Pfizer Inc.’s Covid-19 vaccine provided a strong shield against hospitalization and more severe disease in cases caused by the contagious delta variant in Israel in recent weeks, even though it was just 39% effective in preventing infections, according to the country’s health ministry.
The vaccine, developed with BioNTech SE, provided 88% protection against hospitalization and 91% against severe illness for an unspecified number of people studied between June 20 and July 17, according to a report Thursday from the health ministry.
The data could be skewed because of different ways of testing vaccinated groups of people versus those who hadn’t been inoculated, according to the report.
