Prevention is better than cure. Vaccines are one category of medicine. The purpose of vaccines is to mitigate the spread of infectious diseases. They work by boostingthe body's immune response to specific infections that can cause illness. This is an important weapon in fighting against infections that cause disease. Since they have been around for a while, vaccines have aided humanity in preventing many infectious diseases. Vaccines come in many different types, including mRNA vaccines, subunit, recombinant, or conjugate vaccines, live attenuated vaccines, and inactivated or dead vaccines. Many infectious illnesses, including smallpox, polio, and measles, have been successfully stopped from spreading thanks to vaccinations, which have also saved countless lives. Vaccines work like drugs in such a way that they trigger an immune response against a specific organism that causes a particular disease. This response results in the development of memory cells that can recognize and fight pathogens if they reoccur, thus providing immunity to disease. Vaccines have prevented the spread of many infectious diseases and saved countless lives.
