New Covid boosters aren't better than old shots at neutralizing omicron BA.5, early studies find

 

KEY POINTS

• Scientists at Columbia and Harvard, in two independent studies, found that the new Covid boosters don’t trigger a better response against omicron BA.5 than the old shots.
• The studies are small and preliminary, but they suggest boosters might not be much better at preventing infection and mild illness.
• But the new boosters appear to produce at least as good an immune response as the old shots, which means they’ll still increase protection this fall and winter.
