flu

Snot is not pleasant, specially if it runs down your face. But it is also very useful. It helps us to not get sick.

Have you ever had a runny nose?

Vaccines are made from germs that can cause the disease, and their job is to get our body’s natural defences working to protect us against the infection.

A vaccine is a preparation that causes your body to produce antibodies which will make you immune to a disease. Antibodies? Immune?

Snot is a thick, gooey, sticky substance produced in some parts of our body. Poses no risk to your health, but it may be annoying.
