Herd immunity, infectious disease
IntroductionHave you ever wondered why you need to get a flu shot regularly? The vaccine protects you from getting sick with the flu, which is an infectious disease. Such diseases, like the flu or COVID-19, can easily spread through a population and cause a pandemic by making many people sick. Measures such as social distancing can reduce the risk of catching the disease, but real protection only comes from gaining immunity against the disease. This is the reason for vaccinations—to make someone immune to a specific disease. In this activity, you will find out how immunizations can limit the spread of an infectious disease up to a point where the whole population is protected through herd immunity.
