6 questions you might have about immunisation injections

1. What does a vaccine contain?

A vaccine contains a tiny part of the bacterium or virus that causes a disease, or tiny amounts of the chemicals the bacterium produces.

Vaccines work by causing the body’s immune system to make antibodies (substances to fight infections and diseases). So, if you come into contact with the infection in the future, the antibodies will recognise it and protect you.

2. How big is the needle used to give the injection?

Don’t worry, the needle is small; the same size as the needle used to give vaccinations to babies.

3. How long do injections take and where on my body will I be injected?

All injections are given in the top of your arm; but the process is quick. Remember, you’ll be protected against some really nasty diseases.

4. Will having my period mean I can't have the vaccination?

It’s OK to have immunisations whilst you’re on your period.

5. What will happen if I miss the vaccination in school?

If you miss your immunisation, don’t worry as the healthcare team run ‘mop-up’ sessions for those who they missed the first time they were in school.

6. What if I've missed any of the vaccinations I'm supposed to have had when I was younger?

You can check which vaccinations you have had when you were little by looking at your child health record or red book.

You can also ask your doctor to checks your record to make sure you’re fully protected.
