No vaccination is required to travel to India (unless you have previously traveled to countries at risk). However, we suggest that you keep your vaccines up-to-date:
DTP (Diphtheria-Tetanus-Poliomyelitis), typhoid fever, and viral hepatitis A and B.
If you plan to stay in India for an extended period of time, rabies vaccination may be recommended.
Malaria treatment is not mandatory in India as the risk is relatively low (especially in large cities). It is not, however, nil. In any case, you can consult your doctor or a specialized center before traveling to India if you would like more specific information about this.
