RESUMEN
This is the first time in Burma that tetanus toxoids (purified and adsorbed) have been tested in over 250 non-immune adult volunteers and studied for a period of nearly five years. The safety and efficacy of these toxoids have been assessed by immunological, statistical and clinical methods. Both toxoids were found to be safe. The adsorbed toxoid was far superior to the fluid toxoid as an immunizing agent and optimum immunization regimens are proposed and presented.

This is the first time in Burma where personnel at risk against rabies have been pre-immunized and the effectiveness of such a procedure has been studied for nearly two years. The first batch of lyophilized, Semple-type, beta propiolactone inactivated anti rabies vaccine produced by the Burma Pharmaceutical Industry (B.P.I.) was used to immunize 55 B.P.I. workers previously unexposed to rabies and with no history of rabies vaccination. Three doses of 0.25 ml of the vaccine were given intradermally at one week intervals. Booster doses were given on the 98th, 392nd and 592nd day after the first dose. Blood samples were taken and serum neutralization tests were performed at varying time intervals after basic immunization and booster doses. Satisfactory antibody responses were obtained. The course of immunological response is presented and discussed.
