Most recent poll shows 78% of Americans are willing to get the covid vaccine with 2% undecided. 20% still firmly say it’s never going to happen for them.

Some quick math - 78% of the population is 257M people. Right now without any additional vaccine candidates coming through the US has enough doses secured for 185M people by June (200 million by July) between Pfizer and Moderna. If one of the others comes through and delivers enough doses for another 100 to 150 million people (JnJ 100M doses or AstraZeneca Oxford 300M doses) that would put us well over the top towards the goal of getting enough for anyone who wants a vaccine by the end of June or sooner. There’s also a very good chance that 78 to 80% vaccinated would be more than enough to reach herd immunity.
