请与您的医生讨论乙型肝炎 疫苗。如果验血表明您并未患有乙型肝炎，则医生可能希望等到宝宝出生之后给您注射疫苗。如您的先生或性伙伴患有乙型肝炎，如您与患有乙型肝炎的家人有密切 接触，或者如果您的工作使您有被传染的高风险，则您的医生可能希望开始注射疫苗。但是，您必须与您的医生共同作出这项决定。
1.务必在您分娩前数周提醒您的医生进行乙型肝炎疫苗注射，并在可能情况下注射一剂乙型肝免疫球蛋白(HBIG)。您 的医生事务繁多，因此可能会忘记嘱咐注射此类药物。即使无法获得乙型肝炎免疫球蛋也并不必过于担心。乙型肝炎免疫球蛋白是一种能够提升疫苗功能的药物，但 其重要性不如疫苗本身。
为了保护您的宝宝不受到慢性感染，必须在其出生后12个小时以内注射疫苗。这是一个持续时间很短的机会。您没有第二次 机会！如在宝宝出生后12个小时以内注射疫苗，则您的宝宝有95%的机率获得保护，不受到乙型肝炎病毒感染。如未能正确地注射疫苗 ，则您的宝宝非常可能终生受到乙型肝炎的慢性感染。
Pregnant Women and Hepatitis B
Should I get tested for hepatitis B if I am pregnant?
Yes, ALL pregnant women should be tested by their doctors. But women of Asian descent must be tested since they are at much higher risk for hepatitis B infection.
If I am pregnant, should I get vaccinated?
Talk to your doctor about the hepatitis B vaccine. If your blood tests show that you do not have hepatitis B, then he or she may want to wait until after the baby is born. If your husband or sexual partner has hepatitis B, if you live in close contact with a family member who has hepatitis B, or you have a job that places you at high risk for infection, then your doctor may want to start the vaccine. But this is a decision you must make with your doctor.
If I have hepatitis B, will my unborn baby be affected?
Hepatitis B does not usually affect the health of your unborn baby. And most pregnant women with hepatitis B do not have any problems. But, it is important for the doctor to know whether you have hepatitis B so they can watch you closely throughout your pregnancy.
If I have hepatitis B, how can I infect my newborn baby?
You can pass the virus on to your newborn baby during delivery. When a woman goes into labor, there is a massive exchange of blood -- the virus is passed in the mother's blood to the newborn through the umbilical cord. The blood exchange occurs before delivery. Therefore, you cannot prevent infecting your newborn by choosing to have a C-section. The hepatitis B virus is passed whether you give birth naturally or through surgery.
Why is it so serious if my newborn is infected with hepatitis B?
Newborns who are exposed to hepatitis B have more than a 90% chance of becoming chronically infected. Their immune systems are not able to get rid of the virus, so they can become a "chronic carrier". This means the virus stays in their liver for a long time. They can pass the virus on to others. They will also live with a greater chance of developing serious liver disease later in life
If I have hepatitis B, what can I do to protect my newborn?
The good news is that there is a vaccine to protect your newborn baby. But you have to make your newborn is vaccinated in the delivery room.
* Make sure to remind your doctor several weeks before you deliver to order the hepatitis B vaccine and if possible, one dose of hepatitis B immuneglobulin (HBiG). Your doctor has many things on his mind, so he may forget to order these drugs. If the HBiG drug is not available, don't get upset. HBiG is a drug that can help increase the effectiveness of the vaccine, but it is not as important as the vaccine itself.
* Tell your doctor that you want the hepatitis B vaccine and HBiG to be given to your baby in the delivery room. This request is to make certain the doctor or nurse doesn't forget to give your new baby the two drugs right after delivery. Ask your partner or husband to make sure that these drugs are given since you may be too tired to ask.
Why should my baby be vaccinated in the delivery room?
To protect your baby from a chronic infection, the vaccine must be given within the FIRST 12 HOURS OF LIFE. This is a very small window of opportunity. You don't get a second chance! If the vaccine is given within the first 12 hours of life, then your baby has a greater than 95% chance of being protected from the hepatitis B virus. If the vaccine is not given correctly, then your baby will most likely become chronically infected with hepatitis B for a lifetime.
