新突破！我国新冠病毒灭活疫苗获批进入临床试验
<p>国务院联防联控机制科研攻关组表示，我国两款新冠病毒灭活疫苗获得国家药品监督管理局一二期合并的临床试验许可，相关临床试验同步启动。</p><p> 4月10日在国药集团中国生物新冠疫苗生产基地拍摄的新型冠状病毒灭活疫苗样品。此次获批进入临床试验的两款灭活疫苗是我国首批获得临床研究批件的新冠病毒灭活疫苗。此次获批进入临床试验的灭活疫苗是一种杀死病原微生物但仍保持其免疫原性的疫苗，具有生产工艺成熟、质量标准可控、保护范围广等优点。</p><p><span word="They">They</span> <span word="can">can</span> <span word="be">be</span> <span word="used">used</span> <span word="for">for</span> <span word="large">large</span>-<span word="scale">scale</span> <span word="vaccination">vaccination</span>, <span word="and">and</span> <span word="their">their</span> <span word="safety">safety</span> <span word="and">and</span> <span word="effectiveness">effectiveness</span> <span word="can">can</span> <span word="by">by</span> <span word="judged">judged</span> <span word="by">by</span> <span word="internationally">internationally</span> <span word="accepted">accepted</span> <span word="standards">standards</span>.</p><p>这两款疫苗可用于大规模接种，并且有国际通行标准来判断疫苗的安全性和有效性。</p><p>疫苗对疫情防控至关重要。疫情发生以来，国务院联防联控机制科研攻关组专门设立疫苗研发专班，按照灭活疫苗<span word="China">China</span> <span word="has">has</span> <span word="laid">laid</span> <span word="a">a</span> <span word="solid">solid</span> <span word="foundation">foundation</span> <span word="for">for</span> <span word="research">research</span> <span word="in">in</span> <span word="inactivated">inactivated</span> <span word="vaccines">vaccines</span>, <span word="which">which</span> <span word="has">has</span> <span word="been">been</span> <span word="widely">widely</span> <span word="used">used</span> <span word="to">to</span> <span word="fight">fight</span> <span word="hepatitis">hepatitis</span> <span word="A">A</span>, <span word="influenza">influenza</span>, <span word="hand">hand</span>-<span word="foot">foot</span>-<span word="and">and</span>-<span word="mouth">mouth</span> <span word="disease">disease</span> <span word="and">and</span> <span word="poliomyelitis">poliomyelitis</span>.</p><p>我国的灭活疫苗有较好研究基础，甲肝灭活疫苗、流感灭活这两款新冠病毒灭活疫苗分别由国药集团中国生物武汉生物制品研究所、北京科兴中维生物技术有限公司联合有关科研机构开发而成。</p>
