Vaccines on a shelf won’t usher the end of a pandemic, and getting them into arms takes work. Oklahoma has administered nearly 3 million doses of COVID-19 vaccine. Like all other states, it has done so free of charge to residents. That is possible largely because thousands of volunteers pitched into the effort. Diana Schaeffer retired as a public health nurse in October, as case counts began surging. She knew first-hand how exhausting the pandemic response would be for health department workers across the state; she was chief of nursing at the State Department of Health for 14 years.
