Which vaccine has the largest number of routine doses in some countries when combined with other childhood shots?
Quick Answer
Combination childhood vaccines can include multiple doses of DTaP-containing schedules, especially in infancy and early childhood. Exact schedules vary by country, but the diphtheria-tetanus-pertussis series is among the most common.
The Full Story
The diphtheria-tetanus-pertussis, or DTP/DTaP, vaccine series is one of the most commonly repeated vaccine schedules in childhood. Depending on the country, children may receive several primary doses in infancy plus boosters later in childhood or adolescence. When combined with polio, hepatitis B, Hib, or other antigens in combination vaccines, the early-life schedule can include many injections overall. The goal is long-term protection during the years of highest vulnerability.
