Vaccines are biological materials designed to generate active immunity against a particular disease. Vaccines mimic the infectious bacteria or viruses responsible for a disease. Inoculation of vaccines stimulates the immune system in the human body to build a defence against the infectious micro-organism (antigens) without causing the disease.
There are different kinds of vaccines available currently out of which few contain weakened versions of a bacteria or virus; others contain a specific part of the bacteria or virus, while a few vaccines contain only the genetic material for a specific protein (mRNA vaccines). In mRNA vaccines, the genetic material (a specific protein) asks the body to produce the required protein by itself stimulating the body to generate an immune response against the micro-organism...read more
