About Event
We examine the relevance of the ubiquitous inequality, p > 1 – 1/R0, giving the necessary proportion p of individuals to be vaccinated in order to prevent further substantial outbreaks. This inequality comes principally from the celebrated SIR model of Kermack and McKendrick. Considering models that take into account imperfect vaccination and temporary immunity, we show that this inequality does not stand and p must satisfy a stronger and more complicated condition. We give some examples with parameters close to those estimated for COVID-19.

He obtained his Doctorate in Mathematics from the University of Metz, France, in 1992, and his Habilitation à Diriger des Recherches (HDR) from the University of Nice in 2010. His research interests include the control theory (stabilization of nonlinear systems, observability, and construction of observers), the mathematical epidemiology (modelling and model validation using data, qualitative and quantitative properties of epidemics models, design of software sensors for biological systems, dynamical estimation of unmeasured state variables and unknown parameters, etc.), and the modelling and control of renewable resources.
