Immunity develops in………days, after the administration of Japanese encephalitis vaccine:
Formalin-inactivated vaccine purified from mouse brain is given for prophylaxis of Japanese encephalitis. For primary immunization two doses of one ml each should be administered subcutaneously at an interval of seven to fourteen days. (For children under the age of three years 0.5 ml should be given). A booster dose of one ml should be given after a few months in order to develop full protection. Protective immunity develops in about a month's time after the administration of second dose.
