Having two vaccinations reduces the chance of getting Covid to just one in 22,500, it was revealed yesterday.
Those who have been fully vaccinated are three times less likely than those who have had just one dose of the jab, according to one study.
The risk of contracting Covid rises to one in 2,908 in those who have not been vaccinated.
The study, based on data collected from more than a million users of the ZOE Covid Symptom Study app, is further evidence that vaccines have broken the link between cases, hospitalizations and deaths.
Officials estimate that the vaccine program has already saved some 14,000 lives and prevented 42,000 hospitalizations – nearly 70 million doses have been distributed.
Nearly 55 percent of adults are now fully vaccinated – with about 28,857,102 now protected by two doses.
The symptom tracking app found that one in 543 people in the UK currently have symptomatic Covid, with cases rising higher and faster in the younger unvaccinated population.
It set the R-rate — the rate at which it spreads — at 1.3 nationally, but emphasized that much of the transmission was in young people.
The study, conducted by Professor Tim Spector’s ZOE Covid Symptom Study app, said having two vaccinations reduces the chance of Covid to just one in 22,500.
The number of people getting sick with Covid has more than doubled in a week, a symptom-tracking study warned today amid the rapid spread of the Indian variant in the UK
Disease rises significantly faster in 20- to 29-year-olds than in vaccinated older age groups. There were more than 400 symptomatic cases per 100,000 people in the cohort compared to less than 50 in those over 60
There are currently 1,917 vaccinated people getting sick with the virus, compared to 9,991 unvaccinated people. But cases are on the rise in both groups, with 89 percent more symptomatic cases in people week-over-week, even after being stung.
Meanwhile, Test and Trace figures released today showed the number of positive concerns in England rose nearly 45 percent last week. More than 25,000 people sampled in the seven-day ban ending June 2 had Covid, up from 17,000 the week before
The increase in Test and Trace figures came despite approximately 850,000 fewer tests being performed compared to the week before
Professor Tim Spector, an epidemiologist at King’s College, is leading the ZOE Covid study.
His app showed that the number of Britons getting sick from Covid has more than doubled in a week, with an estimated 11,908 across the UK contracting the virus every day.
But because the rising number of cases mainly occurred among young people, far fewer people became seriously ill.
He said: “Obviously this is an epidemic among unvaccinated and partially vaccinated people.”
Separate data showed that while the number of cases of the new Indian/Delta variant is increasing across the country, hospitalizations remain more than 18 times lower than at the peak in January.
Figures from Public Health England (PHE) show that the number of cases in England has risen among almost all age groups, with the highest among those aged 20 to 29.
Officials estimate that the vaccine program has already saved some 14,000 lives and prevented 42,000 hospitalizations – nearly 70 million doses distributed
Fewer than seven in 100,000 people over 80 have picked up the new strain, demonstrating the effectiveness of vaccines in helping prevent infections and serious illness.
Deaths had also fallen again in the week ending June 6, the PHE surveillance report said.
And hospital admissions remain a fraction of what they were at their peak at 1.09 per 100,000 people needing treatment, compared with 35 per 100,000 in January.
dr. Jenny Harries, the chief executive of the newly created UK Health Security Agency, said model data suggests there will be a further rise in Covid-19 cases in the coming weeks.
She said data suggests that those in the older age groups, aged 60 and over, do not get sick with Covid-19 because they have had both doses of the Covid-19 shot.
She added that those who show up in hospital are unvaccinated or have had a single dose of a Covid-19 shot.
However, she stressed that it is too early to make a decision about ending the lockdown on June 21 and that it will be another week before a clearer picture emerges.
Speaking to a Royal Society of Medicine webinar, she said: “The number of cases is increasing. I think that is becoming clearer and modeling suggests we would see a further increase, not necessarily immediately, but in the coming weeks.”
She added: ‘Because of the increase in hospitalizations and the risk that there is a greater spread of the Delta (Indian) variant, it is really especially important to save lives that the older persons who are more at risk, who are not first and foremost had second vaccinations, maximum vaccination.’
