Sequence Variation in Measles Virus F Gene of AIK-C Vaccines Strain after Passage in Vero Cells

Construction of a Minigenome Rescue System for Measles Virus, AIK-c Strain

Background:In the recent decade, the reverse genetics method has been broadly used for rescue of negative-stranded RNA viruses from cDNA or viral minigenomes. This technique has been applied to study different steps in virus replication and virus-host interactions. Reverse genetics could also be implemented for design of new vaccines. The T7 RNA polymerase activity as well as virus (nucleocapsi...

Stability Study of Measles AIK-C Strain, Mumps RS-12 Strain and Rubella Takahashi Strain in MMR Vaccine

Stability studies play a critical role in assuring product quality at all points in the vaccine life cycle and havea major impact on the success of immunization programs worldwide. The purpose of stability study isdetermination of the vaccine quality under the variety of environmental factors and to establish a re-testperiod or a shelf life and recommended storage conditions. In this study thre...

Recombinant Measles AIK-C Vaccine Strain Expressing the prM-E Antigen of Japanese Encephalitis Virus

An inactivated Japanese encephalitis virus (JEV) vaccine, which induces neutralizing antibodies, has been used for many years in Japan. In the present study, the JEV prM-E protein gene was cloned, inserted at the P/M junction of measles AIK-C cDNA, and an infectious virus was recovered. The JEV E protein was expressed in B95a cells infected with the recombinant virus. Cotton rats were inoculate...

Increased binding activity of measles virus to monkey red blood cells after long-term passage in Vero cell cultures.

Recent field isolates of measles virus (MV) obtained by using B95-8 cells have been reported not to agglutinate African green monkey red blood cells (AGM-RBC). Vero cell-adapted, plaque-forming strains derived from three field isolates at the third passage in Vero cell cultures (T8Ve-3, T11Ve-3 and N13Ve-3) also exhibited markedly decreased binding activity, as determined by infectivity-absorpt...
