Israel Travel Health Advice
There are no special health precautions required for travel to Israel, but insect protection from August to November is recommended due to the prevalence of the West Nile virus, which is transmitted by mosquitoes. A hepatitis A vaccine is sometimes recommended by doctors, as is a tetanus vaccine and an MMR (measles, mumps, rubella) vaccination for those who haven't already had it.
Medical facilities in Israel are excellent but treatment can be very expensive, so it is essential that travellers take out full travel health insurance. It should be possible to get all necessary medications in the cities but it is always advised that travellers who need certain medications take them along on their travels, along with the prescription and a letter from their doctor.
