There’s no question the vaccines are imperfect and their ability to prevent disease wanes pretty quickly, especially against the Covid variants. There’s also no question they’ve proven very effective in preventing serious disease and death.
Regardless, I think our public health community has been acting in good faith and I don’t think there’s been a big conspiracy to deceive the public or hide negative information.
I regret your naivete. I’m afraid you and many others will live to regret it also.
