In a worrying trend, a recent study by the Israeli health ministry on Friday, revealed that Pfizer’s Covid-19 vaccine is less effective at preventing infection and symptomatic cases from the Delta variant of the Coronavirus (COVID-19). The study stated that the Pfizer-BioNTech vaccine was 39% effective at preventing infections and 41% effective at preventing symptomatic infections from the Delta variant, which is lower than the early estimates of 64%. Pfizer is currently seeking US CDC's approval for a booster dose for those vaccinated.
