Tetanus is a disease caused by tetanus toxin, a potent inhibitor for the release of inhibitory neurotransmitter in the central nervous system that causes spastic paralysis. Fragment C (52 kD) of this toxin is responsible for binding to the neuronal membrane. For this reason, and also its non toxigenic and immunogenic nature, this fragment might be ideal for new vaccine development. Presently, w...

considering the circulation of bordetella pertussis clinical strains among populations with high vaccination coverage, it is necessary to have a proper understanding of this bacterium causing whooping cough. various techniques, which are available for studying b. pertussis, can facilitate a proper comparison between different populations. we genotypically analyzed a collection of two vaccine st...

OBJECTIVES Effective vaccines against the highly pathogenic influenza A/H5N1 virus are being developed worldwide. In Japan, two adjuvanted, inactivated, whole-virion influenza vaccines were recently developed and licensed as mock-up, pre-pandemic vaccine formulations by the Ministry of Health and Labor Welfare of Japan. During the vaccine design and development process, various obstacles were o...

Antibody production in mice after immunization with diphtheria-pertussis-tetanus (DPT) vaccine was investigated. Six lots of the vaccine produced in the same year by six manufacturers in Japan were chosen. Production of IgE antibody specific to either diphtheria or tetanus toxoid varied among vaccine preparations used, although there was no apparent difference in IgG antibody production after i...

Background and Aims: The safe, potent and effective live vaccines against Measles, Mumps and Rubella as important childhood diseases have been available for several decades. Several factors can affect the thermal stability of lyophilized vaccine. Methods: In this study, the effect of residual moisture on thermal stability of 61 batches of MMR vaccine was investigated using an accelerated ...

with advent and development of dna recombinant technology and advantages of p. pastoris expression system, fusion (f) protein of pprv expression, because of effective immunodominant role could be an appropriate candidate for production of recombinant vaccine against ppr disease. in this study, f gene of pprv nigeria 75/1 strain (1637 bp) was amplified using rt-pcr and purified. it was then clon...
