I don't know where you get your information but I saw absolutely zero change in the info on any of the major vaccines since the very same day they've been announced. From day 1 the message was always that these vaccines trained the immune system to lower the severity of Covid symptoms, but otherwise we could still catch it and spread it.
Then only significant change that popped up since last year was due to the inception of the so called Delta variant, which is an entirely new development and had just enough mutations to lower vaccine effectiveness. However, the mRNA vaccines were, from the very start, described as custom tailored to the existing variants, and we're expected to show a drop in effectiveness if the wrong kind of variant occurred.
Personally, when I received my jabs, in both occasions I received a small flier making it quite clear that the current Covid vaccines only trained the immune system to have a fighting chance against Covid, but we were still vulnerable to catch and spread Covid and thus we should continue to practice basic health and safety precautions.
So I really wonder where you got your info, because none of what you said correlates with reality.
