🇺🇸 Vaccines for USA

Entry requirements & recommendations for travel to USA

No travel-specific vaccines needed for the United States. Routine vaccinations should be current. The US has good healthcare but it is extraordinarily expensive without insurance. Travel insurance with medical cover is essential — a single emergency room visit can run to thousands of dollars, and serious treatment to tens of thousands. Tap water is safe throughout, though quality varies by city and some locals prefer filtered water. The US is large and health conditions vary by region: Lyme disease risk in the northeast, West Nile Virus in various regions, hantavirus in the southwest. None of these are concerns for typical city tourists.
