Establishment of a One-Step RT-qPCR Method to Investigate the Biodistribution of a Virus-based Vector Vaccine
Human respiratory syncytial virus (RSV) remains a significant cause of severe respiratory disease, particularly in vulnerable populations such as children and the elderly. With limited effective vaccines available, viral vector vaccines derived from RNA viruses offer promising safety and immunogenicity advantages.
This study describes the method validation of a one-step RT-qPCR to investigate the biodistribution of RNA virus vaccine against RSV in Sprague-Dawley rats after nasal administration. Tissues from key organ systems and blood were collected for analysis. RNA extraction was performed using the Kingfisher Apex, followed by RT-qPCR analysis on the QuantStudio system. Method qualification confirmed robust accuracy, precision, and stability.
