            Pharmacology

            Mechanism of Action

            Attenuated strain of hepatitis A virus (HAV) which stimulates active immunity

            Onset: 4 wk

            Duration: unknown

            These products convey active immunity via stimulation of production of endogenously produced antibodies

            The onset of protection from disease is relatively slow, but duration is long lasting (years)
