Vaccines are one of the most cost-effective tools for maintaining healthy and active communities. By helping prevent illness, vaccines lower healthcare costs, reduce missed work and school days, and help keep daily life running.
Vaccines are a powerful tool to help keep you healthy. They teach your immune system to fight disease—without the dangers of full-blown infection. Much like eating a balanced diet, exercising on a regular basis, and going for annual check-ups, staying up to date with recommended vaccines is an essential part of a healthy, prevention-focused lifestyle.
