Vaccination is the administration of a vaccine to stimulate the body's immune system to develop protection against infectious diseases. Vaccines are a critical tool in preventing the spread of diseases and have been instrumental in eradicating deadly diseases such as smallpox.

It is essential to stay up-to-date with recommended vaccination schedules and to discuss any concerns or questions with a healthcare provider. By getting vaccinated, individuals can protect themselves and their communities from infectious diseases.
