Td / Tdap Vaccine (Tetanus-Diphtheria-Pertussis)

Tdap is a booster vaccine that reinforces protection against Tetanus, Diphtheria, and Pertussis (whooping cough) in adolescents and adults whose childhood immunity has waned. Pertussis immunity typically wanes 4-12 years after the last childhood dose. A single Tdap replaces one Td (tetanus-diphtheria) booster.

The Td / Tdap Vaccine (Tetanus-Diphtheria-Pertussis) is recommended for 10-12 years; then every 10 years. It falls under the Adolescent vaccine category. Consult your doctor to confirm if this vaccine is right for you based on your health history and existing immunity.

The Td / Tdap Vaccine (Tetanus-Diphtheria-Pertussis) has an efficacy of 95%+ against tetanus and diphtheria; 71-89% against pertussis (wanes over 4-12 years). This means it provides significant protection against Tetanus (Lockjaw) and Diphtheria. Efficacy may vary based on age, health status, and the specific strain encountered.

Common side effects include: Pain; redness; swelling at injection site (very common); mild fever. These are typically mild and resolve within 1–3 days. Serious allergic reactions are rare — if you experience difficulty breathing, hives, or rapid heartbeat after vaccination, seek emergency care immediately.

The Td / Tdap Vaccine (Tetanus-Diphtheria-Pertussis) should be avoided by: Encephalopathy within 7 days of prior pertussis-containing vaccine; history of Arthus-type hypersensitivity after prior tetanus/diphtheria toxoid dose.. Always inform your healthcare provider of your full medical history before vaccination.
