This is amazing. December 2020. As late as this April, people—including Dr. Fauci—thought 18 months was probably too optimistic a timeline for vaccines. And we’d have been thrilled with ones much less efficacious than these. And multiple ones are in the pipeline. It is a triumph. https://t.co/g8y10YwFkN

Yeah, that is amazing. Remember, not that long ago many experts said that a vaccine for a coronavirus was impossible. I saw that “wisdom” as recently as four months ago. Once, it was a fairly common take and only abated (and tweets got deleted) when it was clear not just one but many vaccines would be available.

That’s real tech there. Facebook is not.
