Distribution of Rotavirus Genotypes After Introduction of Rotavirus Vaccines, Rotarix® and RotaTeq®, into the National Immunization Program of Australia

Abstract

Differences in rotavirus genotypes were observed across Australia, which suggest that different immune pressures are exerted by the different vaccines, but do not necessarily imply lack of protection by either vaccine. These differences may simply be related to the variation that can occur because of natural annual fluctuation in rotavirus strain prevalence.
