副作用包括疲劳,头痛,发冷和肌肉疼痛

 

辉瑞公司(Pfizer Inc.)高管在周二一次投资者电话会议上表示,在正在进行的后期研究中,使用该公司的试验性新冠疫苗或安慰剂给参与者服用时,主要表现出轻度至中度的副作用。副作用包括疲劳、头痛、发冷和肌肉疼痛。该试验受试者也出现发烧,甚至高烧。由于疫苗临床试验为随机、双盲、安慰剂试验,这意味着辉瑞不知道哪些患者接受了疫苗或安慰剂。

该公司已经在其44000个志愿者试验计划中招募了29000多人,以测试与德国合作伙伴BioNTech合作开发的新冠疫苗。据辉瑞公司披露数据称,目前已有超过12000名研究参与者已经接受了第二剂疫苗。

辉瑞公司表示,正在研究中不断审查这种疫苗的安全性和耐受性。辉瑞公司疫苗组的研究负责人凯瑟琳·詹森(Kathrin Jansen)周二审查了新冠疫苗试验的结论性数据,尽管该数据尚未公布,但一些新数据已经在周二进行了审查。来自当前第3期试验的耐受性数据显示,即使在年龄较大的参与者中,也只有中等程度的令人不愉快的副作用,如头痛和肌肉酸痛。

近期辉瑞公司向投资人更新疫苗管线数据,展示了该公司可能年收入增加200亿美元的产品线。辉瑞疫苗产品在去年416亿美元的销售额中贡献了65亿美元。辉瑞公司将在未来五年内将推出六种新疫苗。辉瑞预计,到2028年,这些新产品和其他新产品将产生其疫苗收入的四分之三,并保护人群达8亿。而且新冠产品甚至并未计入这些预测中。

如果这款新冠疫苗获得批准,辉瑞今年将能够提供1亿剂该型号疫苗,到2021年将再提供13亿剂。美国政府已经订购了4.5亿剂,还有6亿剂的选择权。

在第一波大流行疫苗接种之后,辉瑞公司预计将在2022年推出新冠疫苗的改良版。它还计划针对流感的信使RNA疫苗,其作用将比传统疫苗更广泛、更持久。

此前有报道称,9月6日,辉瑞竞争对手阿斯利康联合牛津大学开发的新冠疫苗试验在英国的受试者中在出现严重副作用,导致在全球范围内暂停试验,在英国监管机构开绿灯后,阿斯利康试验于周一在英国和巴西恢复,但在美国仍被搁置。
