The first line of defense when it comes to fighting infections is Innate Immunity. This type of immunity is always present in the body and is non-specific, meaning it doesn't target specific types of pathogens. It includes physical barriers like skin and mucous membranes, as well as cells and chemicals that respond quickly to infections. On the other hand, Adaptive Immunity is a specific immune response that occurs after exposure to an antigen either from a pathogen or a vaccination.
