A sneak-peak to the Israelian study on the administration of Pfizer vaccine

Lately, a professional team of Israeli researchers confirmed that Covid-19 infections had a great reduction by 75 percent after the first dose administration of the first dose of Pfizer vaccine.

According to the published Pfizer vaccine data in the peer-reviewed Lancet medical journal, the study was centered on around 9,000 Sheba healthcare workers, and about 7,000 received their first dose in January 2021.

Data confirmation from Sheba Medical Center said that between 15-28 days after Pfizer vaccination, there was a 75 percent decrease in all infections and an 85 percent reduction in symptomatic infections.

According to Gili Regev-Yochai, director of the hospital’s Infectious Disease Epidemiology Unit, ‘only 170 people became infected during the two-week period. Of those who contracted the virus, 99 showed symptoms. Eighty-nine of the sick were unvaccinated. Further discuss with her is that the hospital is now completing research on the impact of the second dose, which she said researchers still believe is essential.

Gili Regev-Yochai noted that the research supports the UK government’s decision to spread out the time between the first and second shots of the vaccine in order to inoculate more people. A shortened data finding is that the hospital workers under the age of 65 were healthier than the rest of the population, which connotes the possibility that fewer people got sick or showed symptoms for that reason.
