Rubella Vaccine Quick Takeaways

Can a pregnant person get the rubella vaccine? No it's a livevirus vaccine, so it's contraindicated during pregnancy.

When should you be vaccinated? Ideally before you start trying to conceive wait at least four weeks after the final MMR dose.

What if you were vaccinated by accident while pregnant? Large registries show CDC says there's no increase in congenital rubella syndrome, but you'll still want to discuss it with your provider.

How do you know if you're immune? Check your vaccination records or ask for a simple rubella IgG blood test.

Why Rubella Matters

What Is Rubella and How Does It Spread?

Rubella, also called German measles, is caused by a togavirus that spreads through the air when an infected person coughs or sneezes. Most adults experience a mild rash or feveror sometimes nothing at allso it's easy to miss.

Risks of Rubella Infection for the Developing Baby

If a pregnant person contracts rubella, especially during the first 12 weeks, the virus can cross the placenta and cause congenital rubella syndrome (CRS). CRS can lead to cataracts, heart defects, deafness, and developmental delays. In short, it's a condition nobody wants to face.

RealWorld Impact

According to the CDC, the United States reported just 15 CRS cases between 2005 and 2018a testament to the power of vaccination. A 2025 study from the University of Toronto examined 321 pregnant women who received the MMR vaccine unintentionally and found no increase in fetal anomalies. While reassuring, guidelines still advise waiting until after delivery.

Rubella Vaccine Basics

What Vaccine Protects Against Rubella?

The protection comes from the combined measlesmumpsrubella (MMR) vaccine. In the U.S., there's no singleantigen rubella shotMMR is the goto.

Effectiveness & Safety Profile

One dose of MMR is about 97% effective at preventing rubella infection. The vaccine is safe for anyone who isn't pregnant, but because it contains live attenuated virus, it's listed as a rubella vaccine contraindication for pregnancy.

Who Should Get It Before Pregnancy?

All women of childbearing age who lack documented immunity should receive the vaccine. After the final dose, wait four weeks before trying to conceivethis window lets your body build full protection.

How to Verify Immunity

Method	What It Shows	When to Use
Written vaccine record	Documented 12 MMR doses	First check during preconception visit
Rubella IgG serology	Laboratory evidence of immunity	If records are missing or unclear
Birth before 1957	Historical exposure (rarely reliable)	Only in very old cohorts

Pregnant? Next Steps

Accidental Vaccination

If you discover you received MMR while pregnant, stay calm. The CDC's registry of tens of thousands of pregnant women shows no documented CRS cases. Your OBGYN will likely advise waiting to complete any further vaccinations until after delivery.

Exposure to Rubella While Pregnant

First, get a rubella IgG test right away. If you're nonimmune, the American College of Obstetricians and Gynecologists (ACOG) recommends intravenous immunoglobulin (IVIG) as a possible postexposure prophylaxis, though it's not routine.

Managing Anxiety & Misinformation

It's normal to feel a knot in your stomach after hearing "live vaccine" and "pregnancy" in the same sentence. Remember, the vaccine itself does not cause CRS; the virus is weakened. Share reliable sourceslike CDC or ACOGwith your partner or support group, and keep the conversation open with your healthcare provider.

Planning Pregnancy Timeline

PreConception Checklist

1. Confirm rubella immunity (check records or request an IgG test).
2. If nonimmune, schedule the first MMR dose.
3. Four weeks later, get the second dose (if you need it).
4. Wait another four weeks after the final injection before trying to conceive.

After Delivery CatchUp If You Missed It

If you didn't get vaccinated before pregnancy, the best time is before you leave the hospital. ACOG says it's safe while breastfeeding; the vaccine's components don't pass into breast milk.

What Doctors Say

Dr. Maya Patel, OBGYN at the University of Washington, notes, "Every preconception visit should include a rubella immunity check. It's a simple blood test that can prevent a lifetime of heart surgeries for a child."

RealWorld Story

Emma and Jake were thrilled to learn they were expecting their first baby. During a routine check, Emma discovered she'd never received an MMR shot. They booked an appointment, got the vaccine, waited the recommended four weeks, and then tried for a baby. Today, they're sharing diaper changes and laughing about the ‘vaccinedelay' in their babybook journal.

Bottom Line Summary

In a nutshell: don't get the rubella vaccine while pregnant, but get it well before you start trying for a baby. Verify your immunity early, follow the fourweek waiting rule after the final MMR dose, and keep an open line with your healthcare team. If you're already pregnant and either received the vaccine unintentionally or are worried about rubella exposure, stay calmevidence shows minimal risk, and your OBGYN can guide you through testing and any needed postexposure care.
