In this paper, a fractional-order two-strain SVIR model is proposed. Specifically, the model incorporates vaccine protection that follows a power-law tail distribution and where the vaccine affects the two-strain differently. And the fractional-order derivative form is given by derivation because its memory properties can better characterize the effect of vaccine protection. Meanwhile, we derive an explicit expression for the basic reproduction number of the two-strain and clarify its crucial role in governing the dynamics of the system. The stability results for the fractional-order model are given with the help of Routh–Hurwitz and Lyapunov methods.

In particular, (2+1)-dimensional MFBKKS is reduced to (1+1)-dimensional mixed fractional system using Erdélyi–Kober fractional differential operator. Further, the power series solution of MFBKKS is constructed via power series method. By applying invariant subspace method, we obtain more exact solutions of MFBKKS.
