Answers
Answer:
From birth, we are constantly exposed to many different viruses, bacteria and other microbes. Most are not harmful, many are beneficial but some can cause disease.The body's immune system helps protect us against infections. When we are exposed to infection, the immune system triggers a series of responses to neutralise the microbes and limit their harmful effects. Exposure to an infectious disease often gives lifelong protection (immunity) so we do not contract the same disease again. Our immune system “remembers” the microbe.
A vaccine activates our immune system without making us sick. Many dangerous infectious diseases can be prevented in this simple and effective way.During vaccination, the body is exposed to either a weakened microbe (bacteria or virus), fragments of a microbe, or something that resembles the microbe. When the active substances in the vaccine meet the body's immune system, immune cells and antibodies are produced that will recognise the "real" microbe. When the vaccinated person encounters this microbe, the immune system will provide a faster and better immune response that can prevent disease. This is artificially acquired active immunity. So vaccination is important because it boosts our immunity power and protect us from viruses.
the vaccine is very important because it can save hundred of lives in all over the world there are some sideffects of the vaccine too but people have to vaccinate their selves to stay alive many and now the vaccine is invented people get vaccined and the cases in many countries like pakistan china etc are decreasing tgats how vaccines for corona plays a very important role these days
