Fig. 6.

Effect of the vaccination policy on the burden COVID-19 for a 20% coverage at time horizon of half year. (A) Vaccination policies’ response regarding constant (${\psi }_V$) and optimal (${\psi }_V+u_V\left(t\right)$) vaccination rates in the burden of COVID-19 quantified in DALYs. (B) Evolution of the vaccination covering according to each policy. (C) Vaccination schedule for each vaccination policy. Blue line corresponds to policies with constant vaccination rate 0.001 239 69. Green line corresponds to optimal vaccination policy. For counterfactual reference (panel A), black line represents the burden of COVID-19 without vaccination. See https://plotly.com/ MAAZ/366/ for plotly visualization and data.
