Nowadays, many families have pets. Can I get a rabies vaccination if I accidentally get scratched or scratched by a pet during pregnancy? Can you get a tetanus vaccination if you stab a nail? And so on. Many mothers-to-be have these questions. Vaccines can be broadly divided into two categories: “inactivated vaccines” and “non-inactivated vaccines”. For pregnant women, inactivated vaccines can be given, while attenuated or live vaccines cannot be given. 1. Inactivated vaccines are vaccines in which the microorganisms have been killed by chemical or physical means, and only the components of these microorganisms are sufficient to make the body immune. For example, tetanus vaccine can be used during pregnancy. 2. Attenuated or live vaccines are those made from microorganisms that have weakened their pathogenic power and they must be live in order for the body to develop immunity. For example, measles vaccine and rubella vaccine are such vaccines and are prohibited during pregnancy. What are the vaccines that are contraindicated during pregnancy? Measles vaccine, rubella vaccine, mumps vaccine, varicella vaccine, and BCG vaccine are all live attenuated virus vaccines. HPV vaccine is contraindicated during pregnancy There is no clear evidence that vaccination of pregnant women is harmful to the fetus, but because of insufficient research data, vaccination is not recommended during pregnancy. Can these vaccines be administered during pregnancy? 1. Hepatitis B vaccine is a recombinant vaccine, hepatitis A vaccine is an inactivated viral vaccine, and pneumococcal vaccine is an inactivated bacterial vaccine. These vaccines can be prophylactically administered to pregnant women who are exposed to high risk. 2. These vaccines can be administered to pregnant women, but are not routinely recommended: (1) meningococcal vaccine is an inactivated bacterial vaccine and is recommended during pregnancy in the case of unusual outbreaks; (2) typhoid vaccine is an inactivated bacterial vaccine and is not routinely recommended during pregnancy unless there is close, continuous exposure or travel to endemic areas. (3) These vaccines can be given during pregnancy in case of an unusual outbreak: (1) Rabies vaccine is an inactivated virus vaccine for prevention after being bitten or scratched by a dog or other animal and can be given during pregnancy; (2) Tetanus toxoid is used for prevention after a wound is contaminated and can be given during pregnancy. Globulin is a specific immunoglobulin that can be considered to be given to healthy pregnant women exposed to varicella to protect the mother rather than to prevent congenital infection of the fetus. Breastfeeding women can receive any vaccine. Breastfeeding does not affect the vaccine and the vaccine does not affect breast milk. If a woman preparing for pregnancy receives a vaccine that is contraindicated during pregnancy, then it is recommended that the vaccine be given one month before pregnancy. Finally, there is no evidence that any vaccine given during pregnancy causes fetal health damage, and even if a live virus vaccine is contraindicated, the effect on the fetus is unknown, so it is not recommended to easily terminate a pregnancy because of such vaccinations.
