After the researchers adjusted for factors such as age, they found that people who received two doses of the vaccine were 59% less likely to be infected with the highly contagious delta variant.
“These findings confirm our previous data showing that both doses of the vaccine offer good protection against infection,” Paul Elliott, director of the REACT program of Imperial’s School of Public Health, said in a statement. The researchers did not elaborate on the effectiveness of any particular vaccine.
The new study also found that people who vaccinated on average have a lower viral load, meaning they are likely to spread less virus and be less infectious than people who are not vaccinated.
“The delta variant is known to be highly contagious, and our data found little immunity in fully vaccinated individuals,” Steven Riley, professor of infectious disease dynamics at Imperial College London, said in a statement.

Currently, young people aged 13 to 24 have the highest infection rates, and people 75 years and older have the lowest infection rates. About 50% of infections occur in people aged 5 to 24, even though they make up only a quarter of the population, Riley told Reuters.
UK Secretary of Health and Social Care Sajid Javid said in a statement that people who have not received the vaccine for injection vaccine so that they are safe at work.
