Acquired immunity refers to the immune response that develops after exposure to a specific pathogen or through vaccination. It involves the production of antibodies and memory cells that can recognize and fight off the pathogen upon future exposure, providing a faster and stronger defense against the same pathogen. This type of immunity is more specific and targeted compared to innate immunity.
There is innate immunity (that you are born with) and acquired immunity. Acquired immunity you get when you are vaccinated or you get the disease and fight it off. The best example is that of what we call common colds. There are about 100 different viruses that cause them. This is one reason that babies and young children seem to be always be coming down with one or getting over one.
