Lower risk of Covid-19
FULLY-VACCINATED people in England were one-third as likely to test positive for Covid-19, compared to those unvaccinated, according to an ongoing survey of the population released last Wednesday.
The latest findings, from a long-running study by scientists at Imperial College London and market research company Ipsos Mori, were based on 98,233 swabs taken between June 24 and July 12.
They found that one in 160 people were infected with the SARS-COV-2 virus, with a prevalence rate of 1.21% for unvaccinated respondents and 0.4% for those fully jabbed.
The study also found that fully-vaccinated people may be less likely to pass on the virus to others than those who have not received a vaccine.
However, officials and scientists in the United Kingdom have urged caution after the UK government eased all virus curbs in England on July 19, including the legal requirement to wear face masks in certain indoor settings. A US government document leaked last week warned that infections among fully-vaccinated people are not as rare as previously thought and that such cases are highly contagious.
Dr Paul Elliott, a professor at Imperial’s School of Public Health and director of the survey programme, said the 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% 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.”
Covid-19 cases registered daily by UK’S health ministry have declined since the relaxation of rules, while population surveys have suggested they may still be rising, albeit at a slower rate.
The trend has surprised experts and officials, who predicted a surge in new infections.
The Imperial-ipsos study – covering the period up to July 12 – showed even then that cases were climbing more gradually than during the previous month.
