This borders on intellectual dishonesty on your part. They’re saying the vaccines, with their effectiveness around the original quoted numbers were ineffective against a new variant.

There are hundreds of other articles detailing ineffectiveness of the vaccines and lowering efficacy. It is well known that the institutions also changed the narrative to say that vaccines were never about "transmission"

I've seen a 2 minute long video showing the declining percentages mainstream media claimed on the vaccine over the course of 3 months. Perhaps this one particular article was dishonest however.

Your original statement was that they lied about the effectiveness. The article you presented to back that up was about how the effectiveness was different for a different strain. So either you didn't read the article, didn't understand it, or were being dishonest.
