Heat stability of potency of bacterial vaccines and the titer of tetanus antitoxin of Polish production

: Described the stability of potency vaccines (DTP, BCG) and immunoglobulins (human's and animal's) at storage and experimental temperatures. Thermal degradation rate and design of loss of potency in time have been determined by Arrhenius equation. Our results were similar to WHO data from preparations which have been made in another countries.
