When the virus first emerged, let's call it type A, the vaccine did help reduce transmission, reduce not stop, it did that by lowering the viral load of vaccinated people as their immune system kicked in quickly and the virus did not get as big a hold on them(statistically that is, there are always exceptions), as further variants emerged this effect was lessened, not stopped, by the fact the virus had become more transmissible, I'm still totally comfortable with the science, scientists did an amazing job under extreme pressure to deliver the vaccines to the world, just as an aside, more Australians have died from the virus in the last 6 months than at any other time since the pandemic started, mostly old people, they don't count apparently.
