Pfizer data from Israel finds vaccine prevents 94% of asymptomatic infections

Details: The analysis came from real-world data collected between Jan. 17 and March 6 in Israel. Vaccine effectiveness was measured two weeks after the patient received their second dose.

• The shot was found to be 97% effective at preventing symptomatic cases, hospitalizations and deaths, supporting Pfizer's clinical trial findings that said it was 95% effective.
• Unvaccinated people were 44 times more likely to develop symptomatic coronavirus and 29 times more likely to die from the virus.
• The analysis was also conducted at a time when more than 80% of the tested specimens were the B.1.1.7 coronavirus variant first discovered in the U.K. — providing real-world evidence of the Pfizer vaccine's effectiveness against one of the more contagious strains.

Worth noting: This data has not yet been peer-reviewed.
