We measured antibody binding to diverse norovirus virus-like particles over 12 months in 16 children. All had maternal antibodies at 2 months, with estimated lowest levels at 5 months of age. Antibody increases after 3 months suggested natural infections. This information could guide the timing of future norovirus vaccines.

生命第一年人类诺如病毒特异性抗体的广度和动态。

我们在 12 个月的时间里测量了 16 名儿童的抗体与多种诺如病毒病毒样颗粒的结合。所有人在 2 个月大时都有母体抗体，估计在 5 个月大时水平最低。3个月后抗体升高提示自然感染。该信息可以指导未来诺如病毒疫苗的上市时间。
