Modified Sendai virus vaccine and imaging vector (SJ-11-0018)

St. Jude Reference #SJ-11-0018


Researchers at St. Jude have developed a genetically modified Sendai Virus for use as a two-for-one vaccine against respiratory syncytial virus (RSV, a cause of serious lung disease in young children) and parainfluenza virus type 1 (hPIV-1, a cause of croup in young children). The vaccine, named SeVRSV, has proven safe and effective [1]. The vaccine vector elicits both B cell and T cell activities [2]. Because the vaccine vector is administered by the intranasal route, it can elicit durable immune responses in the upper respiratory tract to stop a human infection at the pathogen’s site of entry [3]. The vaccine was well-tolerated in an adult clinical study at Cincinnati Children’s Hospital Medical Center, supported by the Division of Microbiology and Infectious Diseases at the National Institutes of Health [4]. The SeVRSV backbone (unmodified Sendai Virus) was also tested in clinical trials, and was well tolerated in adults [5], seropositive 3-6 year olds [6], and seropositive 1-2 year olds. Future plans include the testing of both unmodified Sendai virus and SeVRSV in seropositive and then seronegative children, the latter being the pediatric population that is most vulnerable to RSV and hPIV-1 infections. Our two-for-one vaccine, once proven effective in humans, may save tens of thousands of pediatric lives each year worldwide.
