- Student, today we will be learning about vaccines from Dr. Coulson.
- GOOD MORNING DR. COULSON!!
- Good Morning Dears, I am Dr. Coulson, Today I will explain you how the vaccines are made and how they work in our bodies.
- So we will begin from the basis, Vaccines provide immunity from infectious diseases like tetanus, diphtheria, whooping cough, measles, polio, etc, Our body has an immune system which fights microbial infection. When this system first sees an infectious microbe, it kills the microbe and remembers it.
- Vaccines are made up of whole bacteria or virus, or parts of them, often a protein or sugar. These active components of the vaccine, called antigens, are what trigger an immune response when in the body.
- Inoculation originated in India or China some time before 200 BC. The concept of immunization, or how to artificially induce the body to resist infection, received a big boost in 1796, when physician Edward Jenner inoculated a young boy in England and successfully prevented him from getting smallpox.
- That's the end of the session childern, I hope you learned something new today and I wish I get a chance to see you all again. GOOD BYE DEARS!!
- GOOD BYE DR. COULSON!!
- Thank You Sir, for such a wonderful session.
