Real-time RT-PCR assay for Detection of Live Attenuated Influenza Vaccine for A and B Viruses
Upon intranasal vaccination, live attenuated influenza vaccine (LAIV) viruses may replicate within the nose for several days. Current clinical diagnostic tests cannot distinguish between LAIV viruses and multiple influenza viruses in recently inoculated patients that present with respiratory symptoms. This poses a problem for the diagnosis and treatment of patients with respiratory symptoms, as these symptoms may not be caused by influenza. CDC researchers have developed a real-time RT-PCR assay to detect the presence of LAIV viruses.
