Adaptive immunity is really important for fighting off viral infections. It helps the body recognize specific germs and respond in the best way. Here’s how it works:
Specificity: Adaptive immunity uses T cells and B cells. These cells can spot unique parts of a virus, called antigens. For example, when the flu virus gets into your body, special B cells make antibodies. These antibodies attach to the virus and keep it from getting into your cells.
Memory Formation: After your body fights an infection, some B and T cells stick around. These memory cells help the body react quicker and stronger if it encounters the same virus again. This is why vaccines work so well; they help build this memory without making you sick.
Cytotoxicity: Cytotoxic T cells are like little warriors. They can kill cells that are infected by a virus, stopping the virus from making copies of itself and spreading.
Overall, by giving targeted and long-lasting protection, adaptive immunity is key to keeping viral infections under control.
