In this episode of Nursing Student Deep Dive, we break down one of the most high-yield pharmacology topics you’ll encounter in nursing school: vaccines and immunomodulators. We start by grounding you in the basics of immunity, walking through the innate and adaptive immune systems and how cell-mediated and humoral responses work together to protect the body. From there, we connect those fundamentals directly to how vaccines work, including live-attenuated, inactivated, and mRNA vaccines, with a strong emphasis on nursing responsibilities like screening for contraindications, recognizing expected side effects, and identifying true adverse reactions versus normal immune responses
