Could the Delta variant change that picture? Two doses of Pfizer’s vaccine are still 88% effective at preventing symptomatic Delta infections, and 96% effective at preventing hospitalization. It is a sign that even highly vaccinated countries host plenty of vulnerable people. Of the 3 billion vaccine doses administered worldwide, about 70% have gone to just six countries; Delta has already been detected in at least 85. The WHO’s decision to name variants after the Greek alphabet means that at some point, we’ll probably be dealing with an Omega variant.
