Chickenpox vaccine, influenza vaccine, and hepatitis A vaccine can be injected according to your own needs. You can consult your doctor to make a choice and receive pre-pregnancy injections.
(1) Varicella vaccine:Varicella-zoster virus causes fetal infection, which can have serious consequences and lead to a variety of birth defects, such as paralysis, muscle atrophy, and polydactyly. (toes), brain atrophy, cerebellar hypoplasia, club feet, congenital cataracts, repeated convulsions, etc., and the mortality rate is quite high. At the same time, it may cause severe pneumonia or even death in pregnant women. There is currently no specific drug for the varicella-zoster virus, and prevention of infection is still the main approach. The chickenpox vaccine can be injected before pregnancy. Women who have had chickenpox before pregnancy can be pregnant with confidence. Women who have not suffered from the disease and are planning to become pregnant must get the chickenpox vaccine 3 to 8 months before pregnancy.
(2) Influenza vaccine: Influenza viruses are very common, and spring and winter are the best times for influenza outbreaks every year. Strong influenza viruses may cause teratogenicity in the fetus, or cause miscarriage due to the combined effect of high fever and viruses that stimulate the contraction of the uterus.
During the influenza virus epidemic season, women can prevent influenza virus infection by getting the influenza vaccine early before pregnancy. The vaccine should be injected at least 3 months before pregnancy. If it is injected too late, it will not be good for the body to produce antibodies. The vaccine virus may also be injected in too short a time. If it disappears, it will have an adverse effect on the fetus. Generally, immunity lasts for about 1 year after vaccination.
In the northern region, injections are administered at the end of October or early November each year, and in the southern region, injections are administered at the end of November or early December each year. You should wait 3 months after getting the flu vaccine before getting pregnant.
(3) Hepatitis A vaccine: Hepatitis A virus can be transmitted through water sources and food. Due to endocrine changes and increased nutritional requirements during pregnancy, the burden on the liver increases, and the ability to resist viruses is weakened, making it extremely susceptible to hepatitis A virus infection. Hepatitis A will not be transmitted to the fetus, but it will cause serious harm to pregnant women. If severe hepatitis develops during pregnancy, it will not only endanger the life of the pregnant woman, but also cause abnormal death of the fetus. Therefore, experts recommend that high-risk groups (women who often travel for business or often eat out) should inject hepatitis A vaccine at least 3 months before pregnancy (preferably 6 to 8 months before pregnancy), which can prevent and resist diseases while also ensuring The body has enough time to eliminate the virus and produce antibodies. Hepatitis A vaccination can maintain immunity for at least 20 years.
