The Flu vax got eviscerated when the UK data was released that showed essentially 0 drop in fatalities from it through the transition of the 64-65 YO group there. If it was even remotely effective there should have been a noticeable downtick in death because apparently it’s highly pushed or mandatory under their health system for 65 and older. Through 170 million data points its a flat line through it...
AFAIC the entire vax industry is useless at best, and very harmful at worst. Except rabies or tetanus, if one is at risk, like a veterinarian. Tetanus has no cure and it is a horrible way to die.
