A baby with just a cold is not allowed to have a vaccination. The baby must be in good health during the vaccination period; no cold or fever before the vaccine can be given. You should not take your baby to get vaccinated if he or she has not fully recovered from a cold, or if he or she has just stopped taking his or her medication. Vaccination will have a certain effect on the baby’s body, and you should wait until the baby has fully recovered for ten days before giving the vaccine. After the vaccination, your child may also experience some discomfort, such as diarrhea, vomiting, allergies and other symptoms. After your baby has been vaccinated, he or she should be kept in the hospital for half an hour for observation to see if there are any adverse reactions. If your child has an abnormal reaction, you should consult your doctor if it is normal.
