有数据表明 ,某些疫苗在发达国家儿童中诱导的免疫应答强于发展中国家 ,可能是发展中国家儿童的营养状况较差造成的。维生素 A( Vit A)、锌 ( Zn)等微量营养素对免疫活性起重要作用 ,而发展中国家儿童普遍微量营养素缺乏。本研究检测了补充微量营养素能否增强儿童口服霍乱灭活?
Some data indicate that some vaccines induce a stronger immune response in children in developed countries than in developing countries, possibly due to the poor nutritional status of children in developing countries. Micronutrients such as Vit A and Zn play an important role in immunocompetence while children in developing countries generally suffer from micronutrient deficiencies. This study examined whether supplementation with micronutrients could enhance the inactivation of oral cholera in children.
