Nobel Prize in medicine for scientists who paved the way for COVID vaccines

Stockholm: Two scientists won the Nobel Prize in medicine on Monday for discoveries that enabled the development of mRNA vaccines against COVID-19 and could be used in the future to create other shots.

Katalin Karikó, a professor at Sagan’s University in Hungary and an adjunct professor at the University of Pennsylvania, and Drew Weissman, of the University of Pennsylvania, were awarded the prize for “their groundbreaking findings, which have fundamentally changed our understanding of how mRNA interacts with our immune system”, the panel that awarded the prize said.

“The laureates contributed to the unprecedented rate of vaccine development during one of the greatest threats to human health in modern times,” the panel added.

Thomas Perlmann, secretary of the Nobel Assembly, announced the prize and said both scientists were “overwhelmed” by news of the prize when he contacted them shortly before the announcement.

Traditionally, making vaccines required growing viruses or pieces of viruses — often in giant vats of cells or, like most flu shots, in chicken eggs — and then purifying them before next steps in brewing shots.

The messenger RNA approach is radically different. It starts with a snippet of genetic code that carries instructions for making proteins. Pick the right virus protein to target, and the body turns into a mini vaccine factory.

Dr Paul Hunter, a professor of medicine at Britain’s University of East Anglia, described the mRNA vaccines as a “game changer” in helping to shut down the coronavirus pandemic, crediting the shots with saving millions of lives.

“If it hadn’t been for the mRNA technology, COVID would have been much worse,” he said.
