Fever on the eighth day of MMR vaccine is mainly due to the adverse reaction of the vaccine. Fever can be treated by physical cooling, such as using warm water to wipe the whole body, the evaporation of water can take away most of the heat from the body surface; at the same time, the room temperature can be lowered, and attention can be paid to ventilation, etc. However, if the fever is not relieved or if high fever occurs, medical treatment is needed.
However, if the temperature does not drop significantly after physical cooling, or if a high fever of 38.5℃ or above occurs, then timely medical treatment is needed.
