Dishonesty can never satisfy intellectual curiosity. It’s not an insinuation, it’s a scientific possibility that warrants further investigation, especially when boosters are being rushed to market with similarly abbreviated clinical trials. There are some reasons for suspicion. One is the rapid fading of the vaccine’s effectiveness. Why is it so much faster than expected? What’s the mechanism? Another is that every other coronavirus vaccine tested has resulted in decreased immune function due to Antibody dependent engancement. Do we know the current vaccines cause ADE? Not so far as I’m aware. Is it something that should be researched? I’d say so.
Not being aware of any research about ADE doesn’t mean it hasn’t happened… There has been a ton of it and it tends to be something that shows up pretty evidently in clinical trials.
