Overview

A **recombinant nanoparticle vaccine** composed of the respiratory syncytial virus (RSV) fusion (F) glycoprotein, engineered as nanoparticles. The F protein mediates fusion of RSV with host cells, and the vaccine aims to induce strong antibody responses, especially targeting neutralizing sites such as antigenic site II. The vaccine is being developed primarily for **maternal immunization** to prevent RSV infections in infants by transferring RSV-specific antibodies, as well as for older adults. In clinical studies, the vaccine has shown to be safe, immunogenic, and resulted in reduced evidence of RSV infection rates in vaccinated subjects compared to placebo[6]. Several formulations (with or without adjuvants, single-dose and two-dose regimens) have been tested. Developer: Novavax[2][6] Primary indication: **Prevention of RSV infection** and RSV-associated lower respiratory tract disease in infants (via maternal immunization) and older adults.
