An analysis of data from a significant number of 200,000 patients over the age of 60, Klalit, Israel’s largest health insurance fund, showed that
two weeks after the first dose, there were a third fewer elderly people among the newly infected, and not just the vaccine, the number of illnesses decreased.
Israeli research shows that
the coronavirus vaccine made by Pfizer not only protects vaccinees from COVID-19 infection, but also helps prevent people who have already been vaccinated from passing the disease on to others.
The main question of the research was whether the vaccine only prevents the vaccine from becoming ill or whether the vaccine slows down the transmission of the virus. Data from the identified infected individuals showed that vaccination for 5–12 days did not affect overall infection rates among the observed 200,000 over 60 years of age, but by day 13 there was a slight decrease and from day 14 onwards their infection decreased by a third. projected to an age group.
This is the first evidence that the Pfizer vaccine not only prevents the vaccinated person from becoming infected, but also prevents the exposed person from passing the virus on to others.
Professor Ran Balicer, head of Klalit’s research department, said the results, although preliminary, were “very encouraging.” “It is important to keep in mind that these observations do not show that vaccination provides complete protection against the disease,” he warned, however, with further caution. “Therefore, vaccinees must continue to be careful, wear a face mask, and follow public health guidelines to protect those around them,” he added.
Balicer told ynet that experts hope it will be demonstrated in the coming weeks whether the vaccination will also help reduce severe COVID cases and hospitalization of infected people.
Vaccination should be repeated after three weeks according to the instructions of the pharmaceutical company, and only one week after the administration of the second dose of the vaccine, about 95 percent protection for vaccinees is promised.
Israel was the world leader in coronavirus vaccination relative to the proportion of the population, and on December 20, 2020, it began vaccinating health care professionals and those at 60 years of age at particular risk. To date, the first of two doses of the vaccine has been given to almost 2 million people, and the second dose has already been started.
