The findings are indisputable: They are safe and highly effective. Published in The Lancet, the study analyzed extensive global data from clinical trials, laboratory studies, and post-authorization surveillance. It conclusively dispels myths about the technology, emphasizing that mRNA vaccines do not alter human DNA; instead, they temporarily deliver instructions to human cells to recognize viral threats before rapidly breaking down. In terms of protection, the review revealed that mRNA vaccines maintain an outstanding 93% effectiveness against hospitalizations and a 94% effectiveness against mortality shortly after vaccination.Addressing safety, the researchers found that severe adverse events are extraordinarily rare. Serious conditions like heart inflammation (myocarditis and pericarditis) occur in only about 12.6 to 35.6 cases per million doses—a rate significantly lower than the risk of developing these complications from an actual COVID-19 infection. Beyond resolving pandemic-era concerns, this extensive scientific evidence establishes a robust foundation for the future of medicine. The mRNA platform is already being adapted for an array of upcoming clinical trials, offering hope for targeted therapies against seasonal flu, RSV, autoimmune disorders, and various forms of cancer.source: Blakney, A., Top, K., Cowling, B., et al.
