英国卫生部近日草拟了一份长期计划,用以防止儿童免疫疫苗的严重短缺。在一份交给英国议会的报告中,国家审计办公室(NAO)称为数有限的疫苗公司和大型医药企业进入了周期性的疫苗短缺阶段,目前他们缺乏许多致命性疾病的疫苗。 The British Ministry of Health recently drafted a long-term plan to prevent a serious shortage of children’s immunization vaccine. In a report to the British Parliament, the National Audit Office (NAO) said that a limited number of vaccine companies and large pharmaceutical companies have entered a period of cyclical vaccine shortages, and now they lack many deadly disease vaccines.
