rabies is a fatal neurological disease and a persistent global problem. it is spread primarily by domestic dogs but other canid, viverrid (skunks and raccoons) and chiropteran species are considered as the most efficient vectors of the disease. since dogs are the main perpetuator of rabies, special attention has to be given to bring all the dogs including unauthorized stray dogs under immunizat...
Background: Today, several vaccines have been developed to prevent infectious diseases. The older first-generation vaccines may have many problems. In this regard, genetic engineering plays an important role using tools such as shuttle vectors to develop recombinant DNA vaccines that usually include plasmid constructed so that can propagate in two different host species. The present study revie...
Diploid and continuous cell lines are used to propagate viral vaccines. At Human Viral Vaccine Department of Razi Vaccine and Serum Research Institute, MRC5 diploid cell is used for the development of live attenuated measles, mumps, rubella, and three types of poliovirus vaccines. Additionally, three continuous cell lines (i.e., RK13, HeLa, and Vero) are applied in quality control tests. Accor...
Background: The World Health Organization (WHO) has recommended the cell culture based rabies vaccines have no significant side effects. PVRV is a type of cell culture based vaccine, which is used for human rabies vaccination in Iran. Because PVRV is produced by a single source provider; other cell-culture derived vaccines, PCECV, has recently been used for vaccination. Methods: In this dou...
the plaque forming unit (pfu) and tissue culture infectious dose50 (tcid 50 ) methods are used for evaluation of vaccine heat stability and effect of various stabilizers on thermal stability of vaccines. the aim of present study is using real-time pcrtechniquefor estimation of vaccine degradation rate and thermal stability of measles vaccines. lyophilized measles vaccines containing three vario...
background and aims: adventitious agents, especially viral agents are among the most important concerns in viral vaccines. viral contamination of biological products may arise from the original source of the reagents such as, serum, trypsin, animal or human derived media components or cell culture and working seed or cross contamination of vaccine during production. in this study, adventitious ...
