Who should have the 3-in-1 booster?

The 3-in-1 teenage booster is free on the NHS for all young people aged 14, as part of the national immunisation programme.

It's routinely given at secondary school (in school year 9) at the same time as the MenACWY vaccine.

Schools will send a letter to parents shortly before the vaccinations are planned to ask for their or their child's consent.

Children who are home educated will also be offered the vaccine, provided they're in an eligible school age group.

How safe is the 3-in-1 booster vaccine?

The 3-in-1 teenage booster is a very safe vaccine.

As with all vaccines, some people may have minor side effects, such as swelling, redness or tenderness where the injection is given.

Sometimes a small painless lump develops, but it usually disappears in a few weeks.

The brand name of the 3-in-1 teenage booster vaccine given in the UK is Revaxis.
