"Defences against disease-causing germs — pathogens — consist of two systems: innate and adaptive. The innate immune system responds to general threats after detecting molecular patterns characteristic of microbes, such as certain sugars on bacteria, while the adaptive immune system learns to recognize and remember specific pathogens. Together they create immunity — protection from infection." excerpted from https://www.forbes.com/sites/jvchamary/2020/11/29/coronavirus-immune-system/?sh=477395321c69
