What are communicable diseases? How do they spread?​

Answer 1

Answer:

Ans _1) A vaccine is a type of medicine that trains the body’s immune system so that it can fight a disease it has not come into contact with before. Vaccines are designed to prevent disease, rather than treat a disease once you have caught it.

To understand how vaccines work, it helps to look first at how the immune system works, because vaccines harness the natural activity of your immune system. This short animation explains how vaccines enable the body to make the right sort of antibodies to fight a particular disease

Ans -2) A communicable disease is one that is spread from one person to another through a variety of ways that include: contact with blood and bodily fluids; breathing in an airborne virus; or by being bitten by an insect.
