How do medicines help the immune system to carry out its functions?

Medicines can support the immune system by enhancing its ability to recognize and respond to pathogens, such as viruses and bacteria. Immunomodulators can boost immune responses, while vaccines train the immune system to recognize specific threats without causing disease. Additionally, some medications can reduce inflammation or suppress overactive immune responses, helping to maintain balance and prevent tissue damage. Overall, these therapies help optimize the immune system's effectiveness in protecting the body.
