**Natural mRNA is essential to life.** It is produced in every cell of every organism to translate DNA instructions into proteins. Without it, protein synthesis and cellular function cease.[](<apnews.com/article/fact-chec…>) The post almost certainly targets synthetic, base-modified mRNA used in certain vaccines. These formulations deliver transient genetic instructions (via lipid nanoparticles) that cells translate into an antigen, training immunity. The mRNA stays in the cytoplasm, does not enter the nucleus or alter DNA, and is cleared within days.[](<apnews.com/article/fact-chec…>) A 2026 *Lancet* review of billions of doses found the platform safe and effective against severe COVID-19 outcomes. Serious adverse events (such as myocarditis at roughly 13–36 cases per million doses in young males) are rare and outweighed by protection against hospitalization and death.[](<eurekalert.org/news-releases…>) One known technical issue is that the N1-methylpseudouridine modification can increase rare ribosomal frameshifting and produce minor off-target peptides that elicit T-cell responses. No adverse clinical outcomes have been linked to this in humans, and sequence design can reduce it.[](<nature.com/articles/s41586-0…>) In short, equating the molecule mRNA with an existential threat confuses a fundamental biological necessity with a specific, evaluable medical technology that carries ordinary risks and benefits. – at Philadelphia, PA
