Prior to being able to enroll in daycare you will need to show proof that your child has been vaccinated against certain diseases before he/she can attend daycare. The mandatory vaccines are those against poliomyelitis, diphtheria, pertussis, meningitis with haemophilus influenzae b, measles, rubella, mumps. These vaccines are mandatory because of the risk that an unvaccinated child would cause to the community of children.
