Vaccinations and Screenings During Pregnancy

pregnancy scans and screenings

Key Points

One of the most critical aspects of pregnancy is ensuring the health and well-being of both the expectant mother and the developing baby. Central to this is the role of vaccinations, scans, and screenings, which are pivotal in prenatal care.

In this guide, we explore the essential vaccinations and screenings recommended during pregnancy. These medical interventions are carefully selected to protect both mother and child from various health risks. Vaccinations safeguard against diseases that can be more severe during pregnancy, while screenings provide vital insights into the baby’s development and the mother’s health.

Understanding the significance, timing, and safety of these procedures is crucial. This knowledge not only prepares you for what to expect but also eases any concerns you might have. Our aim is to provide clear, trustworthy information to empower you to make informed decisions for you and your baby’s health.

The Importance of Vaccinations During Pregnancy:

Vaccinations during pregnancy are pivotal not only for safeguarding the health of the mother but also for providing essential immunity to the unborn child.
Key vaccines, such as the flu shot and Tdap (tetanus, diphtheria, and pertussis), are routinely recommended for all pregnant women. These vaccines are critical in protecting against illnesses that can be particularly severe during pregnancy and in conferring early immunity to the newborn.

  • Flu Vaccine: Influenza, commonly known as the flu, poses a higher risk for pregnant women, potentially leading to serious complications like pneumonia and preterm labor. The flu vaccine, deemed safe at any stage of pregnancy, is a crucial measure to protect both the mother and the baby. The antibodies developed in response to the vaccine not only protect the mother but also pass through the placenta, providing the baby with early protection that lasts for several months after birth.
  • Tdap Vaccine: Pertussis, or whooping cough, is a respiratory infection that can be life-threatening for newborns. The Tdap vaccine, administered during the third trimester, typically between 27 and 36 weeks of gestation, is vital for protecting the baby against this illness. This timing is strategically chosen to maximize the transfer of antibodies from mother to baby, ensuring that the newborn has immediate protection until they are old enough to be vaccinated themselves. This vaccine also helps protect the mother from contracting whooping cough and passing it to her newborn.
  • Hepatitis B Vaccine: If a pregnant woman is at high risk for hepatitis B or has been tested and found to be hepatitis B surface antigen-positive, the hepatitis B vaccine is recommended. This vaccine can prevent transmission of hepatitis B to the baby, which can lead to serious health issues.
  • MMR (Measles, Mumps, and Rubella) Vaccine: While this vaccine is typically not administered during pregnancy, it’s important for women to have immunity to these diseases before becoming pregnant. If a woman is not immune, the MMR vaccine may be recommended before pregnancy or immediately postpartum.
  • Varicella Vaccine: Like the MMR, the varicella vaccine, which protects against chickenpox, is not given during pregnancy. However, it’s recommended for women who do not have immunity to chickenpox to receive this vaccine before pregnancy.

These vaccinations are a key part of prenatal care and are carefully timed to offer the best protection to both the mother and the baby. It’s important for expectant mothers to discuss their vaccination schedule with their healthcare provider to ensure they are up-to-date and to understand the best timing for each vaccine.

Antenatal Tests and Screenings for a Healthy Pregnancy:

Pregnancy is a time of significant changes and medical screenings play a vital role in ensuring the health of both mother and baby.

Routine Check-Ups:
Regular antenatal appointments are crucial for monitoring any changes and addressing any potential health concerns. At every antenatal visit, expect checks for blood pressure to monitor for pre-eclampsia, urine tests for protein and sugar levels, blood pressure and weight monitoring.

Key Screenings in Early Pregnancy (6-12 Weeks):

  • Ultrasound dating scan: An early ultrasound scan, scheduled between the 6th and 12th week, can provide an accurate estimated delivery date (EDD) and offer the first glimpse of your baby. You will be able to see the baby’s heartbeat during this scan and it is an emotional moment for most expectant parents. This scan will also confirm the baby’s location.
  • Hepatitis B Antigen Screening: Hepatitis B is a liver virus. It’s often asymptomatic and can transmit to newborns during birth. If you test positive, your baby will receive the Hepatitis B vaccine and Immunoglobulin within 12 hours of their birth to prevent infection.
  • Full Blood Count: This test checks for low blood count and thalassemia (a prevalent genetic blood disorder characterized by the formation of abnormal hemoglobin). Low blood counts can result from insufficient iron intake and might require supplementation.
  • Blood grouping, Rh status, and antibody testing: This test is crucial for emergency situations involving bleeding in pregnant women. The test determines blood group, detects antibodies, and assesses the risk of antibody development, especially when the mother is Rh-negative and the father is Rh-positive. Anti-D injections at 28 and 34 weeks, and post-delivery, prevent antibody formation, reducing the risk of hemolytic disease in future babies, which can lead to complications like anemia, heart failure, and jaundice during pregnancy or in newborns.
  • VDRL (Venereal Disease Research Laboratory) Test: Tests for syphilis, which can be passed on to the baby and can cause birth defects.
  • HIV Test: Early detection can reduce the risk of transmission to the baby.
  • German Measles (Rubella) Antibody Screening: Checks immunity to Rubella to protect future pregnancies.

Down Syndrome Screening:

  • Down syndrome screening assesses the risk of a child having an extra chromosome 21. While the likelihood increases with maternal age, it can occur at any age and is usually random. The developmental disorder leads to mild to moderate intellectual delay, heart, hearing, and visual defects. Stimulation programs benefit affected children, some leading healthy lives up to 40-50 years. Previously, invasive tests like amniocentesis were common for those over 35 but detected only 30% of cases. Now, non-invasive screenings offer risk assessments to all mothers. The decision for screening is optional, requiring consideration between spouses for further confirmatory tests.
  • Various tests like Nuchal Translucency (NT) measurement (detection rate of 80%), maternal serum screening (detection rate of 66%), and a combined test that combines both the NT measurement and serum screening (recommended test with detection rate of 90%) are available. These screenings assess the risk of Down syndrome and help in deciding whether further confirmatory tests are needed.
  • Further confirmatory tests used are Chorionic villus sampling (CVS, involving a biopsy of the placenta) and Amniocentesis (entails inserting a needle into the amniotic sac and extracting amniotic fluid for testing). They both carry a small risk of miscarriage (0.5% to 1%)

Mid-Pregnancy Screenings (18-22 Weeks):

  • Detailed Ultrasound Scan (Anomaly Scan): Ensures the baby is growing well and checks for major physical defects. This scan may also reveal the baby’s gender.
  • Oral Glucose Tolerance Test (OGTT): Is usually carried out between 24-28 weeks to test for gestational diabetes. It requires fasting overnight and comprises 3 blood tests. Each test is carried out an hour apart from the preceding one – starting with the first one in the morning followed by a glucose drink. 

Third Trimester Screenings:

  • Regular and Doppler Ultrasound Scans: Regular ultrasound scans are used to monitor the growth of the foetus. Doppler scans are used to monitor the flow in blood vessels supplying blood to the foetus.
  • Group B Streptococcus Test (GBS): GBS screening is not part of the routine but is recommended. The test requires a vaginal swab. If GBS is detected then it could affect the baby. Antibiotics are administered during labour and birth if GBS is positive.  
  • Cardiotocograph (CTG): Used to monitor the contractions and the fetal heartbeat during labour.

It’s important to remember that regular consultations with your healthcare provider and attending all prenatal appointments are essential for a healthy pregnancy.

  • Typically, two doses of the tetanus toxoid (TT) vaccine are given during pregnancy, spaced 4 weeks apart.

The Tdap vaccine is often administered in the 7th month to protect against whooping cough.

No specific injection is routinely given in the 3rd month; vaccinations depend on individual health assessments.

At 28 weeks, the Tdap vaccine is recommended to protect the baby from whooping cough after birth.
