Measles, mumps and rubella (MMR) are dangerous diseases that can be fatal to children. The MMR vaccine is given to children at a young age to produce antibodies against these diseases. Describe how giving the vaccine leads to the production of antibodies.
The vaccine contains weakened or dead antigens (from MMR). These antigens are displayed on antigen-presenting cells which are detected by a specific helper T cell. This stimulates a specific B cell which divides resulting in plasma cells. Plasma cells produce the antibodies against MMR.
