The temperature dependence of the effective masses of vector mesons ([rho] and [omega]) and axial-vector mesons ([ital A][sub 1]) are examined with the use of an effective chiral Lagrangian. The effective masses at finite temperature are determined from the pole positions of the propagators and from the inverses of the static screening lengths. The results may be viewed as an extrapolation of known hadronic interactions to temperatures up to a deconfinement/chiral-symmetry-restoring transition or crossover.
