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.
