Mass vaccination dramatically reduced the number of new coronavirus infections in Israel. This was especially true for the elderly, who were vaccinated in the first place.

A study by Israeli doctors confirms the effectiveness of the national mass vaccination strategy. According to scientists, the number of new SARS-CoV-2 infections among elderly and young Israelis decreased sharply in February-March 2021. The results of the study were published in the scientific journal Nature Medicine.

"Two months after the start of vaccination, the number of infections decreased by 77%, and severe cases of COVID-19 - by 67%. This trend is especially strong appeared among the elderly, who are most vulnerable to infection and were the first to be vaccinated," the researchers write.

Israel was one of the first countries in the world to begin full vaccination of the population against COVID-19 using a vaccine developed by Pfizer and BioNTech. It started on December 20, 2020. On January 10, the vaccinated began to receive a second dose. At the moment, more than 5.35 million people received the first dose, more than 4.97 million people received the second dose, that is, more than half of the country's population.

As the vaccination progressed, authorities gradually lifted restrictions to contain the spread of SARS-CoV-2. In February, residents of the country were allowed to move away from home for more than a kilometer, and expanded the work of shopping centers and street shops. In March, restaurants, theaters and stadiums were allowed to open, and on April 18, the authorities lifted the mandatory wearing of masks outdoors.

Israeli doctors under the guidance of a professor at the Institute of Science. Weizmann Eran Sehgal decided to test how successful the Israeli vaccination strategy was. To do this, the authors studied how it took place in different regions of Israel and how the incidence rate changed over the next few weeks among those age groups that received the first and second doses of the vaccine.

These observations showed that in late February and early March, the incidence rate, the frequency of hospitalization and admission to intensive care among Israelis of all ages decreased significantly. This is especially true for people aged 60 to 90 years, as well as those regions where vaccination was carried out somewhat earlier than in other areas of Israel.

Therefore, Sehgal and his colleagues believe that a mass vaccination strategy could drastically slow the spread of the coronavirus. They note that in the poorest and most disadvantaged regions of the country, vaccination was far from optimal, despite the same level of access to vaccines.

The authors of the study hope that further observations will help to assess how vaccine resistance will affect the epidemiological situation in the country, and to choose the best methods to increase the popularity of vaccines in the poorest regions Israel.
