Vaccines are biological preparations designed to provide immunity against specific Infectious Diseases. They work by stimulating the immune system to recognize and fight pathogens, such as viruses or bacteria, without causing the disease itself. By introducing weakened or inactive components of the pathogen, vaccines prepare the body to respond more effectively if exposed to the actual disease in the future. This helps prevent illness, reduces transmission, and contributes to public health by promoting herd immunity.
