Fair point. Near 0%.
The glasses are really quite an apt analogy to the transmission rate with a COVID vaccine. It's not that you can't transmit, but your risk of doing so is several times lower. Nor is it the case that I couldn't drive my car without my glasses, but it's a lot safer if I wear them, so it's required by law.
Personally I like that requirement. Yes, it's theoretically a restriction on my rights, but I like the idea that other people on the road are also subject to that restriction; it makes me safer. Same goes for the vaccine.
