If the baby only has a red anus and no other symptoms, this condition is vaccineable and vaccination is usually only suspended when there is an infectious disease such as upper respiratory tract infection, enteritis or other diseases. This is because vaccines are mainly attenuated or inactivated viruses and bacteria. If the vaccine is given during the child’s illness, the child’s resistance and immunity are very low at that time, and if the vaccine is given, the child may get sick directly. Therefore, it is generally not recommended to give the vaccine to the child when the child is sick, and the vaccine should be given only after the child has recovered from the illness for at least one week. Most of the baby’s anal redness is caused by diarrhea or the use of diapers, it is recommended to keep the child’s buttocks dry and can be treated by smearing the child with Bactroban ointment.
