How long does the dtp vaccien last for?

The DTP vaccine, which protects against diphtheria, tetanus, and pertussis, typically provides long-lasting immunity, though the duration can vary. Primary vaccination is usually given in childhood, followed by booster doses. Immunity to diphtheria and tetanus can last for about 10 years, while protection against pertussis may diminish more quickly. Therefore, it's recommended to receive a Tdap booster every 10 years for continued protection.
