Rubella, also known as German measles, is more than just a mild childhood illness. When contracted during pregnancy, it becomes a significant threat to both the mother and the unborn child. The consequences can be severe, including miscarriage, stillbirth, or congenital rubella syndrome (CRS), which causes birth defects such as deafness, heart abnormalities, and developmental delays.
In this blog, we will explore the role of the rubella vaccine in protecting mothers and babies, answer commonly asked questions about its use, and understand why getting vaccinated before pregnancy is critical.
What is rubella, and how does it affect pregnancy?
Rubella is a contagious viral infection that spreads through respiratory droplets when an infected person coughs or sneezes. For most people, rubella symptoms are mild, including fever, rash, and swollen lymph nodes. However, for pregnant women, especially during the first trimester, rubella poses serious risks.
If a pregnant woman contracts rubella, the virus can cross the placenta and infect the developing fetus. This often leads to congenital rubella syndrome (CRS), which may cause:
-
Hearing impairment
-
Heart defects such as patent ductus arteriosus
-
Vision issues, including cataracts
-
Neurological problems like developmental delays and intellectual disabilities
The rubella vaccine, often administered as part of the MMR (Measles-Mumps-Rubella) or MR (Measles-Rubella) vaccine, is a proven way to prevent these devastating outcomes.
Why is rubella vaccination essential for women planning pregnancy?
The rubella vaccine is vital for women planning to conceive because the infection's impact during pregnancy can be catastrophic. Unlike many other vaccines, the rubella vaccine is contraindicated during pregnancy as it is a live attenuated vaccine. Therefore, women must ensure they are immune before becoming pregnant.
Key reasons to get vaccinated before pregnancy:
-
Prevention of Congenital Rubella Syndrome (CRS): Protects the fetus from severe birth defects.
-
Avoidance of Pregnancy Complications: Reduces the risk of miscarriage and stillbirth.
-
Herd Immunity Contribution: Protects those who cannot be vaccinated, like pregnant women who are not immune.
Women who are unsure about their immunity should consult their healthcare provider for a blood test to check for rubella antibodies.
Can you receive the rubella vaccine during pregnancy?
No, the rubella vaccine cannot be administered during pregnancy because it contains a live, weakened virus. While it is generally safe, there is a theoretical risk of transmitting the virus to the fetus.
If a pregnant woman is found to be non-immune, she must wait until after delivery to receive the vaccine. It is also recommended to avoid pregnancy for at least one month after vaccination to ensure safety.
How effective is the rubella vaccine?
The rubella vaccine is highly effective, with studies showing that a single dose provides immunity in over 95% of recipients. In many countries, including India, rubella vaccination has been instrumental in reducing the prevalence of CRS.
The R-Vac Injection, a specific formulation of the rubella vaccine, is commonly used for immunisation. This injection provides effective protection against rubella by stimulating the immune system to produce antibodies. These antibodies remain in the body long-term, ready to fight off the actual virus if exposed.
For women planning to conceive, receiving the injection ensures immunity before pregnancy, safeguarding both maternal and fetal health.
What are the side effects of the rubella vaccine?
The rubella vaccine is safe for most individuals, but mild side effects may occur, including:
-
Pain or redness at the injection site
-
Low-grade fever
-
Mild rash
-
Temporary joint pain, particularly in adult women
Severe allergic reactions are extremely rare. However, individuals with known allergies to vaccine components should discuss their options with a healthcare provider.
What is India doing to combat rubella?
India has taken significant steps to eliminate rubella through vaccination initiatives. In 2017, the government launched a nationwide Measles-Rubella (MR) vaccination campaign, targeting children aged 9 months to 15 years. This campaign aimed to reduce measles and rubella infections, preventing CRS cases across the country.
The inclusion of the rubella vaccine in India’s Universal Immunization Programme (UIP) ensures that the vaccine is accessible to all, contributing to the long-term goal of rubella elimination.
How can women ensure they are protected before pregnancy?
Women can take the following steps to ensure immunity before pregnancy:
-
Get Tested for Immunity: A blood test can confirm the presence of rubella antibodies.
-
Receive the Vaccine if Needed: If you are not immune, get vaccinated at least one month before trying to conceive.
-
Maintain a Vaccination Record: Keeping a record ensures that you don’t miss important immunisations.
What happens if I contract rubella during pregnancy?
If a pregnant woman contracts rubella, especially in the first trimester, it’s critical to seek immediate medical attention. The healthcare provider may recommend monitoring the pregnancy closely for signs of complications or fetal abnormalities.
In some cases, antiviral medications may be considered, but prevention through vaccination remains the best approach.
Is it safe to vaccinate children to protect pregnant mothers?
Yes, vaccinating children plays a crucial role in protecting pregnant women. By reducing the overall circulation of the rubella virus in the community, child vaccination contributes to herd immunity, minimising the risk of exposure for pregnant women who may not be immune.
What myths exist around the rubella vaccine?
There are several misconceptions about the rubella vaccine. Let’s debunk some of the common myths:
-
Myth: The vaccine causes infertility.
Fact: There is no evidence linking the rubella vaccine to infertility. -
Myth: The vaccine is unsafe for women planning pregnancy.
Fact: The vaccine is safe and recommended for women before conception. -
Myth: Rubella is not a serious disease.
Fact: While mild in most cases, rubella during pregnancy can lead to severe complications, making vaccination essential.
Real-life impact: Stories of prevention
One mother, Priya, shared her experience: “I didn’t know I wasn’t immune to rubella until I consulted my doctor while planning my second pregnancy. I got the vaccine and waited a month before trying to conceive. Today, I’m grateful that I took this precaution because it gave me peace of mind throughout my pregnancy.”
Such stories highlight the importance of being proactive about rubella vaccination.
Safeguarding Future Generations
The rubella vaccine is a powerful tool in preventing serious complications during pregnancy. For women planning to conceive, ensuring immunity through vaccination is a simple yet effective step in safeguarding maternal and fetal health. Programs like India’s Universal Immunization Programme and campaigns targeting rubella elimination are pivotal in reducing the burden of this disease.
If you are considering pregnancy or unsure about your immunity, consult your healthcare provider today. By taking proactive steps, you can protect yourself, your baby, and future generations from the risks associated with rubella.
