Overview

SeVRSV is a live-attenuated, recombinant viral vector vaccine candidate designed to provide bivalent protection against respiratory syncytial virus (RSV) and human parainfluenza virus type 1 (hPIV1). Developed by St. Jude Children's Research Hospital, the vaccine utilizes the Sendai virus (SeV)—a murine parainfluenza virus—as a vector to express the RSV fusion (F) protein. Because SeV is antigenically related to hPIV1, the vector backbone itself induces cross-reactive immunity against hPIV1, while the expressed F protein induces neutralizing antibodies and T-cell responses against RSV. The vaccine is typically administered intranasally to stimulate mucosal immunity in the upper respiratory tract, mimicking natural infection to prevent lower respiratory tract disease in infants and children.
