Health
Germany has high food and drinking-water standards, and tap water is generally safe in public systems. Use normal food hygiene, and take extra care with untreated lake/river water or floodwater. Main outdoor risks are ticks in woods/grassland, summer heat waves, UV exposure, and fast-changing mountain weather in the Alps/Black Forest; most itineraries are low altitude, though high Alpine hikes need usual acclimatization caution. Avoid bug bites and check for ticks after hiking.
Vaccinations
Consult a doctor or travel clinic at least a month before travel. CDC advises being up to date on routine vaccines, including MMR, polio, flu, varicella, Tdap/Td and shingles where age-appropriate, plus COVID-19. Hepatitis A is considered for most travelers, especially rural/small-town or street-food plans; hepatitis B is recommended for unvaccinated travelers under 60 and may be considered for older travelers. Because poliovirus has been identified in Germany in the past year, adults previously fully vaccinated may discuss a one-time IPV booster. Tick-borne encephalitis vaccine is recommended/considered for travelers with extensive outdoor tick exposure in endemic areas. Rabies pre-exposure vaccine is usually only for higher animal-exposure risk. Yellow-fever vaccine is not recommended and no certificate is required for Germany.
eSIM / connectivity
eSIM is widely supported in Germany on compatible unlocked phones. Major local networks include Telekom, Vodafone, O2/Telefónica and 1&1; eSIM is available on many postpaid and prepaid products, but prepaid activation may require identity verification and some setup may be easier after arrival. O2 explicitly offers prepaid eSIM activation, while Telekom/Vodafone support eSIM across many tariffs. Travelers can also use reputable Europe/Germany travel eSIM data plans; compare coverage, hotspot rules and whether calls/SMS are included, not just data allowance.
