How about this post?

You’re taking a study that isn’t about vaccine effectiveness, and you’re using it to say that the vaccines aren’t very effective. You say that you’re not discouraging people from getting the vaccines, and I’m sure that’s not your intent, but incorrectly stating that the vaccines are less effective than they actually are will nonetheless have that effect.

The vaccines are still extremely effective at what they were designed to do, even in the face of new variants. It turns out, to the surprise of nobody but the pessimists, that they’re also somewhat effective at preventing infection. That’s a nice added bonus, in addition to their primary effect.
