Speaking of Vermont—

I’ve been compiling Vermont biweekly reports (found on their covid website) and taking the differences in data to estimate breakthrough case, etc. Keeping in mind, because of testing protocols, etc., any breakthrough data is likely the lower limit, it’s highly evident this is not solely an unvaccinated driven occurrence.

Since the end of August (starting with the August 27 report) every two week interval of Covid reporting has demonstrated:

Breakthrough cases: biweekly range 31-45%, with 35% all of covid cases being breakthrough from 8/27 - 11/17

Breakthrough hospitalizations: biweekly range 30-48%, with 36% all of covid hospitalizations being breakthrough from 8/27 - 11/17

Breakthrough deathd: biweekly range 45-83% (!), with 59% all of covid deaths being breakthrough from 8/27 - 11/17

Additionally, death rates per case have been routinely higher in the breakthrough crowd. August 27 through November 17 report, breakthrough deaths to case ratio is 1.2%, while non-breakthrough is 0.4%.

Clearly, the vaccine is not bulletproof. I also think these numbers are lowballed, as the interest in tracking this effectively in the US seems to be lacking.
