I think the parent is asking (if 1 shot of this vaccine confers 80% immunity) would it not be better (for the purposes of curbing transmission) to give everyone a single injection now for 80% immunity among a broader population rather than giving half the number of people two doses for 90% immunity. The implicit constraint is that it will take a relatively long time to scale up production and distribution to the extent that we can get two doses to everyone.

I understand what OP meant, but the data we currently have shows that one shot of this vaccine is not likely to convey a decent amount of protection.

I am sure I misunderstood something, but what does that 80% mean, and how does it differ from "the data we currently have shows that one shot of this vaccine is not likely to convey a decent amount of protection."?

The 80% number was made up in this conversation. The vaccine has not been tested using only one shot and we don't know how effective it might be.

Oops my bad
