A new study by researchers at Imperial College London found that those with both rounds of a coronavirus vaccine are half as likely to be infected with the virus than those who have not been vaccinated. The results of the research come as case numbers continue to drop across much of the UK despite the prevalence of the Delta variant.
The study was based on data from 98,000 swab tests taken between June 24 and July 12 this year.
It demonstrated fully vaccinated individuals were less likely to develop a serious infection, as those who were fully vaccinated showed smaller amounts of the virus in their samples.
This also makes the fully vaxxed less likely to pass it on to others.
The highest infection prevalence was found in the younger generations, with those aged 13 to 24 recording 1.56 percent, in comparison with those aged 75-plus at 0.17 percent.
Young people are still receiving vaccinations across the UK, with the go-ahead now given to vaccinate 16 and 17-year-olds.
Unvaccinated young people are currently driving infection numbers in the UK, a trend that is also mirrored in the USA, which is struggling to combat the highly infectious Delta variant.
The researchers also estimated current vaccines are 49 percent effective at preventing infection, sleepwell mattress price list in visakhapatnam in line with other recent data with is dramatically lower than previous estimates.
The reduced effectiveness was addressed in the study, with scientists saying the “development of vaccine against Delta may be warranted” as the spread continues.
What are the odds of being infected with Covid?
If you are fully vaccinated, the odds of being infected with the disease if you come into contact with someone who is infected and contagious, is one in 26, according to the researchers.
If you are not vaccinated, the chance of being infected is one in 13.
Professor Paul Elliott, director of the REACT programme from Imperial’s School of Public Health, said: “These findings confirm our previous data showing that both doses of a vaccine offer good protection against getting infected.

“However we can also see that there is still a risk of infection, as no vaccine is 100 percent effective, and we know that some double vaccinated people can still become ill from the virus.
“So even with the easing of restrictions, we should still act with caution to help protect one another and curb the rate of infections.”
Professor Steven Riley, Professor of Infectious Disease Dynamics at Imperial, said: “The Delta variant is known to be highly infectious, and as a result, we can see from our data and others’ that breakthrough infections are happening in fully vaccinated people.
“We need to better understand how infectious fully vaccinated people who become infected are, as this will help to better predict the situation in the coming months, and our findings are contributing to a more comprehensive picture of this.”
Health and Social Care Secretary Sajid Javid said: “Our vaccination rollout is building a wall of defence that means we can carefully ease restrictions and get back to the things we love, but we need to be cautious as we learn to live with this virus.
“Today’s report shows the importance of taking personal responsibility by self-isolating if you are contact traced, getting tested if you have symptoms and wearing face coverings where appropriate.
“I urge anyone who has yet to receive a vaccine to get jabbed and take up both doses – the vaccines are safe and they are working.”
