World Immunization Week 2022: How Do Vaccines Work?

World Health Organization says vaccines are basically the part of the germ that our body can recognise and develop an immune response. All vaccines being developed provide our immune system a small amount of the germ that we know can cause the disease. So, vaccines basically trains the immune system to fight the particular disease, so that it is completely ready and when it actually sees that particular germ, it protects us from developing any severe disease and fight the infection easily.
