Nobel Prize for Medicine to Karikó and Weissman: the turning point of mRNA vaccines

Listen to the audio version of the article

The Hungarian Katalin Karikó and the American Drew Weissman are the scientists awarded the 2023 Nobel Prize for Physiology and Medicine, for having laid the foundations for the messenger mRNA vaccines that made the anti-Covid-19 vaccines possible. The announcement was made in Stockholm by Thomas Perlmann, secretary of the Nobel Assembly. Their studies were the basis for a turning point in the fight against a threat to human health unprecedented in recent history and promise extraordinary developments for the treatment of other diseases.

The significant potential of technology

«The approval of two effective and safe mRNA vaccines against Covid-19 at the end of 2020 pushed the field of mRNA vaccines into a new era. The discovery that the use of modified bases in in vitro transcribed mRNA circumvents unwanted inflammatory responses and increases protein production after in vivo delivery demonstrates the value of basic research.” The results published by Karikó and Weissman in their seminal 2005 paper received little attention at the time, but they laid the foundation for critically important developments that have served humanity well during the Covid pandemic, we read in the motivations, in which it is underlined that «the widespread use of the two Covid-19 mRNA vaccines in recent years demonstrates the significant potential of this technology and shows that serious adverse effects of the two authorized mRNA vaccines were exceptionally rare, providing a solid basis for future applications». According to expectations, possible future applications include vaccines against infections and cancer.
