The idea of herd immunity is based on the thought that, as a community, we can protect our most vulnerable people. Newborns and people with compromised immune systems are one example. They can’t receive some vaccines, or they can’t develop immunity to diseases. In the case of newborns, they receive vaccines in a scheduled series, and are susceptibl...
Vaccines can help create herd immunity by allowing our bodies to protect us from a disease without actually getting sick. Each specific vaccine trains the body’s immune system to detect and fight the targeted-disease. Vaccinating healthy people and reducing their ability to spread diseases protects people who can’t be vaccinated. The eradication of...
