Definition
An immune reaction is a specific event or process within the broader immune response, like a battle in a war 💥. It's a particular way the immune system combats a threat, and it can range from mild to severe. Think of it as the immune system taking action—recruiting cells, producing antibodies, or causing inflammation. It's more localized and focused than the overall response. While "immune response" is the whole strategy, "immune reaction" is a specific tactic. 🎯
