Definition of Vaccine

Definition of Vaccine

• A vaccine is a biological preparation that provides active acquired immunity to a particular infectious disease.
• It typically contains an agent that resembles a disease-causing microorganism and is often made from weakened or killed forms of the pathogen, its toxins, or one of its surface proteins.
• Vaccines stimulate the body’s immune system to recognize the agent as foreign, destroy it, and "remember" it, thus allowing the immune system to recognize and combat the pathogen in future encounters.
• Vaccination is the process of introducing a vaccine into the body to produce immunity.
• Vaccines can be administered via injection, orally, or nasally.
• The development and distribution of vaccines are critical public health strategies for the prevention of infectious diseases.

Definition of Vaccine

• Biological preparation that grants active acquired immunity to specific infectious diseases.
• Contains agents resembling disease-causing microorganisms, often derived from weakened or killed pathogens, their toxins, or surface proteins.
• Stimulates the immune system to recognize foreign agents, leading to their destruction and the establishment of memory for future encounters.
• Vaccination is the process of introducing a vaccine into the body to develop immunity against diseases.
• Administered through various routes: injection, orally, or nasally.
• Critical public health strategy for preventing infectious diseases through development and distribution of vaccines.
