The complete genome sequences of three wild-type measles viruses (genotype D8) isolated from patients in South Korea were determined. These are the first reported complete genome sequences of measles viruses obtained from South Korea, and the availability of these sequences will improve our understanding of measles virus transmission and genetic diversity.

A measles outbreak is affecting the Tel Aviv district, Israel, since April 2012. As of 10 September, 99 cases were confirmed, including 63 (64%) migrants of Eritrean and Sudanese origin. All genotyped cases had the African B3 genotype*. The mean age of migrant and non-migrant cases was 6.0±9.6 and 30.2±24.2 years, respectively (p<0.001). The majority of both migrant and non-migrant cases was unvaccinated. This is the second African measles B3 genotype outbreak within the World Health Organization European region in 2012.

Aim. To study the genetic stability of the measles virus strain Leningrad-16 (L-16) used for the production of vaccine at JSC NPO Mikrogen.Materials and methods. A series of production and sowing strains of L-16 (JSC NPO Mikrogen), ready-made series of measles vaccines from various manufacturers, and the strain of measles virus genotype D6 were studied. Molecular genetic study of the strains was performed using RT-PCR followed by restriction analysis and sequencing.Results. The complete genome sequences of the production and sowing strains of L-16 that are used for vaccine production were obtained. The sequence of the vaccine strain was deposited in GenBank. Strain L-16 was confirmed to be genetically stable. The obtained data demonstrated the possibility of using the RT-PCR method with subsequent restriction analysis to confirm the authenticity of the vaccine strain L-16 in finished mono and three component vaccines.Conclusion. The results of the study suggest the applicability of the molecular genetic methods to confirm the authenticity of the studied strains not only at the production stages, but also in the finished series of vaccines.

H Gene

Measles virus (MeV) genotype B3 is one globally significant circulating genotype. Here, we present a systematic description of long-term evolutionary characterizations of the MeV genotype B3’s hemagglutinin (H) gene in the elimination era. Our results show that the B3 H gene can be divided into two main sub-genotypes, and the highest intra-genotypic diversity was observed in 2004. MeV genotype B3’s H gene diverged in 1976; its overall nucleotide substitution rate is estimated to be 5.697 × 10−4 substitutions/site/year, and is slowing down. The amino acid substitution rate of genotype B3’s H gene is also decreasing, and the mean effective population size has been in a downward trend since 2000. Selection pressure analysis only recognized a few sites under positive selection, and the number of positive selection sites is getting smaller. All of these observations may reveal that genotype B3’s H gene is not under strong selection pressure, and is becoming increasingly conservative. MeV H-gene or whole-genome sequencing should be routine, so as to better elucidate the molecular epidemiology of MeV in the future.

SUMMARYBetween April and July 2011 there was an outbreak of measles virus, genotype D4, in Berlin, Germany. We identified 73 case-patients from the community and among students of an anthroposophic school, who participated in a 4-day school trip, as well as their family and friends. Overall, 27% were aged ⩾20 years, 57% were female and 15% were hospitalized. Of 39 community case-patients, 38% were aged ⩾20 years, 67% were female and 63% required hospitalization. Unvaccinated students returning from the school trip were excluded from school, limiting transmission. Within the group of 55 school-trip participants, including 20 measles case-patients, a measles vaccine effectiveness of 97·1% (95% confidence interval 83·4–100) for two doses was estimated using exact Poisson regression. Our findings support school exclusions and the recommendation of one-dose catch-up vaccination for everyone born after 1970 with incomplete or unknown vaccination status, in addition to the two-dose routine childhood immunization recommendation.
