尽管奥密克戎BA.2的毒性较低，但对未接种疫苗的人，特别是老年人的危害严重性较高。

As of May 4, 2022, among the 503 people who died with or from COVID-19, only 25 patients had received at least one dose of COVID-19 vaccine. The vaccination rate for the deceased patients was only 4.97%. 

截至2022年5月4日，在503名死亡病例中，只有25人至少接种了一剂疫苗，接种率仅为4.97%。

文章提出，下一步要做的是：

1、加强医务人员和公众之间的沟通，使所有人都能获得疫苗接种服务，特别是老年人和弱势群体。

2、生产有效的抗新冠病毒药物。

3、充实包括重症监护室和重症监护团队的医疗资源，培训能够为疾病防控提供最后一公里服务的基层医务人员等工作。

The next challenge will be to enhance the communication between the health-care providers and the public to overcome the vaccine hesitancy and make the vaccination service accessible to all people, the older and vulnerable people in particular. Moreover, the production of effective anti-SARS-CoV-2 drugs and preparation of sufficient medical resources, including intensive care units and teams for severe diseases and training of grassroots-level health-care workers capable of last-mile services of disease control and prevention are on the way.
