Abstract
Embodiments herein relate to compositions and methods for stabilizing live alphaviruses. Other embodiments relate to compositions and methods for reducing degradation of live, attenuated alphaviruses. Certain embodiments relate to providing a stabilizing composition while reducing immune reaction in a subject to excipients that stabilize the live alphaviruses by providing improved formulations. Yet other embodiments relate to uses of compositions disclosed herein in kits for portable applications and methods wherein the compositions reduce degradation of the live alphaviruses.
