Rotavirus Vaccine

Detection of vaccine-derived rotavirus strains in nonimmunocompromised children up to 3-6 months after RotaTeq vaccination
We conducted a survey on the presence of RotaTeq vaccine viruses in infants hospitalized with respiratory infection, and detected shedding in 17% of children (<2 years of age) who had ever received the vaccine. The latest detection was at the age of 8 months. We conclude that asymptomatic long-time shedding of RotaTeq viruses is not uncommon, and is particularly associated with genotype G1.
