The timing and scheduling of vaccinations are critical for optimal protection. The CDC immunization schedule outlines specific ages and intervals for each vaccine. For example:
Hepatitis B: Birth, 1-2 months, and 6-18 months. DTaP: 2, 4, 6, and 15-18 months, and 4-6 years. MMR: 12-15 months and 4-6 years.
