Immunization

Immunization is the process of protecting an individual from infectious disease by introducing a vaccine, which stimulates the body's own immune system to recognize and fight against a disease-causing agent (pathogen). Immunization can protect against several infectious diseases, including measles, mumps, rubella, tetanus, and diphtheria. Vaccines can also protect against certain types of cancer, such as human papillomavirus (HPV), and other chronic virus infections. Immunization is the most effective way to prevent the spread of infectious diseases and is necessary for overall public health. Vaccines are safe and effective, and are recommended for people of all ages.
