当前百日咳疫苗可能会让你或你的孩子保持健康,但它也许并不能阻止人与人之间的疾病传播。研究人员发现,狒狒即使注射了疫苗,仍然会携带和传播这种病毒。这项研究中越来越多的证据表明:在百日咳疫苗中,只有一部分百日咳杆菌注入血液中会引起保护性免疫反应。相比全细胞疫苗而言,这种疫苗对疾病的控制表现不佳。然而,疫苗制造商认为,得出类似的效果会出现在人类身上的结论还为时尚早。
The current pertussis vaccine may keep you or your child healthy, but it may not stop the spread of the disease between people. Researchers found baboons carry and spread the virus even with a vaccine. More and more evidence from this study shows that in the pertussis vaccine, only a small percentage of Bordetella pertussis injected into the blood can cause a protective immune response. This vaccine performs poorly on disease control over whole-cell vaccines. However, vaccine manufacturers think it is too early to conclude that similar effects will occur in humans.
