adaptive immune system

The adaptive immune system is the part of your body's defense that learns to recognize and respond specifically to different pathogens, like viruses and bacteria. It develops over time, creating tailored responses and "memory" of past infections, which helps it respond more quickly if the same pathogen attacks again. This system involves specialized cells called lymphocytes (B cells and T cells) that identify and target specific invaders. Vaccinations work by training your adaptive immunity to recognize a pathogen without causing illness, providing long-lasting protection against future infections.
