Generally, people with egg allergies can get the MMR vaccine. The MMR vaccine contains measles, which is prepared by culturing chicken embryo fibroblasts, and does not contain egg ovalbumin, so egg-allergic people can generally take the MMR vaccine. MMR vaccine is a triple vaccine, which can prevent measles, mumps and rubella at the same time, and has the high efficiency of “three vaccines in one”. However, MMR vaccine is a live attenuated vaccine, after vaccination, the baby will have a slight infection process, which will stimulate the body to produce antibodies and play a protective role. After vaccination, there may be some mild reaction of measles, mumps and rubella, which are normal phenomenon and parents do not need to worry too much.
