The first immunizations for tetanus, diphtheria and pertussis (the DTaP shots) start when kids are only 2 months old (definitely no earlier than 6 weeks). Adolescents get a booster Tdap shot at around 11-12 years (if they miss it, it's OK for them to get Tdap between 13-18 years). Adults should get a Tdap shot for one of their tetanus boosters. The others will all be Td shots. Remember, you need a tetanus booster every 10 years. If you are over 65 years old you might not need the Tdap shot, but you can still get one.
