Vaccinations are not allowed for babies with a cough. Babies in a state of illness, whether it is a viral or bacterial infection, increase the risk of a vaccine reaction. Also due to the presence of infection, the effect of the newly vaccinated vaccine will be greatly reduced, so if the baby is in a state of illness, there is no need to give the vaccination. Vaccination should be given after healing, and it is better to go for vaccination after 10 days of stopping medication. Even in the case of a mild runny nose and other colds, do not blindly vaccinate, because the disease has a gradual aggravation of the process. If the symptoms worsen after vaccination, the same will still have an effect on the vaccine. Before the vaccination, you should give your child a bath, because you can’t take a bath within 24 hours of the vaccination. Stay in the hospital for half an hour after the vaccination to observe your child. If your child has any adverse effects, consult your doctor to see if it is normal, and if not, follow the doctor’s instructions.
