There is no evidence of interference by the RV1 vaccine in the evolution of the 11 genes from Brazilian strains G1P[8] genotype over a 27-year period. P[8] lineages chronology in Brazil

RV1: P[8]-1 Most recent strains: P[8]-3
Silva et al., 2013 P[8]-3.2
P[8]-3.4
P[8]-3.6
P[8]-3.1 P[8]-3.3
P[8]-3.5 Conclusions: A clear shift in RVA genotypes distribution was observed between 2006 – 2013 in different countries.
G and P genotyping still important to characterize RVA strains.
There is no evidence of interference of P[8]-3 sub-lineage in the effectiveness of RV1.
There is no evidence of interference by the RV1 vaccine in the evolution of the 11 genes from Brazilian strains G1, G2, G3, G9, and G12.
Epidemiological information – vaccination data / status – is very important, as well as age, severity of infection etc..
