Jason S. McLellan, The University of Texas at Austin, received the 2023 NAS Award in Molecular Biology.

McLellan has made exceptional contributions to public health and medicine through his groundbreaking work on the molecular biology and structure of viral glycoproteins as applied to vaccine antigen design.

McLellan pioneered the use of atomic-resolution structures to guide design of effective vaccines. These structural studies of proteins from human viral pathogens illuminate infection mechanisms while directly informing design of vaccines and therapeutics. His work has been instrumental to the development of successful vaccines against respiratory syncytial virus (RSV) and SARS-CoV-2 and are playing a key role in the development of vaccines and therapeutics targeting an array of additional pathogens. 

The NAS Award in Molecular Biology is supported by Pfizer Inc. and recognizes a recent notable discovery by a young scientist who is a citizen of the United States. The award is presented with a medal and a $25,000 prize.
