Hi.... My son was 2 and half months old we do vaccination pentaxim painless and rota virus named rotarix. After 2 hours suddenly he stated crying... So we take him to the doctor immediately and that time his body becoming so cold so doctor told he has problem in breathing so we have to put your baby in ventilator doctor shows me that he is not getting enough oxygen. Level of oxygen was 48 to 55 after putting on ventilator my sons oxygen level was 60 average. So doctor told us that he has heart problem we should do ecg but in our city there is no doctor with portable ecg machine so we cannot do that after this on time the level of oxygen was 16. His heart was stopped working after pumping his heart it started again but next day doctor says there is no any recovery he will not live longer the he come out and say I am sorry we can t save your child.... So I want to know he has heart problem or not.. I think it was side effect of vaccination but doctor don t accept this doctor says he has heart problem.
