Pfizer vaccine reduces COVID-19 transmission by nearly 90%
According to the data collected by the Israeli Health Ministry, as well as by Pfizer and BioNTech, the vaccine is almost 90% effective in reducing coronavirus transmission. The joint study of the pharma companies and the Ministry of Health of Israel proved that the vaccine created by Pfizer and BioNTech is highly effective as it prevents further spread of the virus in 89.4% of cases. The study was held in Israel where almost a third of the population has been vaccinated. Researchers state that among those who received two doses of the vaccine, 1,842 cases of COVID-19 infection were reported. At the same time, 76,797 infection cases were found in the unvaccinated group. The Lancet medical journal has recently published a study of the Sheba Medical Center in Israel. According to it, the efficacy rate of the Pfizer and BioNTech vaccine is 85%. This result is achieved right after the first vaccine dose is administered. At the same time, the vaccine reduces the risk of contracting infection by 75%. In November 2020, Pfizer claimed that its vaccine was 95% effective and showed great results in all groups of volunteers regardless of age, gender, or ethnicity.
