A study of nearly 100,000 people in the UK reveals that the infection rate of the Delta strain in the fully vaccinated population has dropped by 2/3

According to a report from the British Government Network on the 4th, REACT-1, one of the UK's national new coronavirus infection tracking studies, announced the latest results, saying that compared with unvaccinated people, the new crown virus infection rate of people who have completed vaccination is 1/3 of the former.

The REACT-1 project is jointly carried out by Imperial College and Ipsos Mori Poll.

From June 24 to July 12 this year, the researchers received a total of 98,233 samples sent back by participants

Nucleic acid test results showed that during this period, the participants’ new coronavirus infection rate was 0.

According to information from Imperial College London, after adjusting the data based on factors such as age and gender, researchers estimate that the vaccine is 50%-60% effective in preventing new coronavirus infections among 18-64 year-olds

Nadim Zahavi, the head of the deployment of the new crown pneumonia vaccine in the United Kingdom, said that this result shows that the vaccination has a positive effect.

The REACT project leader and professor at Imperial College Paul Elliott added that these data also show that no vaccine can be 100% effective, and people who are fully vaccinated can also be infected

Data from the UK Department of Health (PHE) shows that the effectiveness of two doses of vaccine against the new coronavirus is more than 90%
