随着COVID-19大流行进入第二个年头,SARS-CoV-2疫苗有望抑制疾病并恢复到大流行前的正常状态,希望即将到来。在这项研究中,我们批判性地研究了这一希望的基础,使用流行病学建模框架来建立疫苗特性与结束这场前所未有的公共卫生危机的有效性之间的联系。我们的研究结果表明,恢复到大流行前的社会和经济条件而不完全抑制SARS-CoV-2将导致广泛的病毒传播,即使在存在降低感染风险和死亡率的疫苗的情况下,也会造成很高的疾病负担。我们的模型指出了完全抑制SARS-CoV-2的可行性,具有高人口水平的依从性和疫苗,在减少SARS-CoV-2感染方面非常有效。值得注意的是,疫苗介导的传播减少对于病毒抑制至关重要,为了使部分有效的疫苗在SARS-CoV-2抑制中发挥积极作用,必须同时部署补充性生物医学干预措施和公共卫生措施。
As the COVID-19 pandemic drags into its second year, there is hope on the horizon, in the form of SARS-CoV-2 vaccines which promise disease suppression and a return to pre-pandemic normalcy. In this study we critically examine the basis for that hope, using an epidemiological modeling framework to establish the link between vaccine characteristics and effectiveness in bringing an end to this unprecedented public health crisis. Our findings suggest that a return to pre-pandemic social and economic conditions without fully suppressing SARS-CoV-2 will lead to extensive viral spread, resulting in a high disease burden even in the presence of vaccines that reduce risk of infection and mortality. Our modeling points to the feasibility of complete SARS-CoV-2 suppression with high population-level compliance and vaccines that are highly effective at reducing SARS-CoV-2 infection. Notably, vaccine-mediated reduction of transmission is critical for viral suppression, and in order for partially-effective vaccines to play a positive role in SARS-CoV-2 suppression, complementary biomedical interventions and public health measures must be deployed simultaneously.
