My son age 7 years by mistake today at school made 4 th vaccinated against hepatitis B, although the third target was made just a week ago. The child said that he could not make shots without the knowledge of parents as he is also allergic. Despite the fact that all supporting documents have to hold 3 shots at the doctor were he underwent another. How much it is dangerous to his health? What might be the consequences? What better to do in this situation?
