I don’t think there was ever a claim that having the vaccine would stop transmission or contraction robin202, but rather that it would likely reduce, for the majority, the severity of Covid should you be unfortunate to get it. Scaremongering “statistics” help no-one, and can actually be very damaging.
As with any vaccine, it isn’t 100% effective, and indeed, and unfortunately, there have been cases of very adverse reactions to vaccines for some people - but this has always been so. There will always be an element of risk.
