The conspiracy is in the utterly baseless claims you made that the truth was being hidden and disinformation was being spread on purpose by the media.
The reason vaccines have limited efficacy with Covid-19 unlike other diseases like polio and smallpox is that Covid is highly mutable, in the first place. And polio and smallpox weren't. Questioning the efficacy of vaccines against Covid on this basis is nonsense, and demonstrates a lack of understanding of the underlying pathogen.
You're deeply confused as to why smallpox and polio vaccines were so effective, and COVID and influenza vaccines are currently not as effective. Also on the time scales involved.And all of this is the opposite of vaccines that offer sterilizing immunity against contact-based viruses. Viruses that should not ever become endemic. The official institutions are not making the distinction here. They're still busy gaslighting people about what they promised.
Smallpox's earliest vaccination-type efforts started back at the end of the 18th Century. It wasn't until 160 years later that the WHO made a concerted global effort to eradicate the virus. Even once started, it had limited effect for years, before the intensified Eradication Program of 1967 kicked off. And even then, it took another decade of concerted efforts globally before the goal was finally achieved in 1977, nearly 200 years after Jenner first figured out that cowpox could be used to generate immunities in human patients.
Polio, similarly, saw a global eradication effort kick off in 1988, and that effort is still ongoing, and by no means complete.
Meanwhile, COVID's only been a factor for humans for a couple years, as near as we can tell. Expecting the same outcomes as smallpox and polio after both diseases had multi-decadal global eradication campaigns is absolute lunacy.
All you're doing is demonstrating a weird hostility to vaccination programs. It's rather disturbing and you're right on the conspiracy fringe on all of this.
