Doctors call for vaccination with a booster dose. It prolongs the resistance to SARS-CoV-2, which declines over time, protecting against severe COVID-19 and death. While we do not know yet how long this protection lasts, we do know to what extent it protects against death. The results of analyzes carried out in Israel leave no illusions.
- The most important task of vaccines is to prevent severe disease and thus prevent death. Due to the decline in protection over time, booster immunizations are necessary
- A team of scientists decided to investigate to what extent the Pfizer-BioNTech booster reduces the risk of dying from COVID-19
- The data of over 800 people, of which 90 percent. received a booster dose
- It turned out that after receiving the third dose, the risk of death was lower by 90%. in relation to people who did not receive a booster

The recommendation of boosters does not mean a failure of the existing vaccines
The most important task of vaccines is to prevent severe disease and therefore death. We also know that, unfortunately, the immunity obtained after the primary COVID-19 vaccination course declines over time. Hence, it is so important to bring it back to the appropriate level, i.e. to take a booster dose. The more so because the Omikron super variant has appeared and it is possible that more variants will appear.

It is worth emphasizing that the recommendation of boosters does not mean a failure of the existing SARS-CoV-2 vaccines. The fact that they may be needed has been said since vaccination began. It’s also worth remembering that although the pandemic has been going on for two years, the world is still learning about the coronavirus and COVID-19.
The authors of a study published in late December in the peer-reviewed scientific journal “The New England Journal of Medicine” (NEJM) contributed to this knowledge. The study looked at the effectiveness of a booster dose of Pfizer-BioNTech (BNT162b2) vaccine in preventing death from SARS-CoV-2 infection. The analyzes were carried out on the basis of data from over 843,2 thousand. patients in Israel, the first country to start administering the third dose of the COVID-19 vaccine.

90 percent lower risk of death after the third immunization
The study lasted from August 6 to September 29, 2021 and covered 843 data. 208 patients of Clalit Health Services (the largest of Israel’s four health care organizations) aged 50 and over (mean age of participants was 68,5 years). These people had been vaccinated with Pfizer-BioNTech at least five months earlier, with 90 percent of them being vaccinated. of them (758 118) received a booster dose. What conclusions have the researchers’ analyzes brought?

As we read in the pages of “NEJM”, those who got a booster injection at least five months after the second dose of BNT162b2 had 90 percent a lower risk of death from COVID-19 than those who did not receive a booster dose. As for the detailed results, 65 deaths (0,16 per 100) were recorded in the group of people with the booster, and 137 deaths (2,98 per 100) in the group without a booster dose.
The authors point out the limitation accompanying the analyzes – the relatively short study period (54 days). «However, at that time, the incidence of COVID-19 in Israel was one of the highest in the world. Moreover, the social distancing restrictions imposed on Israeli society were limited. Consequently, exposure to SARS-CoV-2 was significant, so the number of deaths from COVID-19 was sufficient to demonstrate a significant association between booster dosing and lower mortality from COVID-19, reads The New England Journal of Medicine ».
