor Paul Elliott, from Imperial College London, said: “Within 14 days of having had a third dose, the risk of infection is reduced by two thirds – so this is very, very effective.”
He was speaking after a study led by the college tested 100,000 people at random and gave dramatic real-world proof of how well the boosters work.
In total, 13.5million people have already had the third dose and millions more will be eligible in the coming weeks.
When compared to unvaccinated people, the boosters slash infection risk by 80 per cent, according to figures from the Office for National Statistics.
Prof Elliott said: “We had a large rise from September through to October and the peak occurred around the 20th or 21st of October.
“Then there was this quite rapid decrease that coincided with the half-term, and the trend was really being driven by young people.
“The huge rollout of the vaccine has been fantastically impressive and we’ve shown the positive effects of the booster.”
Another 38,263 cases were announced yesterday, down three per cent in a week, along with 201 deaths.
