Pfizer and BioNTech’s Covid-19 vaccine proved 89.4% effective in stemming the spread, says an Israeli study. A person familiar with the work confirmed the effectiveness that was posted on Twitter. Early evidence showed that the vaccine prevents the illness and cuts the spread as well. However, experts have been cautioning that the effectiveness of the vaccine in spreading the virus is questionable.
Bloomberg reported that Pfizer, BioNTech, and the Israeli health ministry study provides a strong indication. The report stated that the vaccine did indeed curb the spread of the virus. An early draft form also says that the vaccine may also prevent the transmission by asymptomatic carriers.
Although this has not yet been paper reviewed, early draft posting suggests the same. The clinical trials that tested the safety and efficacy of the vaccine primarily focused on stopping asymptomatic infections. Hence, the transmission of asymptomatic carriers cannot be confirmed as of yet.
Israeli authorities also said that the shot is 99% effective in preventing Covid-19 induced deaths. So far, nearly half of the Nation’s 9.05 million people have already received the shot. Israel has administered more vaccines per capita than any other country. The rollout of the Pfizer vaccine in a national immunization program began on 20th December 2020.
Around 27% of people aged 15 or older were fully vaccinated with both doses through 6th February. These people were considered fully vaccinated and included in the study if the data collected was after more than seven days of the second dose. According to research, the shot was effective 47% in the first two weeks after administration.
