| Emergence and Continuous Evolution of Genotype 1E Rubella Viruses in China. | In China, rubella vaccination was introduced into the national immunization program in 2008, and a rubella epidemic occurred in the same year. In order to know whether changes in the genotypic distribution of rubella viruses have occurred in the post-vaccination era, we investigate in detail the epidemiological profile of rubella in China, and estimate the evolutionary rate, molecular clock phylogeny, and demographic history of the predominant rubella virus genotypes circulating in China using B ... | 2011 | 22162559 |
