目的为摸清冻干水痘减毒活疫苗的免疫效果,针对水痘的发病特点,制订下一步防治策略,分析儿童水痘疫苗接种的经济效益,更好地开展防治工作。方法对胜利油田胜南社区部分健康易感儿童进行疫苗接种,并随机抽取接种疫苗5个月后的儿童抽取血样送胜利油田CDC开展抗体水平监测。采用成本效益分析方法计算效益费用比(BCR)。结果 500名观察对象接种水痘疫苗后无明显副反应。检测有效血清210份,血清抗体(vzviGg)阳转率为97.5%以上,保护对象无一发病。水痘疫苗接种后成本经济效益相当高。结论不同代次、不同剂量的国产水痘疫苗副反应率较低,免疫效果好。接种国产冻干水痘减毒活疫苗安全、有效,可作为预防水痘的首选。
Objective To find out the immune effect of the live attenuated freeze-dried varicella vaccine, according to the incidence of chickenpox, formulate the next prevention and control strategy, analyze the economic benefits of vaccination of children with chickenpox and better carry out prevention and treatment work. Methods Vaccination of some healthy and susceptible children in Shengnan community of Shengli Oilfield and random sampling of children after 5 months of vaccination to collect blood samples from CDC of Shengli Oilfield for antibody level monitoring. Cost-benefit ratio (BCR) is calculated using a cost-benefit analysis. Results 500 subjects were vaccinated with chickenpox without significant side effects. Test positive serum 210 copies, serum antibody (vzviGg) positive rate of 97.5%, no protection of the disease. Costs of chickenpox vaccination are quite cost-effective. Conclusion Different generations and different doses of domestic varicella vaccine have low side reaction rate and good immunological effect. Inoculation of domestic freeze-dried varicella live attenuated vaccine is safe and effective, as the first choice for the prevention of chickenpox.
