What is immunaization?

Immunization is the process by which a person becomes protected against a disease by the administration of a vaccine. Vaccines are biological preparations containing either weakened or killed forms of a pathogen, or parts of a pathogen, that are administered to stimulate an immune response in the recipient. When a person is immunized, their immune system produces antibodies against the pathogen, which provides protection against future infection.

Immunization is one of the most effective ways to prevent the spread of infectious diseases and has saved millions of lives around the world. It is essential for public health and is recommended by medical professionals for all individuals, unless there are specific contraindications.

Vaccines are usually administered through injection or orally. The type of vaccine and the schedule of administration depend on the specific disease and the individual's health status. Some vaccines provide long-term protection, while others require booster doses to maintain immunity.

Immunization is a safe and effective way to protect individuals and communities from infectious diseases. It is an important part of preventive healthcare and is essential for global health security.
