Vaccines & Immunisation

• Inside a vaccine are the pathogens that we want to be immune to, but they've been weakened, so they can't cause disease, but our body still responds by developing immunity.
• Vaccines can work against bacteria and viruses.
• Vaccines protect us from diseases, control common diseases from being spread and prevent big outbreaks (epidemics) which saves lives.
• Vaccines have large effects due herd immunity, as loads of people can't get ill because they are immune to the disease.
• Vaccines don't always work
• Some people have bad reactions to vaccines (rarely causing fevers and seizures)
