Covid-19 and Vaccines Against it

Abstract

With the advent of the Corona virus and its spread throughout the world, the whole world was affected by this disease. In the early year’s advent of the disease, there was no way to cure it, and only by following health protocols could we prevent it. The disease has killed many people around the world. This virus has many effects on the body and mostly has a destructive effect on the lungs. There is a lot of evidence that the effects of this virus remain in the body for a long time and sometimes it causes stroke and heart attack in the elderly with underlying diseases. Pharmaceutical companies around the world began making vaccines against the disease, and many of them were marketed after approval by the Food and Drug Administration. Many of these vaccines have been tested in human samples and their efficacy has been confirmed. The efficacy of these vaccines has sometimes been confirmed to be up to 95%. But what is certain is that not all vaccines are 100% preventable and there is a possibility of recurrence of Covid-19. But research shows that people who get vaccinated and get Covid-19 have a better chance of surviving and have fewer side effects. In the main text, we have listed and described a number of used vaccines with all their characteristics.
