The higher the COVID-19 immunization level in a given population, the lower the incidence in unvaccinated adolescents under 16 years of age. In other words, adult vaccinations have a positive effect on protecting children against coronavirus. This is the result of research by Israeli scientists.
- Israel is the benchmark for many countries when it comes to vaccination rates against COVID-19
- In April, it was announced there that vaccination had achieved herd immunity

Mass vaccination also protects the unvaccinated
The high level of vaccination of the population also contributes to the decline in the number of cases in the unvaccinated part of the society. What doctors and virologists constantly talk about was confirmed by research from Israel.
Researchers at the Technion-Israel Institute of Technology in Haifa conducted a study that looked at the vaccination rate and COVID-19 test results from 177 regions in Israel. The research results are published in the latest issue of the prestigious journal Nature.
The study covered a total of 1,37 million people who received the first dose of the Pfizer / BioNTech vaccine between December 9, 2020 and March 9, 2021. Regions were taken into account in which the percentage of cases by March 9 did not exceed 10% . to exclude places where herd immunity could be affected by a past infection.
Researchers looked at how the percentage of positive COVID-19 tests was changing in each of these regions among children under 16, a group that was not yet vaccinated at the time.

For each of the 177 groups, the percentage of vaccinated people aged 16-50 who received one dose of the preparation was calculated. The vaccination effect was checked 28 days after vaccination to take into account the full effects of vaccination
Adult vaccinations protect children
The percentage of positive COVID-19 tests among the unvaccinated group of people up to 16 years of age was then calculated.
As it turned out? The relationship between the level of vaccination in a given population and the level of disease is very clear. 20 percent more vaccinated in adults, it translated into a two-fold decrease in the incidence of unvaccinated adolescents.
The results did not take into account natural immunity, but this is further evidence that the level of vaccination has a colossal impact on the rate of suppression of the coronavirus pandemic.

«These results provide evidence that vaccination not only protects those who have been vaccinated but also provides cross-protection to unvaccinated people in the community.“- wrote the authors of the broadcast. “While the observed vaccine-related protection of the unvaccinated population is satisfactory, more research is needed to understand if and how vaccination campaigns can support herd immunity and disease control.”
Israel began mass vaccinations on December 19, 2021. In early April, it was announced that 62 percent had received the first dose of the vaccine. citizens and herd immunity has been achieved. It was then that the restrictions related to the coronavirus pandemic began to be lifted.
