A century ago, as the United States recovered from a worldwide pandemic and a major war, a presidential candidate wisely and successfully called for “a return to normalcy.” Warren G. Harding, in a campaign speech in 1920, could well have been speaking to people today when he said the “need was not heroics but healing, not nostrums but normalcy.”

With airplanes and hotels filling up, fans returning to ballgames, and even highly regulated California planning to open up in June, daily life is slowly returning to normal. As Dr. Anthony Fauci has said, “We all want normalcy in America, and the highway to that normalcy is vaccination.” More than half of adults in the U.S. have received at least one shot of the COVID-19 vaccine, and all adults are now eligible.
