Coupling infection

If the child happens to be in the incubation period of a certain disease, or the child has just had a vaccination taboo stipulated in the vaccine instructions. After vaccination, the child's original disease is acute or new condition. This kind of adverse reaction is coupling infection.

To prevent coupling infection, parents need to do two things well. One is to master the child's physical condition.
