Fase 1/2a-studie van BLB-201-vaccin bij RSV-seronegatieve en seropositieve zuigelingen en kinderen
Een fase 1/2a-onderzoek naar de veiligheid, verdraagbaarheid en immunogeniciteit van RSV-vaccin met PIV5-vector (BLB-201) bij RSV-seronegatieve en seropositieve zuigelingen en kinderen
This Phase 1/2a trial is a randomized, placebo-controlled trial to evaluate the safety, tolerability and immunogenicity of two ascending doses (10^6 PFU and 10^7 PFU) of intranasal BLB-201 (a recombinant parainfluenza virus type 5) administered in infants (8-24 months of age) and children (18-59 months of age) who may or may not have had prior respiratory syncytial virus (RSV) infection.

Gedetailleerde beschrijving
This trial is designed to evaluate the safety, tolerability and immunogenicity of BLB-201 vaccine in infants (8-24 months of age) and children (18-59 months of age) who may or may not have had prior respiratory syncytial virus (RSV) infection. One (Day 1) or two doses (Day 1 and Day 57) of low (10^6 PFU) and high dosage (10^7 PFU) of BLB-201 will be evaluated.
