One study I saw, which reviewed data on four thousand people, and only looked at those who had gotten the fourth booster. Their all-cause death rate dropped for three months, then spiked well above the all-cause rate of those who had not gotten a fourth booster.
This mRNA approach is like smacking the side of a tube television to improve the picture. Sometimes it works and no one knows why. Sometimes it doesn’t.
Except that no one can prove the mRNA shots work other than causing turbo cancers, strokes, extreme cell development inside blood vessels, and myocarditis.
