Thakkar and McCarthy suggest that periodicity in measles incidence artifactually drives our estimates of a 2- to 3-year duration of measles "immune-amnesia." We show that periodicity has a negligible effect relative to the immunological signal we detect, and demonstrate that immune-amnesia is largely undetectable in small populations with large fluctuations in mortality of the type they use for illustration.
Thakkar 和 McCarthy 认为麻疹发病率的周期性人为地影响了我们对麻疹“免疫健忘症”持续时间 2 到 3 年的估计。我们表明,相对于我们检测到的免疫信号,周期性的影响可以忽略不计,并且表明在死亡率波动较大的小群体中,免疫健忘症在很大程度上是无法检测到的,而他们正是用这种类型的死亡率来进行说明。
