Probably not even worth attempting given our border has so many illegal crossings.
Covid-zero is impossible in any open society. China is still pursuing a covid-zero policy, but even with locking down entire cities and imposing travel bans they're far from zero.
I think this dichotomy (prevents vs doesn't prevent) is false. Vaccination reduces the likelihood of getting infected and it reduces the likelihood of severe illness. Perhaps not to the same degree, but my point here is that it's not black & white as the quoted wording implies.
It may increase it by selecting the un-protected strains.
> it doesn't prevent infection or transmission
Source? We’ve (largely) vaccinated our way out of other diseases. I haven’t heard of any outbreaks of mild measles or mild rubella and I suspect it’s because vaccination gets the R lower.

If we end up with measles2 and rubella2, I wouldn’t be surprised if my measles1 and rubella1 vaccines weren’t effective.
Windsor Ontario has something like 1000+ health care workers commuting to the Detroit area that have been exempt from most entry test/vaccination/quarantine requirements. Same for truckers and flight crews and ~30 other groups.
I think this is only changing next week with an actual vaccination requirement.
If you want to go for covid-zero, go for it, but if you half-ass it, you get all the disadvantages without any of the advantages.
