Despite a safe and effective vaccine, endemic rubella remains a problem in developing countries. Isolated cases and outbreaks can occur in areas with high vaccine coverage. Individuals, especially pregnant women who remain unimmunized or do not seroconvert, are susceptible to infection and their infants are at risk for congenital rubella syndrome (CRS). Both humoral and cellular immune responses contribute to immune protection. Classically, immunity to rubella has been assessed through the detection of rubella-specific antibody titers. In this study we examined correlates of both humoral and cellular immunity in a large population of immunized young adults in Olmsted County, MN. We were unable to find any significant correlation between cytokine production after in-vitro rubella stimulation and serum antibody titers.
尽管有安全有效的疫苗,但地方性风疹在发展中国家仍然是一个问题。在疫苗覆盖率高的地区,可能会出现散发病例和暴发。未接种疫苗或未产生血清转换的个人,尤其是孕妇,容易受到感染,其婴儿有患先天性风疹综合征(CRS)的风险。体液和细胞免疫反应都有助于免疫保护。传统上,通过检测风疹特异性抗体滴度来评估对风疹的免疫力。在这项研究中,我们在明尼苏达州奥姆斯特德县的一大群免疫接种的年轻成年人中检查了体液和细胞免疫的相关性。我们未能发现体外风疹刺激后细胞因子产生与血清抗体滴度之间存在任何显著相关性。
