It may seem like a new thing for women to get vaccinated before getting pregnant. Because children are generally vaccinated, they are young and have low immunity. They need vaccinations to build immunity against diseases such as measles, whooping cough, diphtheria, tetanus, polio, hepatitis, chickenpox and pneumonia. …
So why do women of childbearing age need to be vaccinated before becoming pregnant? Its purpose is to ensure the normal development of the fetus and reduce the birth of sick and disabled children. Take congenital heart disease as an example. It is a serious congenital malformation that brings great harm to the child\’s development and also brings heavy mental pressure and financial burden to the family. Is there any way to prevent congenital heart disease in the fetus? The solution is to get vaccinated against rubella. Although there are many factors that contribute to the development of congenital heart disease, infection with rubella virus is the main cause of congenital heart disease.
Vaccine classification
At present, vaccines are divided into live attenuated vaccines, inactivated vaccines and genetically recombinant vaccines.
Live attenuated vaccines are cultured and propagated from attenuated or non-toxic but highly immunogenic pathogenic microorganisms and their metabolites, which can achieve long-term or lifelong protection. Pregnant women are advised not to use this type of vaccine.
Inactivated vaccines are processed dead pathogenic bacteria that use their antigenicity to cause the body\’s immune response and produce protective antibodies. Multiple repeat injections are needed for long-term protection. This type of vaccine will not affect the fetus after vaccination, and pregnant women can safely receive it when needed.
Genetic recombinant vaccines are vaccines that integrate part of the gene fragments of the virus into other microorganisms so that they can continuously replicate to produce viral antigen parts. This type of vaccine can also cause the body to produce antibodies without causing adverse reactions to the body.
