Genomic Analysis of Rwandan G9P[8] Rotavirus Strains Pre- and Post-RotaTeq^® Vaccine Reveals Significant Distinct Sub-Clustering in a Post-Vaccination Cohort.

ABSTRACT: Although the introduction of rotavirus vaccines has substantially contributed to the reduction in rotavirus morbidity and mortality, concerns persist about the re-emergence of variant strains that might alter vaccine effectiveness in the long term. The G9 strains re-emerged in Africa during the mid-1990s and have more recently become predominant in some countries, such as Ghana and Zambia. In Rwanda, during the 2011 to 2015 routine surveillance period, G9P[8] persisted during both the pre- and post-vaccine periods. The pre-vaccination cohort was based on the surveillance period of 2011 to 2012, and the post-vaccination cohort was based on the period of 2013 to 2015, excluding 2014. The RotaTeq^® vaccine that was first introduced in Rwanda in 2012 is genotypically heterologous to
