Measles is a contagious viral infection that mainly affects children. It is brought on by a virus from the paramyxovirus family and spreads by airborne and direct contact. The symptoms appear 14 days after exposure and include a rash, high fever, cough, runny nose, and watery eyes (WHO, 2023). Vaccination involves introducing a vaccine into the body to provide protection against a specific disease. In this case, the vaccine against measles contains antigens, which are substances that produce an immune response from white blood cells, specifically B-cells (Greenwood, T., Pryor, K., Bainbridge- smith, L., 2018), in order to distinguish its own tissues from foreign materials such as bacteria, viruses, and toxins, and to prevent them from attacking the body itself (Dutta, 2020). The type of vaccine used for measles is a formulation that elicits an immune response, consisting of two pragmatically scheduled vaccination: “measles-‐containing vaccine dose 1” and “measles-‐containing vaccine dose 2” (WHO, 2009).
