Counter plot of the accumulative cases for model (1) as a function of the transmission effective contact rate and the vaccination coverage in (A); as a function of the quarantine rate and vaccination coverage in (B); and as a function of the vaccine efficacy rate and vaccination coverage in (C). We also plot the accumulative cases as a function of the vaccination coverage, with different transmission efficient contacts (D); quarantine rate (E) and vaccine efficacy. The baseline values are fixed as: q = 0.3, β = 1, βv = 1.8, v = 0.5, η = 0.6, and the other parameter values are given in Table 1
