Remembering Infection

The first time you come into contact with a disease, your body has to work out the best way to fight it.

antibodies are required and is then able to effectively attack the disease.

What are vaccines for?

A vaccination is a medicine which boosts a persons immunity to a disease.

Vaccinations

a sore arm or low-grade fever) and go away within a few days.
