The benefits of the new crown vaccine high vaccination rate: protect those who have been vaccinated, but also protect those who have not been vaccinated

　　The latest research confirms the benefits of the new crown vaccine's high vaccination rate

　　Not only protect the vaccinated, but also protect the unvaccinated

　　Science and Technology Daily, Beijing, June 15 (Reporter Zhang Mengran) An immunological study recently published in the British journal Nature Medicine found that the high vaccination rate of the new crown pneumonia vaccine and the low infection rate of the new crown virus in people aged 16 and under related.

This result comes from the researchers’ analysis of vaccination records and test results in 177 communities in different geographic locations in Israel from December 6, 2020 to March 9, 2021. It shows that vaccination not only protects the vaccinated, but also protects Those who have not been vaccinated.

　　Clinical trials and vaccination plans show that the new crown vaccine is effective in preventing infection and disease at the individual and community levels.

However, some voices believe that vaccination may lead to changes in human behavior. For example, if people who have been vaccinated do not pay attention to maintaining social distancing, or do not actively isolate themselves after contact with new crown patients, it will increase infectivity.

　　Among the countries vaccinated in the world, Israel is leading the way. It started vaccination on December 19, 2020 and covered nearly 50% of the population within 9 weeks. As of now, nearly 80% of Israeli adults have completed the vaccination. Vaccination, the country has not yet carried out vaccination work for children and adolescents under 16 years of age.

　　In order to clarify whether vaccination can reduce the spread of the new crown virus in unvaccinated individuals at the group level, Roy Zishni, a scientist at the Technion-Israel Institute of Technology, and Tal Patalon, a researcher at Maccabitech, the R&D and Innovation Department of the Israeli Health Organization, and their colleagues Colleagues, this time researched 177 communities with different geographic locations and different vaccination rates (a total of 1.37 million people received the first dose), as well as a group of unvaccinated groups under the age of 16 with no vaccine available.

　　The researchers counted the changes in the number of new crown positives in each community at regular intervals.

They found that, on average, for every 20% increase in the number of vaccinated people in a community, the number of people who have not been vaccinated in the same community will have a downward trend in the number of people who have not been vaccinated.

　　The research team reminded that their research results did not consider the population's natural immunity to the new coronavirus.

　　They concluded that although it is exciting to see vaccine-related protection in unvaccinated people, further research is needed to understand how the vaccination program can help achieve herd immunity and eliminate disease.
