That doesn’t back up what you are saying.
It seems to me that vaccines are broadly effective in that they will largely prevent serious symptoms, and are likely to significantly inhibit transmission, but that’s a different thing altogether to what you claimed - that they are 100% effective at stopping contraction and transmission. My reading is that we still don’t know for sure exactly how effective vaccines are stopping contraction, never mind transmission, and we probably won’t know that for a while.
Vaccines are great but they aren’t foolproof and rely on critical mass being achieved at a population level to achieve maximum effect.
