So now it is simple math. Let's use 1% breakthrough-----so 1 in 100 vaccinated people can get the virus, then they have to be unmasked and close enough to another person for 15 min (less for delta variant). Then, if that person is vaccinated, they have to be the 1 in a hundred that could breakthrough themselves, and so on. So the odds of a vaccinated individual passing COVID to another vaccinated person is well under 1 in 10,000 (0.01%). Increase the breakthrough percentage to 5% and you still get less than 0.25% chance.
That is why this is now essentially a pandemic of the unvaccinated.

Care to explain why out of 7700 Delta infections in Israel from May to July
40% (3000) were fully vaccinated individuals
1% (72) were covid survivors with natural immunity
59% (4699) were unvaccinated individuals
Hardly a pandemic solely of the unvaccinated. Israel mostly used Pfizer vaccine.
Mayo Clinic study shows Pfizer vaccine only 42% effective against Delta. As of today 197 million doses of Pfizer vaccine have been administered in the USA. So about 100 million people citizens have only 42% protection against Delta.
CDC has stopped reporting breakthrough cases for some reason.
