by Gertrud U. Rey On October 2nd, 2023, the Nobel Assembly at Karolinska Institutet announced the award of the 2023 Nobel Prize in Physiology or Medicine to Katalin Karikó and Drew Weissman. The decision was based on a series of fundamental discoveries that led to the development of the COVID-19 messenger RNA (mRNA) vaccines. Katalin …
by Gertrud U. Rey Almost sixty years have passed since the initial formalin-inactivated respiratory syncytial virus (RSV) vaccine caused enhanced disease in children when they were subsequently infected with the virus. Since then, RSV has continued to be a substantial public health threat to infants, young children, and older people. Although progress in developing a …
