How do I know when to take my baby in for vaccinations?

For infants most vaccinations are given on a 2, 4, 6, 12 and 18 months old schedule. Doses cannot be given too close together or immunity doesn’t have time to build up. On the other hand, you don’t want to delay your child’s vaccinations and get behind schedule because during this time, your child remains unprotected against these serious diseases.
