Pfizer vaccine less effective against Delta variant, according to study in Israel
A study in Israel has explained that BioNTech/Pfizer COVID-19 vaccine appears to be less effective at preventing COVID-19 cases caused by the Delta variant.
YNET news – an Israeli news organisation – has stated that according to the Israeli ministry of health the vaccine is less effective against coronavirus infection rates.
“The effectiveness of the vaccine against infection has dropped to 64% in the past month, against the background of the spread of the Delta strain and the cancellation of restrictions”.
However, the data suggests that the vaccine is still extremely effective in hospitalization rates. Between the 2nd of May and the 5th of June, the vaccine was 98 percent effective at preventing hospitalizations.
Moreover, according to POLITICO, this data is also supported by UK data, as they stated: “The vaccines are less effective at preventing infections with the Delta variant, but that they remain effective at preventing severe disease”.
Public Health England has further explained that one dose of the vaccines provides between 55 to 70 percent efficacy, and two provide 65 to 90 percent.
