Introduction
Vaccination is a medical process designed to protect individuals from infectious diseases. It involves administering a vaccine, which is a substance that stimulates the body’s immune system to recognize and fight specific pathogens, such as viruses or bacteria.
Here’s a simple breakdown of how it works:
- Vaccine Introduction: A vaccine contains parts of the pathogen (like proteins or weakened/killed versions of it) that do not cause disease but trigger an immune response.
- Immune Response: Once the vaccine is introduced into the body, the immune system recognizes these foreign substances and produces antibodies. These antibodies are proteins that specifically target and neutralize the pathogen.
- Immunity Development: The immune system also creates memory cells that remember how to fight the pathogen in the future. This means if you are exposed to the actual disease later, your immune system can respond more quickly and effectively.
- Protection: By building this defense, vaccines help prevent the occurrence of disease and reduce the spread of infectious diseases within communities.
Overall, vaccines are a crucial tool in maintaining public health and preventing outbreaks of infectious diseases.
Vaccines reduce risks of getting a disease by working with body’s natural defenses to build protection. Vaccination keeps you healthy and free from preventable diseases and curbs the spread of diseases from one person to the other.
