In the spring we wondered if a vaccine for COVID-19 would even be possible. Then, early projections said the development process might take multiple years, putting the first public distribution around this time next year or even later, which is horrible to contemplate even as a now-avoided hypothetical.
Instead of that timeline, we got this one — a pretty amazing one, frankly, in which highly effective vaccines were developed and safety tested in record time. Distribution began in the United States this week. It will take a few months, but the end is in sight. By summer, it appears, everyone in America who wants a COVID-19 vaccination will be able to get one.
