Question

What do you mean by vaccine ? Who discovered vaccine for the first time?

Answer 1

Vaccines are prepared from dead or weakened microbes. Edward Jenner was the first person to discover small pox vaccine.

• He coined the term vaccination. When the vaccine is injected to the body of a patient, the body produces antibodies to fight against the germs.
• These antibodies remain inside the body and protects from future invasion of the germs.
• Therefore vaccination is otherwise called as immunization.

Examples:

• MMR vaccine for Measles, Mumps, Rubella.
• BCG (Bacille Calmette Guerin) vaccine for Tuberculosis.
