<p>Similarly to the side effects of other vaccines, some people may experience slight flu-like symptoms or minor irritations/irregularities in their body.</p><p><br></p><p>Although this does not happen to every person, or with every vaccine, it usually is not something to be concerned about. Usually, this is merely a sign that your body is learning how to combat Covid-19, and your immune system is working hard. </p><p><br></p><p>Maybe an analogy could be: after exercising in the gym the body may get sore, but this soreness is not bad; it is simply your body recovering and re-building muscles. Likewise, your immune system is "going to the gym" to combat Covid-19, so it is experiencing some stress temporarily. However, it will bounce back stronger than before.</p><p><br></p><p>Hope your symptoms are manageable! Remember to keep hydrated, and to take it easy on yourself for a bit. </p>

<p>When you get infected, your body makes antibodies to fight against the virus and also some cells called memory cells. They remember how to defeat the virus and are saved in your body. So if you get infected again with th same disease, this time it won't affect you because of the memory cells already present in your body. Vaccines are basically pre-made memory cells transferred to your body, you get the most minor version of that virus, generate memory cells and then get immune to that diseasr</p>

<p>Vaccines are actually chemical compositions of dead disease cells which are injected into the body.</p><p>When they are injected into the body,they stimulate the production of antibodies which offer resistance against diseases.</p><p>Thus,when the stronger form of the disease gets into the body's system,these antibodies provide immunity to such a disease.</p>
