Israel believes that the Pfizer vax is "just 64% effective at preventing symptomatic infections"...Well 39% > 0 (unless you're a proponent of masking & lockdowns.)
"Pfizer and BioNTech’s Covid-19 vaccine is just 39% effective in Israel where the delta variant is the dominant strain, but still provides strong protection against severe illness and hospitalization, according to a new report from the country’s Health Ministry.
However, the two-dose vaccine still works very well in preventing people from getting seriously sick, demonstrating 88% effectiveness against hospitalization and 91% effectiveness against severe illness, according to the Israeli data published Thursday."
