🇺🇸 Vaccines for USA
Entry requirements & recommendations for travel to USA
The USA requires no specific travel vaccines and has world-class healthcare infrastructure, though as with the UK, visitors need comprehensive travel insurance since healthcare costs for non-residents without coverage can be extremely high — this is arguably the single most important practical consideration for visiting the USA, more so than any vaccine question. There's no malaria risk. Lyme disease exists in parts of the northeast and upper midwest for those spending extended time in tick habitats, and West Nile virus occurs at low levels in summer in various states, but neither represents a significant practical risk for typical city or attraction-focused visits. Most visitors travel for a mix of major cities (New York, Los Angeles, etc.), national parks, and theme parks.

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.
