Vaccines

VaccineRecommendationReference
Routine vaccines

Make sure you are up-to-date on all routine vaccines before every trip — per the Swiss BAG schedule. These include:

BAG Impfplan
Chikungunya

Vaccination indicated during chikungunya outbreaks; may also be considered for countries with elevated risk (see EKRM statement).

Dengue

Qdenga® vaccination currently recommended only for travelers with documented prior dengue infection who will be exposed in a region with high dengue transmission.

Hepatitis A

Recommended for all travelers to tropical and subtropical countries. Note for Swiss travelers: Hepatitis A is not part of the routine Swiss BAG childhood schedule, so most adult travelers will need vaccination. Two doses (0 and 6–12 months) provide long-term protection; a single dose is effective for short trips.

CDC Yellow Book
Hepatitis B

Consider per individual risk and stay duration. Routine in Swiss childhood schedule since 1998 — younger travelers usually covered.

CDC Yellow Book
Japanese encephalitis

Recommended for travelers spending >1 month in rural rice-growing areas during transmission season (mainly May–October, varies by region). Highest risk in the Terai (Uttar Pradesh, Bihar) and Northeast states. Not needed for typical urban or short-stay tourist itineraries.

Rabies

Strongly consider pre-exposure vaccination for: long stays; trips with high individual risk regardless of duration (cycling/motorbike trips, hiking in remote areas, infants and children, those working with animals, cavers — bats!). India accounts for roughly one-third of global rabies deaths, and post-exposure rabies immunoglobulin can be hard to obtain locally.

CDC Yellow Book
Typhoid

Recommended for all travelers with stays longer than 1 week. India has among the highest typhoid incidence globally, and risk extends to major cities and high-end accommodation, not just rural areas.

CDC Yellow Book

Disease-specific guidance

Malaria

Moderate

Risk is altitude- and region-dependent. High and moderate risk concentrated in eastern and northeastern states <2500m; the rest of the country including major cities is low risk (mosquito protection only). No risk above 2500m in Himachal Pradesh, Jammu, Kashmir, and Sikkim. Discuss chemoprophylaxis with a travel medicine specialist based on specific destinations — many tourist routes are low-risk.

High risk
<2500m in parts of east and northeast
Moderate risk
<2500m in further parts of east and northeast
Low risk
<2500m elsewhere — Delhi, Mumbai, Kolkata, Rajasthan, Andaman/Nicobar Islands
No risk
>2500m in Himachal Pradesh, Jammu, Kashmir, Sikkim
Species
P. vivax (60–65%), P. falciparum (35–40%)
Resistance
Chloroquine-resistant — use AP, doxycycline, or mefloquine
Malaria risk areas in India (CDC).

Yellow fever

None

No yellow fever risk in country, but India enforces a strict entry rule: travelers arriving within 6 days from a yellow-fever-endemic country (or in transit through one) without a valid YF vaccination certificate face 6 days of quarantine. Quarantine facilities exist only at Delhi (DEL), Chennai (MAA), and Mumbai (BOM) airports — at other airports, travelers are deported. India only accepts single-page YF certificates in Hindi, English, and French. Direct flights from Switzerland are not affected.

Dengue

High

Endemic and rising. Year-round risk in southern India; northern India sees monsoon-driven peaks (June–October). Major urban outbreaks have become common, including Delhi, Mumbai, Bangalore, Kolkata. Qdenga® vaccine currently recommended only for travelers with prior documented dengue infection who will be in high-transmission regions; daytime mosquito-bite prevention is the main protection for everyone else.

Aedes aegypti — bites during daytime

Chikungunya

High

Recurrent outbreaks across India, distribution similar to dengue (urban and peri-urban). Same daytime Aedes mosquito vector means dengue precautions also protect against chikungunya. Vaccination considered in outbreak settings or for elevated individual risk (see EKRM statement).

General prevention

Food & water

Strict food and water precautions are essential. Use bottled or filtered water, avoid ice, raw produce, and street food in all settings — including major cities and high-end accommodations. Foodborne illness affects most travelers regardless of accommodation level.

Mosquito protection

Year-round dengue and chikungunya risk requires daytime mosquito protection (DEET or picaridin repellent, long sleeves). For rural travel and stays >1 month in transmission areas, also protect at dawn/dusk for malaria and Japanese encephalitis. Sleep under treated bed nets in lower-quality accommodations.
