💉 Vaccine: Protecting Health Through Immunization
HOOK
Vaccines are among the most effective public health interventions ever developed. By training the immune system to recognize and fight harmful pathogens before illness occurs, they have helped prevent millions of deaths and significantly reduced the burden of infectious diseases worldwide.
HISTORY / OVERVIEW
Vaccine works by exposing the immune system to a harmless form or component of a pathogen, or instructions for making one, allowing the body to develop an immune response and immunological memory without causing the disease itself.
Vaccination programs have played a major role in controlling or eliminating many infectious diseases and continue to be an essential part of preventive healthcare.
