In this paper we investigate the vacuum polarization effects associated withquantum fermionic charged fields in a generalized $(d+1)-$dimensional cosmicstring space-times considering the presence of a magnetic flux along thestring. In order to develop this analysis we calculate a general expression forthe respective Green function, valid for several different values of $d$, whichis expressed in terms of a bispinor associated with the square of the Diracoperator. Adopting this result, we explicitly calculate the renormalized vacuumexpectation values of the energy-momentum tensors, $<T^A_B>_{Ren.}$, associatedwith massless fields. Moreover, for specific values of the parameters whichcodify the cosmic string and the fractional part of the ratio of the magneticflux by the quantum one, we were able to present in closed forms the bispinorand the respective Green function for massive fields.
