What is the differrnce between Tdap and DTaP?

Tdap and DTaP are both vaccines that protect against tetanus, diphtheria, and pertussis (whooping cough), but they are designed for different age groups. DTaP is given to children under the age of 7, providing a stronger immune response with higher antigen concentrations. In contrast, Tdap is a booster vaccine for adolescents and adults, containing lower doses of the same antigens to reduce the risk of side effects while still providing protection.
