| description | Preparation of the indigenous varicella zoster vaccine could significantly reduce the disease burden of varicella zoster virus especially in immunosuppressed children. To achieve this goal, the varicella zoster virus was isolated from an 8 years boy infected with chicken pox. The virus was cultivated in sensitive cell line and determined varicella zoster. The adaptation and attenuation of virus was carried out after several passages in MRC-5 cell culture, Primary Guinea pig embryo fibroblast cell culture and again switching in MRC-5 cell culture. The challenged of vaccine dose was found 3LogCCID50. Following two doses of immunization in guinea pigs via inoculated cell culture-fluid attenuated- local isolated VZV at zero and 14 day, the humoral immune response, varicella-zoster virus (VZV) IgG and IgM were determined using enzyme-linked Immunosorbent and seroneutralization assays at 7, 14, 21, 30, 60, 90.120 days after receiving of the first and second dose of vaccine. The results of immunization showed good 93% seroconversion in guinea pig which compared with vOKa vaccine was not significant (p<0.05). The prepared attenuate varicella zoster virus promising a candidate Virus for our future plan to vaccine production. |
