ZURICH/FRANKFURT : Breakthrough technology that transforms the body into a virus-zapping vaccine factory is poised to revolutionise the fight against COVID-19 but future pandemics and even cancer could be next, scientists say.The initial success of so-called messenger ribonucleic acid (mRNA) vaccines in late-stage trials by Moderna as well as Pfizer and its German partner BioNTech is the first proof the concept works.Both experimental vaccines had efficacy rates above 90% based on interim findings, which was far higher than expected and well above the 50% threshold U.S.
regulators insist upon for vaccines.Now scientists say the technology, a slow-motion revolution in the making since the discovery of mRNA nearly 60 years ago, could speed up.
