Recent data from Israel’s health ministry suggests Pfizer’s Covid-19 vaccine is far less effective at preventing infection and symptomatic illness with the Delta variant than with previous strains of coronavirus, a finding that conflicts with other research indicating high levels of protection against the contagious variant as countries around the world struggle to contain new waves of infection.
A full course of the Pfizer-BioNTech vaccine was just 39% effective at preventing infections and 41% effective at preventing symptomatic infections caused by the Delta Covid-19 variant, according to Israel’s health ministry, down from early estimates of 64% two weeks ago.
The figures, based on data from an unspecified number of people between June 20 and July 17, are significantly lower than previous estimates of the vaccine’s efficacy against other variants, which initial clinical trials found to be 95%.

.... French Guiana, We describe a COVID-19 Gamma variant cluster with a high attack rate even in fully vaccinated persons.
