'Vaccines are designed to protect individuals from infectious diseases by building immunity to a specific pathogen. They work by introducing a harmless form of the pathogen into the body, which triggers an immune response. This, in turn, creates memory cells that enable the body to remember and fight the pathogen in the future. There are different types of vaccines, including live attenuated vaccines, inactivated vaccines, subunit vaccines, and mRNA vaccines, each with its own advantages and disadvantages.'
