Covid infection rates three times lower for people given two doses of vaccine, research shows

Coronavirus infection rates are three times lower for those who have received two doses of the vaccine, new research has shown.

In people aged 64 or younger, the prevalence of infection among those who had received two doses of the vaccine was 0.35% compared to 1.15% among those who had not received any vaccine.

Data from Public Health England shows that having both doses of a Covid-19 vaccine can reduce symptomatic infection by almost 80%. The infection rate in Wales rose to 109.6 cases per 100,000 population based on the seven days between June 26 and July 2 – from 103.2 on Tuesday. Learn more about the latest figures for Wales.

The new data, covering the period June 24 to July 5, also shows that infections in England have quadrupled from 0.15% to 0.59% since the last React-1 report which covered May 20 to June 7. .

Data shows that one in 170 people is infected and a recent doubling time of six days.

More than 47,000 volunteers returned PCR tests to England between June 24 and July 5 to examine levels of Covid-19 in the general population via React-1, one of the country’s largest studies of infections with Covid-19 in England.

There were substantial increases in all age groups under 75, and especially younger, with the highest prevalence among 13 to 17 and 18 to 24 year olds. Infections have increased in all regions with the largest increase in London.

Professor Paul Elliott, director of the React program at Imperial’s School of Public Health, said: “Despite the successful roll-out of the vaccination program, we are still seeing a rapid growth in infections, especially among young people. However, it is It is encouraging to see a decrease in infections and prevalence among people who have received both doses of a vaccine, so it is essential that as many people as possible receive both doses of vaccine when offered.

Kelly Beaver, general manager of public affairs at Ipsos Mori, said: “It seems very likely that the prevalence of Covid-19 will continue to rise as the country unlocks further, but there are encouraging signs that the program vaccination works. These results reiterate the importance of getting vaccinated. We are very grateful to all research participants across England for their contribution to this study. “

English Health Secretary Sajid Javid admitted cases would “inevitably” increase as the British government eases restrictions in England.

Boris Johnson previously announced that all current legal limits on social interactions and restrictions on major events, performances and life events will be lifted at the next stage of the roadmap – which will likely take place on July 19. . Face covers will also no longer be mandatory indoors, although guidance will suggest where people might choose to wear one.

Almost two-thirds of adults – 64% – have received both doses and therefore enjoy the most comprehensive protection. in offer.

“I urge everyone to receive their first and second doses when prompted, as each injection helps curb transmission and serious illness. The small number of people who double inject and experience symptoms should continue. to get tested so that we can all play our part in stopping the spread of this terrible virus. “
