“If he were here now, he would implore us to remember what made it possible to defeat polio: a national effort to develop and test the vaccine and a world-wide effort to make vaccination available to everyone without profit. Millions donated money and volunteered their children for the largest field trial in public health history. International organizations and governments worked to ensure the entire world could get vaccinated. My father would insist on also making COVID-19 screening, treatment and vaccination available to all of us, regardless of where we live or our social or economic standing. He would argue that doing so is not only morally right, but profoundly in our national and global interest. When it comes to infectious disease, health — unlike wealth — can’t be hoarded by the few. As long as a virus is circulating in an unimmunized population, it’s a threat to all, and it’s in all our interests to contain, prevent and eradicate it.”
