Science spoke with clinicians, vaccine researchers, and biostatisticians about how they view the value of these latest shots. Several cautioned against falling into extremist camps—boosters are worthless or everyone must get boosters. “I just want people to have tempered expectations,” says Natalie Dean, a biostatistician at Emory University who specializes in evaluating vaccines. “There is room for reasonable debate about how much added value there is for a young, healthy person.” Two years ago, with the pandemic raging and vaccines dramatically cutting serious illness and death, there was little doubt about their value for everyone.
