About
Icosavax was a clinical-stage biopharmaceutical company that developed next-generation vaccines using computationally designed virus-like particle (VLP) technology, originally spun out of the University of Washington Institute for Protein Design in 2018. The company's platform enabled the engineering of synthetic nanoparticles that closely mimic natural viruses to elicit potent immune responses, with lead programs targeting RSV and hMPV. Icosavax's VLP-based approach offered a differentiated alternative to mRNA and traditional vaccine modalities. The company was acquired by AstraZeneca in early 2024 for approximately $1.1 billion.
