Pay attention to vaccination during pregnancy. What are the possible hidden dangers?

Vaccination is generally not recommended during pregnancy.

You can't play live attenuated vaccine during pregnancy. You can't take active attenuated vaccine in the first three months of pregnancy. Active attenuated vaccine is made of pathogenic microorganisms and their metabolites with weak or non-toxic immune activity, which not only stereotypes reproduction, but also affects the fetus. Playing live attenuated vaccine before or during pregnancy is easy to cause fetal malformation.

Inactivated vaccine can be given after being evaluated by a doctor during pregnancy. Inactivated vaccines are processed dead bacteria, which use their antigenicity to cause human immune response and cause defensive antigens, and generally do not easily affect the fetus. After pregnancy and pregnancy, it is considered necessary by doctors to fight. For example, the flu vaccine is an inactivated vaccine.

Under special circumstances, it is necessary to consult a doctor before vaccination. Like rabies vaccine. Rabies vaccine is not recommended in the first trimester. If a pregnant mother is bitten by a small animal, consult a gynecologist. Generally, the bite is more serious. With the consent of the gynecologist, she can get rabies vaccine. During pregnancy and pregnancy preparation, pregnant mothers want to get vaccinated, so it is necessary to consult a professional doctor, and the specialist will decide whether to get vaccinated.

China's "China Pharmacopoeia" prohibits pregnant women from vaccinating, and there is no vaccine instruction for pregnant women in China, except rabies vaccine. Because rabies virus is a disease with a very high mortality rate, pregnant women who are bitten by dogs can be vaccinated with rabies vaccine, but pregnant mothers should also postpone vaccination with rabies vaccine for pre-exposure prevention.

Theoretically speaking, pregnant women should avoid contraception within 3 months after receiving live attenuated vaccine, but if they are not careful during pregnancy, there is no need to be too anxious, and there is no need to terminate pregnancy. Retrospective analysis in the United States and Brazil shows that pregnant mothers were accidentally vaccinated with varicella vaccine and rubella vaccine, and the newborn baby did not have congenital diseases.

Therefore, considering comprehensively, "live vaccine" is not suitable for vaccination during pregnancy; When there is a risk of rabies virus after being bitten, rabies vaccine should be vaccinated immediately; In other high-risk situations, it is necessary to know the vaccinator and guide the vaccination of inactivated vaccine, but it is not suitable for vaccination in the first trimester.
