The DTaP vaccine is typically given in a series of five doses. The recommended schedule is at 2 months, 4 months, 6 months, 15-18 months, and 4-6 years of age. Boosters are recommended during adolescence and adulthood to maintain immunity, often combined with other vaccines like the Tdap (tetanus, diphtheria, and acellular pertussis) booster.
