Having both jabs sees risk of catching Covid plummet, study confirms

Chance of catching Covid after having two vaccine jabs is just one in 22,500, new study shows

  • Double vaccinated population have significantly lower risk of getting Covid-19
  • ZOE study says your chance of catching virus drops to 1/22,500 after both jabs
  • Officials say vaccines have saved 14,000 lives and 42,000 hospitalisations so far
  • More than half of adults in the UK have now received both of their Covid shots

Having two vaccinations slashes the chances of getting Covid to just one in 22,500, it was revealed yesterday.

Those who are fully vaccinated are three times less likely than those who have had only had one dose of the jab, according to a study. 

The risk of catching Covid rises to one in 2,908 in those who are unvaccinated.

The study, based on data gathered from more than a million users of the ZOE Covid Symptom Study app, is yet more evidence that vaccines have broken the link between cases, hospitalisations and deaths.

Officials estimate some 14,000 lives have already been saved and 42,000 hospitalisations prevented by the vaccine programme – which has seen nearly 70million doses dished out.

Almost 55 per cent of adults are now fully vaccinated – with some 28,857,102 now protected by two doses.

The symptom tracking app found one in 543 people in the UK currently have symptomatic Covid, with cases higher and increasing faster in the younger unvaccinated population. 

It put the R-rate – the rate at which it spreads – at 1.3 nationally, but stressed much of the transmission was in the young.

The study, run by Professor Tim Spector’s ZOE Covid Symptom Study app, said having two vaccinations slashes the chances of getting Covid to just one in 22,500

Professor Tim Spector, an epidemiologist at King’s College, runs the ZOE Covid study. 

His app showed the number of Britons falling ill with Covid has more than doubled in a week with an estimated 11,908 across the UK catching the virus each day.

But because rising case numbers were mainly among the young, far fewer people were becoming seriously ill. 

He said: ‘It’s clear that this is an epidemic among the unvaccinated and partially vaccinated.’

Separate data showed that while cases of the new Indian/Delta variant are rising across the country, hospitalisations remain more than 18 times lower than at the peak in January.

Public Health England (PHE) figures show case rates in England have risen among almost all age groups, with the highest among 20 to 29-year-olds.

Officials estimate some 14,000 lives have already been saved and 42,000 hospitalisations prevented by the vaccine programme – which has seen nearly 70million doses dished out

Fewer than seven in 100,000 over-80s have picked up the new strain, showing the effectiveness of vaccines in helping to prevent infections and serious illness.

Deaths had also fallen again in the week ending June 6, the PHE surveillance report states.

And hospitalisations remain a fraction of what they were at the peak with 1.09 per 100,000 people needing treatment compared to 35 per 100,000 in January.

Dr Jenny Harries, the chief executive of the newly created UK Health Security Agency, said that modelling data suggests there will be a further rise in Covid-19 cases in the coming weeks.

She said that data suggests that those in the older age groups, aged 60 and above, are not getting ill with Covid-19 because they have had both doses of the Covid-19 jab.

She added that those appearing in hospital are either unvaccinated or those who have had a single dose of a Covid-19 jab.

However, she stressed it was still too early to make a decision on ending lockdown on June 21 and it will take another week before a clearer picture emerges.

Speaking at a Royal Society of Medicine webinar, she said: ‘Cases are rising, I think that is becoming clearer and modelling does suggest that we would start to see a further rise, not necessarily immediately but in coming weeks.’

She added: ‘Because of the rise in hospitalisations, and the risk that there may be a wider spread of the Delta (Indian) variant, it is really primarily important for saving lives that the older individuals who are more at risk, who have not had first and second vaccinations, maximally get vaccinated.’
