What should you know about DPT polio vaccine age?

DPT refers to protection against diphtheria, pertussis and tetanus. Polio vaccination protects against poliomyelitis, an infection that can affect the nervous system. The doses are arranged across infancy and childhood so protection can build and be maintained. The exact timing can differ by national programme, previous vaccines, age, and health history.

A sore arm, mild fever, tiredness or irritability can occur after vaccination and usually settle with simple care. These reactions are different from the diseases the vaccines prevent.

Take the child’s vaccination record to a paediatric or primary-care appointment. The clinician can check which DPT and polio doses were given, identify any missed dose, and make a catch-up plan. A delayed dose does not usually mean the series must start again; the appropriate next dose depends on the record and the child’s age.

Tell the vaccinator about a previous severe reaction, a significant immune problem, or an acute illness. Keep the record updated after every visit and follow the local schedule described in Childhood Immunisation.

Seek urgent help for trouble breathing, swelling of the face or throat, collapse, or a child who is unusually difficult to wake after vaccination. Contact the clinic promptly for a fever or reaction that is worsening, persistent, or causing concern. Do not delay emergency care while looking for the vaccine record.

Which DPT and polio doses are recorded, and which dose is due next? Does the child need a catch-up schedule? What reactions should we expect, and which symptoms need urgent attention? Are there health conditions or medicines that change the vaccination plan?
