Computationally Designed VLP Vaccines

By utilizing computationally designed proteins that self-assemble into virus-like particles (VLPs), we are able to readily manufacture VLPs displaying complex antigens to target significant unmet medical needs.

RSV and Covid-19 Vaccines

Our vaccine candidates for respiratory syncytial virus (RSV) and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes COVID-19, have the potential to induce high neutralizing antibody titers for more effective protection.

Icosavax is dedicated to advancing vaccines against severe life-threatening respiratory diseases to protect our most at-risk populations.
