The flaw in your logic is to attribute all incidences of clotting & heart attacks to vaccines. During the time people were Unvaccinated (no vaccine was available) studies done using US medical records has clearly shown that the incidence of blood clots in COVID-19 illness ranged anywhere from 5 to 40 percent, varying with individual risk factors and severity of illness.
Also there are many cases during the pre Covid era where young people had passed away due to embolisms & heart attacks. Scientific evidence has to be backed by real data that's analyzed properly, not based on pure conjecture or just because someone said so.
