澳媒:牛津疫苗或帮助澳洲躲过新一轮疫情

《每日邮报》报道称,如果英国的经验有参考意义的话,那么备受非议的牛津-阿斯利康疫苗或许能成为澳洲避免又一次新冠疫情浪潮的关键。

一个又一个欧盟国家在最近对抗新冠疫情的战斗中重新进入封锁状态。随着严冬天 气的到来,整个欧洲大陆都处于红色警报之中。

目前,整个欧洲每天有超过4000人因疫情死亡,俄罗斯、德国、罗马尼亚、波兰、 奥地利和荷兰是受影响最严重的国家。

日新增病例数经常达到大流行早期高峰的两 倍,而且确诊数字仍在上升。 但是自7月以来,英国的死亡人数和新增病例数一直保持相对稳定。

专家们认为, 牛津疫苗可能在其中发挥了关键作用。 墨尔本Hudson研究所名誉所长表示,目前还有更多新冠疫苗正在试验中,有可能应 对任何新的变异菌株,如Omicron。

虽然英国每天的新增病例数大约有40000例,高得令人担忧,但死亡人数已变得相对较少,仅有此前最高病亡人数的十分之一。

英国和澳洲是大规模推广牛津疫苗的两个主要国家。其他大多数国家依靠美国生产 的辉瑞等mRNA疫苗,而中国和俄罗斯则自己生产疫苗。

现在,研究人员正在探索,牛津疫苗是否可能在英国抵御最新一波疫情中发挥了重 要作用。 《每日邮报》报道称,牛津疫苗被怀疑能比其他疫苗引发更长的T细胞反应——免疫过 程的一个重要部分——这可能使其在抵御疫情的长期斗争中更加有效。 但Williams教授也指出,“但这真的很难说,因为英国有大量的人口(约1000万) 感染了病毒,甚至在接种疫苗之前就感染了。”

Williams教授同时警告说,随着防疫限制逐步放松、国境重开以及家庭在圣诞节期 间聚集,澳洲面临着新增病例激增的风险。

但他也相信,大规模疫苗接种已经将疫情对健康的影响降到了最低,最起码目前是这样。

他还指出,在入冬之前,加快推进加强针计划至关重要,呼吁澳人尽快接种第三针。

“我担心的是,我们能凭借高接种率顺利度过夏天。但是到了冬天,人们对病毒的免疫力就会减弱。接种第三剂非常重要。”
