Measles vaccine virus RNA in children more than 100 days after vaccination

The sequenced region is the World Health Organization (WHO)-recommended 450nt nucleoprotein (N) gene fragment encoding the carboxyl-terminal of the gene.WHO MeV reference strain sequences include GenBank accession numbers and by eight clades designated A­­–­H. MeVV sequences associated with patients are indicated by case number and associated GenBank accession number. Phylogenetic analysis used the Neighbor-Joining method Maximum Composite Likelihood methods was performed in MEGA7 with a bootstrap analysis of 1000 replicates. The percentage of replicate trees in the bootstrap test (1000 replicates) greater than 85 are shown next to the branches.
