Essentially, what this study demonstrates is that there's a distinct possibility that those who received it, especially the Pfizer vaccine, could have suffered from adverse side effects that contributed to all-cause and heart-related mortality rates.
Maybe the "experts" should have waited a bit longer before running with the "safe and effective" messaging line after all. Vaccine efficacy fell to zero, particularly against infection, with the advent of new and more transmissible variants. When rigorous criteria is applied, safety and efficacy against severe outcomes does not always align with the prevailing pandemic wisdom.
As is and was so often the case, with masks, schools, lockdowns and many other absurd COVID policies, those who set "the science" were wrong. With catastrophic results.
