Vaccination strategies for a seasonal epidemic: a simple SIR model

We model the effect of vaccination on an epidemic which, like current one, exhibits a climate-induced seasonality. Our study is carried out using simple SIR model. One important feature our approach that recruitment: by gradually introducing susceptible individuals we mimic spatial evolution epidemic, which absent in classic SIR. focus number hospital admissions. show any delay campaign results increase hospitalisations, and if one tries to palliate for increasing rate, this inflation necessary doses. Considering multi-agegroup population it advantageous prioritise older groups (upholding thus practice). Finally, investigate whether younger based awareness can be optimal strategy, concluding negative.
