Benjamin Mueller and Gina Kolata in The New York Times:
Katalin Karikó and Drew Weissman, who together identified a chemical tweak to messenger RNA, were awarded the Nobel Prize in Physiology or Medicine on Monday. Their work enabled potent Covid vaccines to be made in less than a year, averting tens of millions of deaths and helping the world recover from the worst pandemic in a century.
The approach to mRNA the two researchers developed has been used in Covid shots that have since been administered billions of times globally and has transformed vaccine technology, laying the foundation for inoculations that may one day protect against a number of deadly diseases like cancer. The slow and methodical research that made the Covid shots possible has now run up against a powerful anti-vaccine movement, especially in the United States. Skeptics have seized in part on the vaccines’ rapid development — among the most impressive feats of modern medical science — to undermine the public’s trust in them. But the breakthroughs behind the shots unfolded little by little over decades, including at the University of Pennsylvania, where Dr. Weissman runs a lab.
