What defenses does the body have to fight measles?

The body employs several defenses to fight measles, primarily through the immune system. Upon infection, the immune system activates T cells to target and destroy infected cells, while B cells produce antibodies that neutralize the virus and prevent its spread. Additionally, the innate immune response initiates inflammatory reactions that help contain the virus. Vaccination with the measles, mumps, and rubella (MMR) vaccine is also a crucial preemptive defense, as it stimulates an immune response without causing the disease.
