Health
Practical risks vary by route: use normal food-and-water caution, especially outside major hotels; consider bottled/filtered water if unsure. Ticks are important in forests/grassland, with tick-borne encephalitis in endemic areas and Crimean-Congo hemorrhagic fever reported in parts of southern Russia. Mosquito risk is seasonal; CDC does not list malaria prevention for Russia. Plan for heat in summer cities, severe cold in winter, sun/altitude issues in the Caucasus, and changing weather outdoors.
Vaccinations
Consult a doctor or travel clinic at least 4 weeks before travel. Be up to date on routine vaccines, including MMR, polio, tetanus/diphtheria/pertussis, influenza, varicella, shingles when eligible, and COVID-19. CDC recommends hepatitis A for unvaccinated travelers and hepatitis B for many travelers. Depending on itinerary and activities, discuss tick-borne encephalitis, Japanese encephalitis for longer/rural Far East exposure, and rabies for animal or remote/outdoor risk. Yellow fever vaccine is not recommended and not required for entry.
eSIM / connectivity
eSIM is supported by major Russian mobile operators, including MTS, MegaFon, Beeline and t2/Tele2, but availability for visitors can depend on device compatibility, passport registration, operator shop procedures and payment/app access. For reliable arrival connectivity, expect to verify options at official carrier shops or airport counters; physical tourist SIMs and data plans may be easier than remote eSIM activation.
