Many parents of children ask: Doctor, can children with precocious heart disease be vaccinated? In fact, most children with congenital heart disease should be vaccinated according to the normal schedule, and only a small percentage of children with congenital heart disease cannot be vaccinated. Heart function is the key The vast majority of children with congenital heart disease can be vaccinated according to the standard vaccination schedule. In children with congenital heart disease who do not have altered heart function, vaccination will not have a serious impact on children with congenital heart disease. In contrast, these children are more susceptible to diseases (such as pneumonia) than healthy children because of their heart defects, and when they do contract a disease, it is more difficult to cure, so vaccination is even more important. For example, small ventricular septal defects, atrial septal defects, patent ductus arteriosus, and pulmonary valve stenosis should all be vaccinated as standard on a schedule if they do not have cardiac insufficiency. Only those children with cyanotic congenital heart disease (such as tetralogy of Fallot or other complex malformations), or those with congenital heart disease who have developed cardiac dysfunction, should not be vaccinated. For children who have undergone radical surgery for congenital heart disease, they need to wait for complete recovery of heart function (about six months) before vaccination can be administered. Therefore, there is no theoretical basis for this statement that vaccination cannot be given for congenital heart disease. Precautions for vaccination of children with precocious heart disease In addition to routine physical examination, children with precocious heart disease should undergo a strict cardiac specialist examination, including electrocardiogram, echocardiogram, and cardiac ultrasound, before vaccination, and only with the consent of a cardiologist. 1. Vaccination time After 3 months after precordial surgery, if the heart function is good after reexamination, vaccination should be done according to normal procedures. Pre-operative vaccination is in accordance with medical advice, and close observation should be paid attention to. 2.Growth and development The baby’s growth and development are normal, with height and weight in the normal range, not lower than the local standard for normal children of the same age. 3. Physical condition Choose to vaccinate when the baby is in good health, without cold, cough, fever, rash, diarrhea, etc. If you have a cold, it is recommended to wait for a week after healing before vaccination. 4.Vaccines ① Vaccine selection Vaccines are divided into live attenuated vaccines and inactivated vaccines. Premature babies are weak, so try to receive inactivated vaccines with little side effects and advocate vaccination with combination vaccines. The advantage of combined vaccines is that the number of vaccinations is less, the side effects are less, and the preventive effect is the same. For example, only 4 doses of the pentavalent vaccine are required, while a total of 12 doses are required for a single vaccination. The observation time at the clinic after vaccination should also be longer, such as one hour. The next step of vaccination will be determined based on the reaction after vaccination. ② Interval time Each vaccine has a certain interval time. Live attenuated vaccines generally cannot be vaccinated with other vaccines within 27 days of vaccination, while inactivated vaccines are within 6 days. The interval between the booster vaccine and the basic vaccination of the same vaccine should be as required. ③ No simultaneous vaccination If two vaccines are given at the same time, it is recommended that only one vaccine be given at a time. Simultaneous vaccination may increase the probability of adverse reactions. ④ Desensitization injection Consult your local vaccination doctor about the possibility of desensitization in separate doses to reduce adverse reactions. Pay attention to anti-sensitization treatment in case of discomfort.
