软肋在儿童路透社形容,在可接种人群中,以色列几乎做到应种尽种。若以新冠疫苗覆盖率达80%为形成免疫屏障,“就算全部成年人接种疫苗,以色列可能也无法实现群体免疫。”2月7日,莎伦·阿尔罗伊·普里斯指出,按照新冠疫苗紧急使用授权,该国有250万16岁以下者,不在接种范围内。这约占其总人口的27.8%。当地时间5月26日,以色列国家新冠防疫项目负责人阿什透露,6月后,将启动12-16岁者接种计划。考虑到美国少数青少年接种后报告心脏问题,以色列同年龄段者或将只接种一剂BNT162b2。截至目前,具体接种方案未定。事实上,以色列很早就开始为未成年人接种疫苗做准备。3月,以色列政府分管新冠疫苗接种推广的负责人布阿兹·莱夫称,已为600名12岁-16岁有基础疾病的儿童,接种新冠疫苗BNT162b2。“未发现严重不良反应,轻度不良反应的都很少。这很鼓舞人心。”而美国辉瑞公司透露,新冠疫苗BNT162b2有望在2021年秋,获批用于12岁以下者。其他制药企业也在开展相关研究。2020年12月,美国莫德纳公司启动12岁以上者的临床试验。“还有一个变数。病毒变异株或降低疫苗保护效力。”《耶路撒冷邮报》报道,5月3日,以色列卫生部发表公告,从国外返回以色列的人中,一名婴儿和一名已接种过新冠疫苗的成年人确诊感染首现于巴西的变异株,另一名已接种过疫苗的成年人感染了首现于智利的变异株。“迄今为止,通过大规模接种疫苗中断病毒传播,已使所有年龄段的发病率持续下降。但,随着非药物干预措施(如戴口罩、社交隔离)逐步削弱,部分地区疫苗接种率低,以及变异株潜在风险,暴发风险依然存在。大流行尚未结束,以色列仍需保持警惕。”《科学》杂志称。资料来源:1.Israel to end COVID-19 restrictions after vaccine success.
