Consult with your doctor before your trip to India.  Depending on your health situation, you may need one or more vaccinations.  As per the Center for Disease Control (CDC), the following vaccines may be recommended for your travel to South Asia. Discuss your travel plans and personal health with a health-care provider to determine which vaccines you will need. 

• Hepatitis A or immune globulin (IG). Transmission of hepatitis A virus can occur through direct person-to-person contact; through exposure to contaminated water, ice, or shellfish harvested in contaminated water; or from fruits, vegetables, or other foods that are eaten uncooked and that were contaminated during harvesting or subsequent handling.
• Hepatitis B, especially if you might be exposed to blood or body fluids (for example, health-care workers), have sexual contact with the local population, or be exposed through medical treatment. Hepatitis B vaccine is now recommended for all infants and for children ages 11–12 years who did not receive the series as infants.
• Japanese encephalitis, if you plan to visit rural farming areas and under special circumstances, such as a known outbreak of Japanese encephalitis.
• Malaria: your risk of malaria may be high in these countries, including cities. See your health care provider for a prescription antimalarial drug. For details concerning risk and preventive medications, see Malaria Information for Travelers to South Asia.
• Rabies, if you might have extensive unprotected outdoor exposure in rural areas, such as might occur during camping, hiking, or bicycling, or engaging in certain occupational activities.
• Typhoid. Typhoid fever can be contracted through contaminated drinking water or food, or by eating food or drinking beverages that have been handled by a person who is infected. Large outbreaks are most often related to fecal contamination of water supplies or foods sold by street vendors Vaccination is particularly important because of the presence of S. typhi strains resistant to multiple antibiotics in this region. There have been recent reports of typhoid drug resistance in India and Nepal.
