Also, variants changed matters rather significantly. The vaccine is designed to deal with a version of COVID that has effectively been competed out of existence. Now, the vaccine still provides rather durable T-cell protection, but it no longer provides the level of antibody protection that it once did. The messaging has changed because the reality has changed, and at current the reality is that the vaccine still prevents some (instead of most) infections, but still reduces the duration of infection and drastically reduces the severity of infection.
And yeah, it's entirely possible that a new variant could arrive that would change that, too. That wouldn't be science changing its story, that would be science reacting to changing circumstances. Which is how science works.
