Real world evidence from Israeli Ministry of Health analysis confirms high effectiveness of the Pfizer-BioNTech COVID 19 vaccine
The Israel Ministry of Health (MoH), Pfizer Inc. and BioNTech SE announced real-world evidence demonstrating dramatically lower incidence rates of COVID-19 disease in individuals fully vaccinated with the Pfizer-BioNTech COVID-19 Vaccine (BNT162b2), underscoring the observed substantial public health impact of Israel’s nationwide immunization program.
These new data build upon and confirm previously released data from the MoH demonstrating the vaccine’s effectiveness in preventing symptomatic SARS-CoV-2 infections, COVID-19 cases, hospitalizations, severe and critical hospitalizations, and deaths. The latest analysis from the MoH proves that two weeks after the second vaccine dose protection is even stronger – vaccine effectiveness was at least 97% in preventing symptomatic disease, severe/critical disease and death. This comprehensive real-world evidence can be of importance to countries around the world as they advance their own vaccination campaigns one year after the World Health Organization (WHO) declared COVID-19 a pandemic.
Findings from the analysis were derived from de-identified aggregate Israel MoH surveillance data collected between January 17 and March 6, 2021, when the Pfizer-BioNTech COVID-19 Vaccine was the only vaccine available in the country and when the more transmissible B.1.1.7 variant of SARS-CoV-2 (formerly referred to as the U.K. variant) was the dominant strain. Vaccine effectiveness was at least 97% against symptomatic COVID-19 cases, hospitalizations, severe and critical hospitalizations, and deaths. Furthermore, the analysis found a vaccine effectiveness of 94% against asymptomatic SARS-CoV-2 infections. For all outcomes, vaccine effectiveness was measured from two weeks after the second dose.
In January 2021, Pfizer and the Israel MoH entered into a collaboration agreement to monitor the real-world impact of the Pfizer-BioNTech COVID-19 Vaccine. Detailed findings from this collaboration also will be submitted to a peer-reviewed journal..
