The question of whether we can reach herd immunity is not one virologists can answer. It's a health policy and health behavior question.https://twitter.com/TheFerrariLab/status/1389321866742018052 …

I look forward to reading it. One question for me: polio was eliminated in the U.S. in the late 1970s, but world efforts started in late 1980s. So there was herd immunity. I suspect it’s a different disease, different pattern issue, but would like to read an informed analysis.

I think the big difference is that while it's possible a single course of COVID-19 vaccines will prevent disease indefinitely, it's not certain or even necessarily likely, especially with variants continuing to emerge globally

Exactly. And even then...the vaccinated first can be reinfected or should roll mass boosters again.

Does it follow, then, that we should give vaccine away to other countries? We worked hard, made strategic investments, and soon will have made these available to all in he US. We can’t squander our blessings by leaving doses unused when they could save lives elsewhere.

If we get to high vaxx rates it will protect us quite a lot even if the rest of the world isn't protected. We are likely going to need boosters, but that doesn't negate the benefits of a year of HI if we get to the threshold.

The much more serious question is nerd immunity. Politician's refusal to listen to expertise.
