Vaccination control of an epidemic model with time delay and its application to COVID-19 |pdf=|usr=}}{{34092918}} gab.com Text Vaccination control of an epidemic model with time delay and its application to COVID-19 JO: Nonlinear Dyn http://www.kidney.de/pget.php?&tw=1&pmid=34092918 #FOAvip This paper studies an SEIR-type epidemic model with time delay and vaccination control. The vaccination control is applied when the basic reproduction number R0 > 1 . The vaccination strategy is expressed as a state delayed feedback which is related to the current and previous state of the epidemic model, and makes the model become a linear system in new coordinates. For the presence and absence of vaccination control, we investigate the nonnegativity and boundedness of the model, respectively. We obtain some sufficient conditions for the eigenvalues of the linear system such that the nonnegativity of the epidemic model can be guaranteed when the vaccination strategy is applied. In addition, we study the stability of disease-free equilibrium when R0 < 1 and the persistent of disease when R0 > 1 . Finally, we use the obtained theoretical results to simulate the vaccination strategy to control the spread of COVID-19.
