Are there any side effects?

Vaccinations can cause a reaction in your body. This is usually small things like redness, swollen skin and a numb pain around where you were injected.

People can also have a headache, feel hot or have aches in their arms and legs and might feel tired. This might last for two or three days after the injection. It shows the vaccine is working and the body is fighting back and making the antibodies it needs. More serious side effects are very rare.
