Vaccine-Preventable Diseases

Vaccine-preventable diseases are illnesses that can be avoided through vaccination. Vaccines stimulate the immune system to recognize and fight specific germs, such as viruses or bacteria, preventing infection or reducing severity if exposed. Diseases like measles, polio, and influenza have vaccines that have significantly lowered their occurrence worldwide. Vaccination not only protects individuals but also helps create herd immunity, protecting those who cannot be vaccinated. Ensuring vaccination coverage is key to controlling or eradicating these diseases, ultimately saving lives and reducing health care burdens.
