Have you heard about Vaccination? No I don't know anything about it. Nothing at all? Maybe in your school or at home? What is a vaccine? Haven't heard anything? Look, in our childhood the vaccines were injected in the arms Interviewer: Right. That would end all diseases. In our times, there were no doctors or injections.
Interviewer: Right. In our times, there was some sort of a nail, which pierced the arm and was twisted. The wound would heal in a day or two. The mark of the wound is still there. Vaccine? ('Teeka' in Hindi) *thinking* One is the mark worn usually on the forehead (in Hindu rituals) Second, injections are also called 'Teeka' in Hindi Never heard of it. Vaccination is given to new born babies. Vaccination? The one that is given to the newly born? 'Teeka' is used for bodybuilding.
Interviewer: Has anyone in your family been vaccinated? Interviewer: No? INTRO Aaj Ka Prashn (in English) INTRO Aaj Ka Prashn (in Hindi) So we asked some people on what they know about vaccination And in these videos you must have seen that many people have heard about vaccination Have even been vaccinated themselves But they are unaware as to Why should we get vaccines in the first place? So if even you are confused about
Why these vaccines are administered? or How vaccination works? Let us, through this video, know the science behind vaccines. INTRO What is Vaccination? So, in the current day and age, have you seen anyone diseased with Smallpox or Polio. No right? But, in the past the situation was quite different. In olden times, these endemics had costed a lot of lives. So, if I take the example of fighting Polio.
You'd probably recall the "Pulse Polio" campaign and its slogan "Two drops of life!" In 2009, about 741 cases of Polio were reported in India. But in 2011, thanks to the immunisation campaign, India was declared polio-free. These days, children are administered with a lot of different vaccines, apart from smallpox and polio. Like for Hepatitis A, Hepatitis B, Tuberculosis, Tetanus. And if you'd like to know the Immunization Schedule for children in India, you can click on the link in the description.
When a child is born, their immunity lacks strength. Therefore, a lot of vaccines are administered early on. Poor babies. At this point, you might think - What is it in these vaccines that we are spared from acquiring these diseases. So, to know as to how these vaccines work, let us try to better understand our body. You probably know that our body has the ability to fight diseases within. We also call this 'Immunity'. This means that, if a pathogen enters our body,
The white blood cells in our body fight the pathogen and save us from the disease. Many times, our white blood cells get rid of these foreign invaders, without us having any clue about it. But, if our body (immunity) is weak and our WBCs are unable to fight the pathogens, or if the pathogen is quite strong, we fall sick. One important thing to note here is that whenever our army of White Blood Cells
Fight the Pathogens, and successfully defeat them, some cells are left behind which are called Memory Cells. These Memory Cells remember the same pathogen for faster antibody production in future infections.
