Updated Covid vaccines, expected soon after Labor Day, were designed to thwart Omicron variants. But money to distribute them has dried up.
Long past the point when pollsters said there were no more Americans willing to be vaccinated against the coronavirus, Coral Garner kept finding them.
An organizer of mobile clinics for the Minnesota Department of Health, she arranged to provide vaccines and booster shots to people who had resisted them, setting up in a retrofitted city bus outside a Nigerian church, a Hmong senior center, a Somali mall and dozens of other sites.
But even as the United States now prepares for a critical campaign to deliver Omicron-specific booster shots, Ms. Garner’s job no longer exists. In June, her contract position was canceled because the state said funding had dried up.
