Alfa Chemistry - Vaccine Stabilizers

Vaccine Stabilizers: Successful vaccine stabilization strategies include both empirical efforts to screen and identify appropriate stabilizers and environmental conditions and more rational approaches toward developing an understanding of the causes and mechanisms of vaccine inactivation. Among these, determining the appropriate stabilizer is a critical means of maintaining vaccine potency and efficiency. Such stabilizers stop chemical reactions from occurring in the vaccine and prevent the components from separating from each other or sticking to the vaccine vial during transportation and storage. Over longer time scales of storage, combinations of stabilizers preserved the most vaccine activity.
