Pregnant women who have been bitten by a dog can reduce the risk of wound infection by promptly cleaning and disinfecting the wound, but rabies prevention requires rabies vaccination. Will the vaccination affect the growth and development of the fetus in the womb? There is no scientific basis for the belief by some that rabies vaccination can endanger the fetus. A study of 190 pregnant women and their newborns after rabies vaccination following rabies bites was reported, with a follow-up period of one year, and the results were compared with those of babies born to women who were not bitten by rabies. The results showed that in the rabies bite group, the spontaneous abortion rate was 4.2%, placenta praevia was 0.5%, gestational diabetes was 1.6%, neonatal birth defects were 0.5%, and low birth weight infants were 2.9%, while in the control group, the spontaneous abortion rate was 5.6%, placenta praevia was 1.6%, gestational diabetes was 1.3%, and neonatal birth defects were 1.3%. The incidence of neonatal birth defects was 1.0%, and the incidence of low birth weight babies was 9.9%. The incidence of adverse reactions, such as fever, myalgia, headache, fatigue, and redness at the injection site, was similar to that of normal people after the vaccine was administered to pregnant women, with no significant differences. The above survey data show that rabies vaccination is safe for both pregnant women and fetuses after rabies bites are treated according to the treatment routine. In addition, it has been reported that the results of a survey of nearly 1,500 pregnant women who received rabies vaccine after being bitten by a dog showed that no cases of fetal harm or malformation were found. According to the research and practice of medical experts in Russia, Japan and the United States, rabies vaccination for pregnant women has been shown to be effective in preventing the occurrence of rabies in both mother and child. It can be seen that rabies vaccination of pregnant women does not affect the normal growth and development of the fetus, and there is no need to worry about it. It is worth pointing out that local treatment of animal bites or scratches by dogs is very important and can greatly reduce the incidence of rabies. The sooner the wound is treated, the better, and it must be cleaned even after a few hours or days, because the rabies virus generally stays at the wound for 3 days. The method is to rinse with water, tap water or 20% soapy water for more than 15 minutes, without bandaging, and then go to the local hospital as soon as possible for formal and thorough treatment again. Therefore, when a pregnant woman is inadvertently bitten by a dog, she should immediately rinse and disinfect the wound to the hospital for debridement and then administer rabies vaccine to protect the safety of the mother and child. Delaying or refusing treatment due to concerns about the possible adverse consequences of rabies vaccination may instead be costly.
