If you only think in binary, that might be correct.
Is it possible for a vaccinated person to spread the virus? The answer seems to be yes. Will a vaccinated population spread the virus as quickly and as easily as an unvaccinated population? Absolutely not. While it is possible for a vaccinated person to become infected and possibly spread, it is far less likely: I have read their chance of becoming infected is less and the length of time they carry the virus is less. Put the virus in a crowd of vaccinated people and it has a hard time finding a way to reproduce and survive.
Does that drive it to zero? Maybe not, but it drives the amount of virus in the community down which reduces the likelihood that the few unprotected individuals encounter it.
Vaccines don't need to be 100% effective and they don't need to be taken by 100% of the population in order to make the world safe. Determining the numbers to make this work is beyond my simple math but it is pretty clear that 70% uptake is not sufficient.
