It's pretty clear the the vaccine does not stop transmission of the virus.

"But Israel paid a price for the early rollout. Health officials, and then Pfizer, said their data showed a dip in the vaccine's protection around six months after receiving the second shot."
That doesn't exactly fit your narrative, imo.
A dip in effectiveness after 6 months seems to follow that line of reasoning just fine.
No one should be reasonably expected to get a booster every 6 months.
Side note: I also can't stand when the "total vaccinated %" includes children. We all know they can't be vaccinated yet and any total % vaccinated that includes them is disingenuous. I realize it was my source, but I digress.
