Immunization is a world health and development success word, saving millions of lives each year. Vaccines reduce the risk of getting the disease by triggering the body’s natural defenses to build protection. The immune system responds when we get a vaccine shot. So, immunization is a vital element of primary health care and a valuable asset.
World Immunization Day is observed on November 10th with the aim of highlighting vaccination as a low-tech, cost effective, high impact solution to preventing illness and disease in individuals of all ages.
The terms vaccination and immunization are not the same. Vaccination is the term used for getting a vaccine in the form of an injection or an oral vaccine dose, while immunization is a process of getting immune to the disease following a specific vaccination. Some vaccines are given as shots, and some are given orally, but there is not much difference in the outcome. Timely vaccination and immunization is an important aspect.
