Vaccination is the most effective way to prevent infectious diseases. Vaccination for children has become a consensus in society, but people's understanding of adult vaccination is still far from the same. There is a lack of understanding of vaccination for pregnant women and there are great prejudice.
Pregnant women should be given scientific vaccine
Chinese people have very incorrect understanding of the protection of pregnant women, including most doctors. People think that pregnant women are precious and must be cautious in everything. When it comes to vaccines, try not to get vaccinated as much as possible. This view has no clinical evidence. The existing clinical evidence is exactly the opposite of this view. A considerable number of diseases, especially infectious diseases, may cause the fetus to have low birth weight, birth defects, premature birth, miscarriage and death. Some diseases may also affect pregnant women and even lead to death in pregnant women. The reason why pregnant women are special is that they and the fetus in their stomachs are more sensitive to these infectious diseases and their complications than normal people and are prone to serious symptoms. To protect pregnant women and fetus, we should start by avoiding infectious diseases as much as possible. The best way is to get vaccinated. The safety of
vaccine is the most concerned issue for people. Caution is necessary, but caution must be based on clinical evidence, not on assumed imagination. Excessive caution is a huge risk of infectious diseases with uncertain or unfounded safety issues for pregnant women and fetus that may be infected with serious consequences. According to the existing materials, generally speaking, most vaccines are safe for pregnant women, and whether they should be vaccinated needs to be analyzed in detail.
may have serious impacts on pregnant women and fetus, and the pathogens that can be prevented are the following
1, rubella virus
0 Pregnant women should be vaccinated from when preparing for pregnancy, and the first thing to consider is rubella vaccine.
Rubella virus infection can lead to severe birth defects and even death in the early stages of pregnancy. Therefore, you need a blood test before pregnancy to see if there are antibodies to the rubella virus. Most people were vaccinated with the triple vaccine of measles, mumps and rubella (MMR) when they were young, but they still had to be sure to have antibodies against the rubella virus. If not, you should get the MMR vaccine. However, do not get pregnant within one month after vaccination. It is best to wait until the blood test shows the rubella virus antibody before getting pregnant. The main reason for waiting for one month after vaccination is that the MMR vaccine is prepared with attenuated strains, which may theoretically lead to fetal infection, but there are no such clinical cases. However, the authoritative agency still recommends not getting pregnant for one or two months after vaccination with MMR vaccine, and not being vaccinated during pregnancy, but being vaccinated immediately after giving birth.
2, influenza virus
Mothers suffer from influenza will cause serious consequences such as fetus from low weight to miscarriage. After suffering from influenza, pregnant women may also have premature birth, miscarriage or even death of pregnant women. Therefore, pregnant women are one of the high-risk groups for influenza.
However, the Chinese medical community is not in line with the international community in terms of whether to get influenza vaccine. Most doctors believe that pregnant women cannot get influenza vaccination, and a very small number of experts who agree that pregnant women get influenza vaccination also recommends getting in vitro after three months of pregnancy.
The swine flu epidemic in 2009 has led to an exponential increase in the influenza vaccination rate of pregnant women in the United States, and also provides an opportunity to observe whether the flu vaccine is safe for pregnant women. The results show that influenza vaccine is absolutely safe for pregnant women. The authoritative organization randomly revised the guidelines, suggesting that pregnant women should be vaccinated immediately after the annual influenza vaccine is launched, and vaccination with influenza vaccine is a top priority.
Since influenza vaccines need to be vaccinated every year, if pregnancy spans the year, that is, between September and October, you must receive the influenza vaccine for two years, because babies have to wait until 6 months before they can get the influenza vaccine, and they can only rely on the protection provided by breast milk. Therefore, not only should they have immunity to the influenza virus during pregnancy, but they should also have immunity to the influenza virus during breastfeeding.
3, Pertussis bacillus
Like rubella, whooping cough is also a disease that can be prevented by vaccination in childhood.The previous authoritative agency suggested that pregnant women who have not received the pertussis vaccine should receive the pertussis vaccine. Now, the suggestion is that all pregnant women should receive the pertussis vaccine every time they get pregnant.
There are two types of pertussis vaccines, both pertussis, tetanus and diphtheria triple vaccines. DTap is given to children aged 2 months to 6 years old, Tdap is given to 11-year-old doctors and adults, and Tdap is given to pregnant women.
Pregnant women receive Tdap mainly for their children, because whooping cough infection may cause the child to stop breathing. Babies must wait until two months after birth to receive the first dose of DTap, so there is a window period . It is best for pregnant women to receive Tdap vaccine between 27 and 36 weeks of pregnancy, so that the mother's antibodies can be transmitted to the fetus, which can cover this window period. The immunity obtained by only one vaccination cannot be maintained at a high level, so Tdap must be re-inoculated in the later stages of pregnancy so that the fetus can gain enough immunity to whooping cough. The safety of the
DTap vaccine for pregnant women has not been confirmed yet, so pregnant women should not receive this vaccine.
4, Hepatitis B virus
Hepatitis B virus vaccine is the first cancer vaccine. By preventing infection with hepatitis B virus, the possibility of liver cancer in the future can be reduced. Especially in China, the major hepatitis B countries, the importance of hepatitis B vaccine is more significant.
If pregnant women are infected with hepatitis B virus, about 40% of babies will become chronic hepatitis B infection, and one-quarter of them will die sooner or later from chronic liver disease.
According to currently limited clinical data, the hepatitis B vaccine is safe for pregnant women. However, the US CDC does not recommend vaccination for pregnant women because the rate of hepatitis B infection in the United States is not high, but rather recommends that high-risk pregnant women, that is, pregnant women with hepatitis B infection sources around them, should be vaccinated. For the Chinese environment, there are many sources of hepatitis B infection. If you do not have immunity to the hepatitis B virus, it is worth considering getting the hepatitis B vaccine.
5, other pathogens
Although the vaccine is safe overall, the safety of some vaccines for pregnant women has not been determined yet, and it is not recommended for pregnant women to receive vaccination at present.
One of these types may be vaccinated under special circumstances. For example, hepatitis A vaccine. The safety of hepatitis A vaccine for pregnant women has not been determined yet, and pregnant women are not recommended to get this vaccine. But there are exceptions. If a pregnant woman suffers from chronic liver disease, in order to protect her liver, doctors may recommend that pregnant women receive hepatitis A vaccine. Also, if pregnant women are traveling, doctors may recommend pregnant women to get the hepatitis A vaccine.
Similar situations include meningitis vaccine. For pregnant women who are engaged in related work or traveling, doctors may recommend getting meningitis vaccine.
also belongs to this category of pneumonia vaccine. If there is a high-risk or chronic disease, doctors may also recommend vaccination.
Another type is not to be vaccinated during pregnancy. For example, the MMR vaccine mentioned above, which also belongs to this vaccine, chickenpox vaccine, and you should not get pregnant within one month after vaccination.
polio vaccine does not require vaccination. First, the safety is uncertain, and second, unless in some developing countries, the risk of infection is very low.
In short, pregnant women should not only not exclude vaccines, but also actively receive the recommended vaccines.
