The DTP vaccine—also known as Td/IPV or the 3‑in‑1 teenage booster—helps maintain protection against tetanus, diphtheria and polio. This booster safely reinforces early childhood vaccinations, helping guard against these serious infections.
How is it given
The vaccine is administered as a single injection into the upper arm.
Who should have it
All children in year 9 (approximate ages 13 to 14) with catch-up sessions in Years 9–10.
Why it matters
Protection from childhood (pre-school) vaccines can lessen over time. The teenage booster reinforces immunity before independence and travel become more common — ensuring continued protection against tetanus, diphtheria, and polio.
Side effects
Side effects are usually mild and short‑lived.
They can include:
- redness, swelling or tenderness at the injection site
- slight fever, mild headache or tiredness
- occasionally, nausea or aching muscles
- a small, painless lump may form which then fades within a few weeks
