What are Vaccines?
Vaccines are biological preparations designed to provide immunity against specific infectious diseases. They contain components that mimic disease-causing microorganisms, such as bacteria or viruses, but are not capable of causing the disease themselves. These components can be weakened or killed forms of the pathogen, or fragments like proteins or sugars.
When administered, vaccines stimulate the body's immune system to recognize and fight the pathogens if encountered in the future. This process helps prevent illnesses and can control the spread of infectious diseases. Vaccines have been instrumental in reducing, and in some cases eradicating, diseases such as smallpox, polio, and measles.
Vaccination is a key public health strategy that protects both individuals and communities through herd immunity, where a large portion of the population becomes immune, thereby reducing the chance of disease spread.
