An earlier real world study had showed effectiveness at preventing symptomatic disease at 94% and asymptomatic illness at 92%.<\/strong><\/em><\/h4>\n

Pfizer Inc and BioNTech SE said that real-world data from Israel suggests that their COVID-19 vaccine is 94% effective in preventing asymptomatic infections, meaning the vaccine could significantly reduce transmission.<\/em><\/p>\n

The companies also said the latest analysis of the Israeli data shows the vaccine was 97% effective in preventing symptomatic disease, severe disease and death. That is basically in line with the 95% efficacy Pfizer and BioNTech reported from the vaccine\u2019s late-stage clinical trial in December.<\/cite><\/em><\/p>\n

The analysis also shows real-world evidence of the vaccine\u2019s effectiveness against a highly infectious variant of COVID-19 first discovered in Britain, known as B.1.1.7. More than 80% of the tested specimens when the analysis was conucted were variant B.1.1.7.<\/cite><\/em><\/p>\n

There was only a limited number of infections in Israel caused by the so-called South African variant – known as B.1.351 – so they were not able to evaluate vaccine effectiveness against this variant.<\/cite><\/em><\/p>\n

Israel is leading the world in its vaccination roll out, due in part to an agreement to share data with Pfizer and BioNTech. As of Wednesday, around 55% of its 9 million population had been given at least one dose of the Pfizer\/BioNTech COVID-19 vaccine, according to Health Ministry data, and 43% have received both doses.<\/cite><\/em><\/p>\n

According to the analysis, unvaccinated individuals were 44 times more likely to develop symptomatic COVID-19 and 29 times more likely to die from COVID-19 than those who had received the vaccine.<\/cite><\/em><\/p>\n

The data, collected between Jan. 17 and March 6, has not yet been peer reviewed.<\/cite><\/em><\/p>\n

Israel\u2019s Health Ministry previously found the Pfizer vaccine developed with Germany\u2019s BioNTech reduces infection, including in asymptomatic cases, by 89.4% and in syptomatic cases by 93.7%.
