India Government, CDC and the US Travel Department have a recommended list of vaccinations in preparation for travel to India. Entry into the country does not require any documentation of vaccinations with one exception. Yellow Fever vaccination is required for all travelers arriving from or transiting through a yellow-fever-infected area in Africa or the Americas (Not recommended otherwise). You can find a complete list of the recommended vaccinations here.
I’ve traveled to India 6 times since 2005 with no vaccinations other than those administered as a child here in the USA. The exception, a tetanus shot in Amritsar after an unfortunate rickshaw accident. Based on reading and discussion with various medical professionals in the past, my opinions on vaccinations were not positive. Upon reviewing this information with my travel partner (A nurse), and the urging of my partner (a Physician Assistant), I reluctantly agreed to seek the Hep A & B vaccines.
Vaccinations can be obtained at most clinics and hospitals depending on your location. Call ahead for pricing to avoid any surprises. Many insurance plans do not cover vaccinations for travel related reasons. My local clinic quoted $827.00 for Hep A, B, Typhoid and a Polio booster. However, after a little research online, for $155, I can receive the full course of Hep A & B at my County Health Department.
Low cost vaccinations can also be obtained once in India however, most medical professionals will advise to begin any courses prior to arriving in the country. Check with local hospitals/clinics for rates.
