Preventive Vaccines

Preventive vaccines are medical treatments that help your immune system recognize and fight specific diseases before you get sick. They usually contain a safe part of a virus or bacteria, or a weakened version, prompting your body to build defenses without causing illness. This prepares your immune system to respond quickly and effectively if you encounter the actual pathogen later. Vaccines are a proven way to protect individuals and communities from serious, potentially life-threatening diseases, reducing their spread and contributing to overall public health.
