there's a 90's show made in a twighlight zone esque format with short stories played out every episode, i think it was called the outer limits or something. there was an episode of a scientist creating an mrna shot that 'cured everything' he injected a monkey and the monkey was dosed with diseases and radiation, it shook it all off. after the plot carries on the monkey suddenly dies looking like an old monkey. it was determined the mrna shot simply sped the monkeys bodily clock up. it was aging years in only hours, i watched this shortly after the vax hysteria and it definitely fired a couple neurons.
