normal;box-sizing: border-box;">未成年人新冠疫苗开放接种姗姗来迟的原因有很多，其中之一便是，<strong style="box-sizing: border-box;">儿童并不是最高危的易感人群</strong>。</p><p style="white-space: normal;box-sizing: border-box;"><br style="box-sizing: border-box;"/></p><p style="white-space: normal;box-sizing: border-box;">虽然与成年人相比，仍然有小部分未成年人感染新冠病毒后面临着发展为重症的风险，但大多数临床表现通常为轻度或无症状。例如，最近在东南亚和南亚发表的一项观察研究 7 个国家的医院报告显示，在确诊的儿童中，无症状的比例为 40%。 </p><p style="white-space: normal;box-sizing: border-box;"><br style="box-sizing: border-box;"/></p><p style="white-space: normal;box-sizing: border-box;">曾发表在《柳叶刀》上的一项针对七国的研究估计，在大流行期间，每 100 万名儿童中，死于新冠的儿童不到 2 名。</p><p style="white-space: normal;box-sizing: border-box;"><br style="box-sizing: border-box;"/></p><p style="white-space: normal;box-sizing: border-box;">因此年长者作为更高危的人群，优先获得了接种权。</p><p style="white-space: normal;box-sizing: border-box;"><br style="box-sizing: border-box;"/></p><p style="white-space: normal;box-sizing: border-box;"><strong style="box-sizing: border-box;">此外，儿童接种疫苗后的风险与不确定性更高，也是推迟开放接种的原因之一。</strong></p><p style="white-space: normal;box-sizing: border-box;"><br style="box-sizing: border-box;"/></p><p style="white-space: normal;box-sizing: border-box;">尽管如此，儿童依然有感染 COVID-19 病毒的风险，依然有可能因感染 COVID-19 而生病；感染后作为无症状感染者，也更容易悄无声息的将 COVID-19 传播给他人。</p></section></section></section></section><section style="box-sizing:

月公布疫苗试验初步结果，结果显示，接种新冠疫苗组（n=1131）中没有出现新型冠状病毒肺炎病例。</p><p style="white-space: normal;box-sizing: border-box;">基于此，美国食品药物监督管理局（FDA）批准辉瑞疫苗的使用范围扩大到 12～15 岁的未成年人群，争取让千百万美国的初中和高中生在秋季返校前接种疫苗。</p><p
