Sounds like around 10% of the US population that ought to be vaccinated is not going to be. That's around 30-35m people.
For that block, herd immunity is the only solution. It's going to mean higher death rates. But conspiracy theorists, anti-vaxxers, freeloaders, Trump hatriots and freedumb-lovers shouldn't be able to hold the country to ransom.
Expect more stories of proudly unvaccinated and ultimately regretful people dying. Darwin is waiting for them.
