Pfizer Scientist Expects Seniors, People With Underlying Conditions to Be First to Get COVID Vaccine Booster Shots

Pfizer's chief scientific officer Mikael Dolsten told investors this week that high-risk groups like seniors and people with underlying medical conditions will likely be prioritized to receive booster shots of the Pfizer-BioNTech COVID-19 vaccine, reports CNBC . He said it makes sense to put the most vulnerable groups at the front of the line. The two-dose vaccine has demonstrated about 95 percent effectiveness against the virus two weeks after the second dose, although those who helped develop the shot now say they are starting to notice that strong protection fades over time. Executives at Pfizer and BioNTech previously said people will likely need booster shots of the vaccine within 12 months of getting fully vaccinated, as well additional shots annually.
