That is, itself, a feat of unity. A year ago most of us didn’t know how to get tested for COVID-19. That millions of Americans are now vaccinated against it is a direct, remarkable result of unity — among scientists, funding donors (Dolly Parton!), political leaders, health care workers, transportation workers, the National Guard, community advocates and good-hearted souls (Chicago Vaccine Hunters!) volunteering their time to demystify the process, track down appointments and drive folks to get their shots.
