According to an ongoing population survey released on Wednesday, fully vaccinated people in England were one-third as likely to test positive for Covid-19.
The latest findings were based on 98,233 swabs taken between June 24 and July 12 as part of a long-running study by Imperial College London academics and market research firm Ipsos MORI.
They discovered that one out of every 160 people was infected with coronavirus, with a prevalence rate of 1.21 percent among unprotected people and 0.40 percent among those who had been fully vaccinated.
The study also discovered that those who have been twice vaccinated are less likely to spread the virus to others than those who have not been immunized.
Officials and experts in the United Kingdom, on the other hand, have counseled caution after the government of England relaxed all virus restrictions on July 19, including the legal obligation to wear masks in certain indoor situations.
Infections among fully vaccinated people are not as rare as previously thought, according to a US government paper published last week, and such instances are highly contagious.
The findings “support our earlier data demonstrating that two doses of a vaccine offer good protection against getting sick,” said Paul Elliott, a professor at Imperial College’s School of Public Health and the survey’s director.
“However, we can see that there is still a danger of infection, as no vaccine is 100% effective, and we know that some people who have been twice vaccinated can still get sick from the virus.”
“As a result, even with the loosening of restrictions, we should use prudence to help protect one another and reduce infection rates.”
Covid-19 cases reported to the UK’s health ministry on a daily basis have decreased after the limits were relaxed, while demographic surveys suggest they are still rising, albeit at a lesser rate.
Experts and officials were astonished by the pattern, which they thought would result in an increase in new illnesses.
The Imperial-Ipsos study, which covered the period up to July 12, found that cases were progressively increasing even then, compared to the previous month.
