It is unlikely that you will encounter unusual health problems in the Netherlands, and if you do, standards of care are world-class. It is still important to have health insurance for your trip.
A few travelling tips:
If you're an EU citizen, a European Health Insurance Card (EHIC), available from health centres or, in the UK, post offices, covers you for most medical care. It will not cover you for non-emergencies or emergency repatriation. Citizens from other countries should find out if there is a reciprocal arrangement for free medical care between their country and the Netherlands. If you do need health insurance, make sure you get a policy that covers you for the worst possible scenario, such as an accident requiring an emergency flight home. Find out in advance if your insurance plan will make payments directly to providers or reimburse you later for overseas health expenditures.
No jabs are necessary for the Netherlands. However, the World Health Organization (WHO) recommends that all travellers should be covered for diphtheria, tetanus, measles, mumps, rubella and polio, regardless of their destination.
Good health care is readily available. For minor self-limiting illnesses an apotheek (pharmacy) can give valuable advice and sell over-the-counter medication. It can also advise when more specialised help is required and point you in the right direction. The standard of dental care is usually good; however, it is sensible to have a dental check-up before a long trip.
