Key result
Rotavirus vaccine introduction shows no evidence of affecting G1P[8] rotavirus population size.
Why the study?
Does rotavirus vaccine introduction affect the genomic evolution and population size of G1P[8] rotavirus strains?

No population size change or strong selection post-vaccination; leaves open whether unique clusters signal early vaccine-driven evolution or natural fluctuation.
Observational (n=157)
Yes
Does rotavirus vaccine introduction affect the genomic evolution and population size of G1P[8] rotavirus strains?
Rotavirus vaccine introduction did not significantly affect the population size of G1P[8] strains, though some unique phylogenetic clusters emerged post-vaccination.
Zeller et al. (2015) conducted an observational in Rotavirus infection (n=157). Rotavirus vaccine introduction vs. Pre-vaccine introduction was evaluated on Rotavirus population size and genomic evolution. Genome-wide evolutionary analysis of 157 G1P[8] rotavirus strains found no evidence that rotavirus population size was affected after vaccine introduction.
