Studies have shown that the higher the level of vaccination against COVID-19, the lower the rate of SARS-CoV-2 infection in a group of unvaccinated people under the age of 16. Natural medicineBased on an analysis of vaccination records and test results in 177 geographically distinct communities in Israel from December 6, 2020 to March 9, 2021, the findings show that vaccination against COVID-19 is a vaccine. It has been shown to help protect both those who have been vaccinated and those who have not.

Clinical trials and vaccination campaigns by Pfizer-BioNTech vaccine Countermeasures against COVID-19 are very effective in preventing infections and illnesses at the individual and community level. However, it has also been suggested that vaccination may increase infections due to changes in human behavior. For example, vaccinated people may not be very conscious of keeping a social distance or may not quarantine after contact with a person infected with COVID-19.

The vaccination rollout in Israel began on December 19, 2020, with the first dose of the vaccine given to nearly 50% of people. population Within 9 weeks.Determining whether SARS-CoV-2 infection is reduced among unvaccinated individuals Population level, Roy Kishony, Tal Patalon, and colleagues have 177 geographically distinct communities with different vaccination rates (equivalent to a total of 1.37 million first-time vaccinations of the Pfizer-BioNTech vaccine) and unvaccinated persons under the age of 16. I paid attention to the cohort of. The age at which the vaccine was not yet available. The authors evaluated changes in the number of positive COVID-19 tests within each community at regular time intervals. On average, for every 20% increase in the number of vaccinated people in a particular population, the number of people who are not vaccinated in the same community is about positive on the SARS-CoV-2 test. We found that it was reduced by half.

The authors warn that their findings do not take into account the potential for spontaneously acquired immunity to SARS-CoV-2. They reassure the observed vaccine-related protection of the unvaccinated population. However, he concludes that further research is needed to understand whether and how vaccination campaigns support the prospect of mass immunity and disease eradication.
