Immunizations: Vaccine-Preventable Diseases

Vaccines are one of the best ways to protect the health of our community. Before vaccines, many people died from diseases we now can prevent.

The viruses and bacteria that cause these diseases still exist. That’s why it’s important for everyone to get the vaccines they need on time.

We offer resources on diseases that can be prevented with a vaccine. For many of these diseases, we explain:

  • How it spreads.
  • Signs and symptoms.
  • Treatment.
  • Prevention.
  • Vaccines recommended by the Centers for Disease Control and Prevention (CDC).
  • Resources for learning more about the disease and its vaccine.
  • Data and statistics for the most common illnesses and vaccinations.
  • Information just for health care providers.
