The Amsterdam Public Health Service (GGD) says that three quarters of the pilgrims to Mecca take unnecessary health risks.
Their travelers' department advises a thousand pilgrims every year. Just a quarter get the non-compulsory, but strongly recommended, vaccinations. Saudi-Arabia requires every pilgrim to be vaccinated for meningitis.
The GGD also advises to get vaccination against other infectious diseases: tetanus, polio, hepatitis A and typhoid fever.
