摘要
接种策略对阻止和控制流行病传播起着重要作用,考虑接种疫苗年龄和暂时免疫力在现实中更为合理.讨论具有接种疫苗年龄和暂时免疫的SEIVS流行病模型的稳定性,给出阈值条件,证明模型平衡点存在性与稳定性.
Vaccination strategy plays an important role in preventing and controlling the spread of the epidemic. It is more reasonable to consider vaccination-age and temporary immunity in reality. This paper studied the stability of an SEIVS epidemic model with vaccination-age and temporary immunity,gave the threshold condition and proved the existence and stability of equilibrium.
