Pfizer CEO Albert Bourla said people who’ve gotten both doses of the Pfizer-BioNTech jab would likely need a third shot within 12 months and might need an annual shot thereafter. “There are vaccines … like polio that one dose is enough, there are vaccines like pneumococcal vaccine that one dose is enough for adults, and there are vaccines like flu that you need every year,” Bourla said. “The COVID virus looks more like the influenza virus than the polio virus.”
