Does tetanus affect pregnant women?

Pregnant mothers should not abuse drugs during pregnancy, because general drugs have certain side effects, which can have a great impact on the baby in the belly and may even cause the baby to be born with congenital deficiencies or deformities. But if a pregnant woman gets a tetanus shot to prevent wound infection after getting injured on the skin surface, will this have a bad effect on the pregnant woman's body?

This has no impact. Do a good job of pregnancy checkups, do Down syndrome screening at 14-19 weeks of pregnancy, choose a suitable hospital at 20 weeks of pregnancy, create a pregnancy checkup card and do regular pregnancy checkups. After creating the pregnancy checkup card, generally check every four weeks before 36 weeks of pregnancy, and once a week after 36 weeks of pregnancy. If you feel any discomfort during this process, you can visit the doctor at any time to increase the number of examinations.

A four-dimensional color ultrasound is needed for prenatal screening when the pregnancy is 22-26 weeks. The four-dimensional color ultrasound can display the color, face, and development of various organs of the fetus in three dimensions, and even the status of the fetus in the mother's body can be observed; it can diagnose fetal malformations such as cleft lip, cleft palate, skeletal abnormalities, cardiovascular malformations, etc. at an early stage. Understand the dynamic process of the fetus in the uterus, and then dynamically record the fetus's posture in the uterus as a permanent memory. In addition, please note that it is best to avoid sexual intercourse during the first three months of pregnancy and after the seventh month of pregnancy to avoid miscarriage or premature birth caused by sexual intercourse. Take folic acid supplements under the guidance of a doctor within the first three months of pregnancy, start taking calcium supplements after 16 weeks of pregnancy, and get more rest and strengthen nutrition during pregnancy. Whether there is any impact depends on the gestational age, and also depends on what drug is being administered via drip.

1. Serious side effects of tetanus vaccine

Convulsions and coma, as well as brain damage are serious side effects of this vaccine. Severe allergic reactions may also include swelling of the mouth, difficulty breathing and wheezing, and possibly convulsions. But these side effects are extremely rare.

2. Moderate adverse reactions

Moderate side effects of the tetanus vaccine include vomiting, diarrhea, and high fever. Most cases are low-grade fevers, but occasionally they can exceed 39 degrees Celsius. These adverse reactions are rare.

3. Mild side effects

Mild side effects of tetanus vaccine include pain and redness and swelling at the injection site, which is also the most common adverse reaction. Other side effects include low-grade fever, headache, nausea, fatigue and muscle pain.

1. Pre-vaccination

It means that even if you are not injured now, you should get the tetanus vaccine first, so that you don’t have to worry about getting infected when you are injured. This is the highest level of so-called "preventive treatment", and most vaccinations are carried out according to this strategy. At present, the single tetanus vaccine has been eliminated, and the most commonly used are the diphtheria + pertussis + tetanus combined vaccine (DPT vaccine) and the diphtheria + tetanus combined vaccine (DPT vaccine). These two vaccines are free of charge in our country. Children should receive 4 doses of diphtheria, pertussis and tetanus vaccine before the age of 2, and 1 dose of diphtheria, pertussis and tetanus vaccine at the age of 6, which is equivalent to 5 doses of tetanus vaccine before the age of 6. Generally, its preventive effect on tetanus can last at least until the age of 16 or even longer.

2. Post-vaccination

The sooner the injection is given after an injury, the better. Generally, it should not exceed 24 hours, but it is still worth injecting after that (because the incubation period of tetanus infection is generally about one week, but the disease can occur as quickly as 24 hours, so the sooner the injection is given after an injury, the better). The protection time of TAT is about 2-3 days, and the protection time of TIG is 2-3 weeks. There is no absolute conclusion in clinical practice on this, but it is roughly within this range. If the risk of infection is faced again after this time, another injection is required. The duration of protection provided by active immunity obtained through injection of tetanus toxoid is relatively complicated, and you can consult your doctor. Generally speaking, if you are injured within 3 years after the last vaccination, you do not need to be injected with tetanus toxoid again. If it has been more than 3 years, you should get a booster injection. For severely contaminated wounds, in addition to the injection of tetanus toxoid, TAT or TIG may be injected at another site as appropriate. In fact, ideally, if someone has no history of immunization and is facing possible infection, in addition to being protected by an injection of TAT or TIG, they should also be injected with tetanus toxoid for active immunity if circumstances permit. However, due to clinical limitations such as individual and hospital reasons, this measure has not been taken, and the use of TAT or TIG alone is still the main method.

For pregnant women, the toxic effects of TAT or TIG are unclear and should be used with caution. However, tetanus toxoid (i.e. tetanus vaccine) is safe and, generally speaking, is used the same way as normal people. As for the prevention of neonatal tetanus, if the pregnant woman has been vaccinated with tetanus toxoid in the past, she only needs to receive a shot of tetanus toxoid in the early pregnancy, at the latest 3 weeks before delivery. The antibodies can cross the placenta to allow the fetus to also obtain this protective antibody. If the pregnant woman has not been vaccinated with tetanus toxoid in the past, she should receive another shot 4 weeks after the first shot as a booster.
