Not strictly clinical data, but in some ways better since it is real world data https://www.yahoo.com/news/israels-rapid-rollout-provides-the-first-realworld-proof-that-covid-vaccination-works-as-well-as-promised-152103525.html My biggest takeaways in a sample roughly 4 times bigger than the original clinical trials Pfizer is still 92% effective at preventing clinically noticeable symptoms, but 100% against hospitalization and death in a group that heavily skews towards the highest risk. And it still seems to be working as well against the UK variant. I would encourage everyone to talk this up, frustration with the speed of availability is the problem of the moment but the problem of the future is going to be pushing the vaccination level worldwide high enough to put Covid close to eradication. That is almost exclusively a problem of hesitancy, and it is as simple as every infection is a lottery ticket that might hit on the winning combination that can evade the vaccine and start the madness all over again. I'm asking everyone to help on this because frankly the literature out there on these types of science communication issues is utterly depressing and positive messages from friends and family is way more likely to convinced people than any advertising, public service announcements, an army of Neil deGrasse Tysons, Faucci's, or anyone else you can think of.
