The impact of vaccination and boinfection on HPV and cervical cancer
(American Institute of Mathematical Sciences, 2009-09)
Understanding the relationship between coinfection with multiple strains of human papillomavirus and cervical cancer may play a key role in vaccination strategies for the virus. In this article we formulate a model with ...
Vaccination strategies and backward bifurcation in age-since-infection structured model
We consider models for a disease with acute and chronic infective stages, and variable infectivity and recovery rates, within the context of a vaccination campaign. Models for SIRS and SIS disease cycles exhibit backward ...
Effects of education, vaccination and treatment on HIV transmission in homosexuals with genetic heterogeneity
Genetic studies report the existence of a mutant allele Δ32 of CC R5 chemokine receptor gene at high allele frequencies ( 10%) in Caucasian populations. The presence of the allele is believed to provide partial or full ...
A simple vaccination model with multiple endemic states
A simple two-dimensional SIS model with vaccination exhibits a backward bifurcation for some parameter values. A two-population version of the model leads to the consideration of vaccination policies in paired border towns. ...
