No mandatory vaccinations are required in order to enter Indian territory for any foreign nationals including riders from the United States, Australia, and Europe. However, this regulation does not apply to those traveling from yellow fever areas, including Africa, New Guinea, and Latin America. For this reason, travelers who have previously been in these areas must present their yellow fever vaccination certificate. In addition, exercise caution while traveling in crowded areas or when deviating from the defined itinerary. As a preventive measure, it is best to be vaccinated against Hepatitis A, Hepatitis B, Typhoid and Tuberculosis.
