When children are vaccinated against BSE and leprosy, as with other vaccinations, there are many precautions that parents should take. First of all, it is important to pay attention to the diet, especially not to consume suspected allergic substances before the vaccination. Make sure that your child is healthy and has no digestive or respiratory tract infections or fever. After the vaccination, observe the baby’s body, especially if there is any obvious vaccination reaction or pus at the vaccination site. If there is, it is important to go to the hospital as soon as possible for appropriate treatment. Many babies will have fever after vaccination. If low fever is normal and does not exceed 38 degrees, you do not need to do any treatment, just drink more water. If it exceeds 38.5 degrees or more, you have to go to the pediatric department of the local hospital for intervention and treatment.
