Challenge accepted. Though I think we've had this same conversation before. This forum is like groundhogs day.

Here's a great example:
covid vaccine

In this he suggests the vaccine "isn't as effective as we thought" based on one person contracting the virus a week after the first dose. No one claims that a person is protected then, and he gives lip service to that in the last paragraph, but only after a click-bait headline and a clearly false statement about vaccine efficacy.

I recommend you look at each of these articles and ask "what is the purpose of this story?" Then replace "purpose" in that question with "agenda.". For this it's clearly to cast unfounded doubt on the effectiveness of the vaccine.
