WASHINGTON — To hear top officials in the Biden administration tell it, the effort to vaccinate Americans is a contest against the coronavirus, a determined opponent that could flare into a new surge (as it recently did in Michigan) or evolve into new variants before enough people have been inoculated to stop community spread.
“We’re still in a life-and-death race against this virus,” President Biden said earlier this month. He has frequently announced more aggressive vaccination timelines, promising that there would be enough vaccines for every American by the end of May. His administration kept to that goal even as the Johnson & Johnson vaccine was taken out of circulation
