Population-level herd immunity is critical for long-term control of SARS-CoV-2. However, proposals to reach the herd immunity threshold through naturally acquired infection, rather than vaccination, have complicated public health efforts and popularized policies that will lead to widespread transmission and mortality. Vaccination is the only viable path to herd immunity.
人群层面的群体免疫对于长期控制 SARS-CoV-2 至关重要。然而，通过自然感染而不是接种疫苗来达到群体免疫阈值的建议使公共卫生工作变得复杂，并使可能导致广泛传播和死亡的政策得到普及。接种疫苗是实现群体免疫的唯一可行途径。
