Based on the explanation above, it should be clear that antibiotics are used specifically to target and eliminate infections caused by susceptible pathogens. What about immunity? Our body's immunity is its ability to defend against and fight off external pathogens. This immunity is a manifestation of various factors such as genetic predisposition, personal constitution, mental state, gut microbiome, age, and more. Antibiotics do not enhance the body's immunity. In fact, misuse of antibiotics can harm the body's immune system, leading to significant issues. Misuse, like the idea of taking amoxicillin for a year to boost immunity, is a classic example.
