Write down a short notes on Immunization or Vaccination.
✓

Answer

Vaccination or Immunization work by stimulating the immune system, the natural disease fighting system of the body. The healthy immune system is able to recognize invading bacteria and viruses and produce substances (antibodies) to destroy or disable them. When you get vaccinated, you help protect others as well. Vaccines are very safe. It is much safer to get the vaccine than an infectious disease.
