Answer:
Vaccine was discovered for the first time by the British doctor Edward Jenner. Two diseases which can be prevented by using vaccines are tuberculosis and hepatitis.
the immune system protects our body from disease caused by various harmful microorganisms and other foreign bodies. the immune system is responsible for download regulating immune responses against external harmful triggers such as food or against the body's own tissue.
There are many diseases that cannot be cured. No medicines are there yet to treat them like AIDS or cancer. So it is better not to get the disease rather than to cure it. If we can prevent the disease to occur then no medicines are required. More over the medicines have several side effects that may destroy some other system while curing a disease. Thus it is better to prevent the disease to occur than to cure it by applying medicines. Hence prevention is better than cure.
some children fall ill more frequently than other living in the same area due to weak or slow immunity.
virus are simple cells but they use the host cells for carrying out all the functions and activities required for them to grow. so antibiotics are useless against viral infections.
