It's really important to stay up to date! This is because immunizations help protect people from diseases that may not be easily treatable or that could lead to serious complications. Although children's immune systems are strong, they're not necessarily strong enough to prevent and protect against certain diseases, so some immunizations are necessary. Older adults are especially vulnerable to disease since they have weaker immune systems, so older adults need some immunizations too. There are also people with impaired immune systems that make them more vulnerable to disease, and these people rely on others to get immunized to help prevent the spread of disease. When you get immunized, you protect yourself and others from the spread of disease, and when a community of people gets immunized, they protect everyone in the community. If a community is exposed to a disease but the people are already immunized against it, the risk of an epidemic will be lower. The vast majority of health professionals and researchers recommend immunizations, so you definitely should get them!
