I might be wrong on this, but wouldn't that still be fine in order to achieve herd immunity?

I distinctly remember reading something that said 60% was the minimum threshold required to ensure that the virus spread as a greatly reduced rate.

It's all estimates, of course, but there's some good reading about what factors effect the herd immunity threshold here: https://en.wikipedia.org/wiki/Herd_immunity#Mechanics They estimate 50-83% vaccination threshold to achieve herd immunity for COVID-19. I believe the citation is this study, but I admit my ability to read scientific papers is lacking: https://pubmed.ncbi.nlm.nih.gov/32433946/

Right now they are saying that 95% had a substantial immune response. But we do not know whether it is substantial enough and lasting enough. Imagine that it is both for less than 70% of vaccinated. 5/6*0.7<0.6 (and yes, 0.7 is to prove a point).
