Is Pfizer vaccine less effective against delta variant?

 Some health experts expressed skepticism about the Israel study

A study conducted in Israel found that the Pfizer COVID-19 vaccine is somewhat less effective against the more infectious delta variant, though it was still found to be effective at preventing severe illness.The Pfizer vaccine protected 64 percent of immunized people during an outbreak of the delta variant, a sharp drop when compared to the 94 percent of people it had previously been shown to protect. However, the shot was still 94 percent effective at preventing severe illness, a slight decrease from the 97 percent that were kept from experiencing severe illness previously.

The data for the study was collected from June 6 through early July, according to officials from Israel’s Health Ministry. The data and the methodology of the study was not released, according to the Journal. Some health experts expressed skepticism about the Israel study, saying mRNA vaccines like Pfizer have been shown to offer strong protection against COVID-19 infection.
