Pregnancy brings a flurry of questions about what’s safe for both you and your baby. One common concern is chickenpox. This guide provides clear, reassuring information about chickenpox and pregnancy, including what to do if you’re exposed and how to plan ahead.
Key Facts about Chickenpox and Pregnancy
- Vaccine During Pregnancy: The chickenpox (varicella) vaccine is not recommended during pregnancy.
- Exposure During Pregnancy: Contact your doctor immediately if you’re exposed to chickenpox while pregnant.
- Treatment After Exposure: Varicella-zoster immune globulin (VZIG) may be an option to reduce the severity of the illness.
- Pre-Pregnancy Planning: The best protection is to get vaccinated at least one month before conception.
- Postpartum Vaccination: If you’re not already immune, getting vaccinated after childbirth is safe, even while breastfeeding.
- Confirming Immunity: A simple blood test can determine if you’re immune to chickenpox.
Why the Chickenpox Vaccine Isn’t Recommended During Pregnancy
The chickenpox vaccine contains a weakened, live version of the varicella-zoster virus. While generally safe for most people, it carries a theoretical, albeit low, risk of congenital varicella syndrome (CVS) if given during pregnancy. CVS can cause birth defects in the developing baby. Out of an abundance of caution, doctors advise against receiving the vaccine while pregnant. However, studies of inadvertent vaccination during pregnancy haven’t shown a substantial link to CVS. If you received the vaccine before knowing you were pregnant, talk to your doctor for personalized reassurance.
What to Do If Exposed to Chickenpox During Pregnancy: A Step-by-Step Guide
- Contact Your Healthcare Provider Immediately: Timely intervention is key.
- Provide Exposure Details: Share as much information as possible about the exposure (when, the severity of the other person’s illness, etc.).
- Discuss Immunity and Testing: Your doctor may recommend a blood test to check your immunity status.
- Explore VZIG: If you’re not immune, your doctor can determine if VZIG is appropriate for you. VZIG contains antibodies that can help reduce the severity of chickenpox if given soon after exposure.
- Follow Medical Advice: Adhere to your doctor’s recommendations and attend any follow-up appointments.
Planning for Pregnancy: Pre-Conception Vaccination
The most effective way to protect yourself and your future baby is vaccination at least one month before conception. This allows your body to develop immunity before pregnancy. Talk to your doctor about getting tested for chickenpox immunity if you’re planning a pregnancy.
Chickenpox Symptoms During Pregnancy
Chickenpox typically starts with flu-like symptoms (tiredness, fever, muscle aches). The hallmark itchy rash then appears, developing into small, fluid-filled blisters. Contact your doctor immediately if you experience these symptoms during pregnancy.
Frequently Asked Questions
I was exposed to chickenpox before I knew I was pregnant. What should I do?
Contact your doctor immediately. They can assess the situation and advise on the best course of action, which may include testing for immunity and discussing VZIG.
I think I had chickenpox as a child. Do I still need the vaccine?
A blood test can confirm your immunity. It’s best to be certain, as immunity can wane over time.
What other vaccines should I discuss with my doctor before pregnancy?
Talk to your doctor about recommended pre-pregnancy vaccinations, such as the flu shot and Tdap (tetanus, diphtheria, and pertussis).
Understanding the Risks: Potential Complications
While generally mild in children, chickenpox can pose risks during pregnancy. These include:
- Congenital Varicella Syndrome (CVS): Exposure during the first 20 weeks carries a small risk of CVS, potentially causing birth defects.
- Neonatal Varicella: Exposure shortly before or after birth can lead to serious infection in the newborn.
- Maternal Pneumonia: Pregnant women are more susceptible to developing pneumonia from chickenpox.
Ongoing Research
Research on chickenpox and pregnancy is ongoing. Some studies suggest a longer waiting period between vaccination and conception might be beneficial. Other research focuses on the long-term impacts of chickenpox exposure during pregnancy. Your doctor can provide the latest information and guidance based on the most current research.
