We're starting to see more and better reporting on why some countries are able to vaccinate so quickly, and why others are lagging behind. I'll compile them in this thread in the future.

. @BelleTimsit analyzes what's helping Israel, Bahrain, and the UAE: universal healthcare, early approval, digitalization of health care, population attitude ("a mood evocative of wartime"), example set by political & religious leaders including minorities. https://qz.com/1953007/the-countries-with-the-most-effective-covid-19-vaccine-rollouts/

. @naomiohreally focuses on Denmark (important as people in the EU may see it as more comparable): digital & centralized system, use of the "6th dose" technique, but more importantly the decision to go all-in on first doses (instead of reserving 2nd doses). https://www.irishtimes.com/news/world/europe/how-denmark-is-administering-vaccines-at-three-times-the-rate-of-ireland-1.4457739

There have been a few threads on Israel's success, but this one by @VKJudit was the most detailed I've seen so far. https://twitter.com/VKJudit/status/1348599933650296832

Great thread & article by @eladgil on Israel:
• Focus on simplicity (simple tier system by HCW status & age)
• Vaccinate in as many places as possible
• Don't waste doses
• Publicize your success (the Israeli gov't has been sharing many of our charts!)
