On the impact of vaccination campaigns and social distancing in the control of the novel coronavirus outbreaks

Abstract

The continuous spread of "SARS-COV-2" around the globe, push the governments to start vaccination campaigns by approving several vaccines under the emergency procedure. However, the shortage of vaccines supplies slowed down the vaccination campaigns in most countries. In this paper we performed a 'SELIAAvHRD’ model containing nine stages (Susceptible, Exposed, Latent, Symptomatic Infected, Asymptomatic Infected, Asymptomatic Vaccinated, Hospitalized, Recovered and Dead) for analyzing and modelling the effect of social distancing measures and vaccination campaigns. The simulation using the proposed model in different scenarios, shows the importance of respecting the social distancing measure to cover the shortage of vaccine supplies and avert deaths from "SARS-COV-2" across the world.
