Immunizations, also known as vaccinations or vaccines, are a medical tool used to protect individuals from specific diseases by stimulating the immune system to produce an immune response without causing the disease itself. Vaccines contain weakened or inactivated forms of the disease-causing microorganism (bacteria or virus) or a part of it (antigen).



Here's how immunizations work:

1. Vaccine triggers immune response.

2. Immune system produces antibodies and activates cells against vaccine antigens.

3. Body forms memory cells for future pathogen recognition.

4. Rapid immune response upon exposure prevents or reduces illness.

Common vaccines include those for measles, mumps, rubella, polio, tetanus, diphtheria, pertussis (whooping cough), hepatitis B, influenza, and many more.  Immunizations are a crucial tool in public health and have saved countless lives. They prevent the spread of many infectious diseases.
