vaccinations

Who and when discovered vaccines

Edward Genner in 1796

What pathogens are vaccines uses to prevent?

Mostly viruses

Antigen=

A specific site on the pathogen

Antibodies=

What your body makes to attach to the antigens, disabling the pathogen

Creating antibodies takes time because:

Your body has to match the correct antibody to the correct antigen - like a lock and key

Sights an antibody is working:

• Coughing

• Sneezing

• Fever

Adaptive immunity:

Cells create memories of what invaders look like and how to fight them

Vaccines=

Preparing your body to fight off diseases before you get infected

Live attenuated vacccine:

Made up of a weaker or inactive version of the pathogen itself

Inactive vaccine:

Made up of a version of the pathogen that has been killed

Why do we use vaccines?

• Low risk

• Nuilds up immunity and memory cells

Vaccination side effects:

Symptoms of the actual illness

Subunit vaccine=

Contains only the antigen from the pathogen

Vaccines lead to

Gained immunity

Immunity=

When your body destroys the pathogen before it makes you ill or “symptomatic”
