South Asia vaccine checklist
Japanese encephalitis and typhoid in South Asia
Typhoid and Japanese encephalitis are the two most frequently recommended vaccines for travel to South Asia. Both of these vaccines are safe and effective. Both of the diseases they protect against are deadly or disabling.
Typhoid vaccine: This vaccine provides protection from typhoid fever which is mainly spread through contaminated water. You can choose from an oral vaccine or an injection. Typhoid can be treated with antibiotics but extremely drug-resistant typhoid has become prevalent in Pakistan and other areas.
Japanese encephalitis vaccine: This vaccine protects against Japanese encephalitis virus which is spread by mosquitoes.
You may need malaria pills too
There is currently no vaccine in the U.S. for malaria but there are drugs you can take to help prevent malaria. Talk to a travel health specialist about your options. Whether you need to take malaria pills really depends on where you go and what you're doing while there.
