Good day Dr. Jain. I just would like to ask the effect of Antitetanus Serum (Tetanus Antitoxin Vaccine) if accidentally given to a pregnant mother. I have a friend who is 2months pregnant and had an accident sustaining laceration on her left arm. The doctor ordered tetanus shots: toxoid and tetanus antitoxin given intramuscularly because my friend failed to mention that she is pregnant. It was too late when she mentioned that she is pregnant, after the nurse injected the vaccines. I have heard toxoid is being given to pregnant mothers but tetanus antitoxin should not be given because it is abortifacient or can cause abortion. What measure or immediate management can be done to prevent the effect of vaccine given. she actually received 3 ampules of antitetanus (4,500 I.U). hope to see your reply asap. thank you. Ernie D.
