Diphtheria is preventable through active immunization. Effective control of the disease can be ensured through high population immunity by providing three doses of diphtheria-containing vaccine to all children below one year of age. The first dose of diphtheria-containing vaccine is given to children at age 6 weeks and then at least four weeks apart for the second and third dose of the vaccine. 

Diphtheria vaccine is a toxoid that is available in different combinations with other vaccines. Diphtheria vaccine is safe, effective and well tolerated.
