Forty days when the baby is on fire and mute throat, it is recommended not to vaccinate for the time being, which may aggravate the infant’s physical discomfort and lead to aggravation of the condition. After vaccination, babies may have some adverse reactions, such as mild fever, abdominal pain, diarrhea, etc. Because infants and young children can not accurately express their own symptoms and sensations, when there is organic discomfort, infants may be manifested as violent crying, and violent crying may cause a certain degree of impact on the infant’s throat, and even aggravate the severity of the infant’s mute voice. When a forty-day-old baby has a mute throat on fire, attention should be paid to whether the indoor temperature is too high, the air is too dry and other reasons, and at the same time, attention should be paid to whether the infant is suffering from colds and other illnesses, and timely treatment should be carried out to improve the environmental conditions, and to promote the infant’s recovery of health as soon as possible. After the condition improves, you can choose a suitable date to make up the vaccine under the guidance of the doctor.
