A - produced by modellers at the University of Warwick - which was published this week says: "Only vaccines that offer high infection-blocking efficacy with high uptake in the general population allow relaxation of non-pharmaceutical interventions without a huge surge in deaths."
The authors said it is important to continue monitoring the vaccine rollout in the UK and other countries.
The paper continues: "While the novel vaccines against SARS-CoV-2 offer a potential exit strategy for this outbreak, this is highly contingent on the infection-blocking (or transmission-blocking) action of the vaccine and the population uptake."
INFECTION RATE
Dr Sam Moore, one of the authors of the research, said vaccines need to prove "very high" infection blocking to drive the infection rate down.
He told The Telegraph: "If we get very high infection blocking then this could almost be what delivers us from it, but it would have to be very high.
"Even vaccines with 85 per cent infection blocking are insufficient to drive 'R' below one on their own."
Vaccine minister Nadhim Zahawi, who said he had not read the Warwick paper, added: "We're probably another four weeks away from getting some of that data back but it should be able to then allow us to make plans… we'll be able to see the impact of vaccines on transmission and also on hospitalisation and serious infection."
As inoculations rack up, early data shows the crisis is easing and the number of people testing positive is already dropping, experts have said.
