Measles antibodies
Hello Doctor: I was tested for rubella antibodies in 2000, and now that I want to become pregnant, I consulted a doctor about whether I need to be tested again to check if I still have the antibodies.
However, the doctor told me that rubella antibodies provide lifelong immunity and that I do not need to be retested.
According to my research on rubella vaccination, the antibodies last only about ten to fifteen years (I remember receiving this vaccine in the third year of middle school), so I am a bit confused by the doctor's response.
Could you please clarify this for me? Thank you.

When considering pregnancy, understanding your immunity to German measles (rubella) is crucial. Rubella is a viral infection that can have severe consequences for a developing fetus, particularly if the mother contracts the virus during the first trimester. The potential risks include congenital rubella syndrome, which can lead to serious birth defects, including heart problems, hearing impairments, and developmental delays.
Regarding your question about whether you need to test for rubella antibodies before pregnancy, the answer is nuanced. While it is true that many individuals who have been vaccinated against rubella or who have had the disease develop long-lasting immunity, this immunity is not always guaranteed to last a lifetime. Studies suggest that while a significant number of people maintain protective antibody levels for many years, some may experience a decline in immunity over time, particularly if their vaccination occurred many years ago.
The Centers for Disease Control and Prevention (CDC) recommends that women of childbearing age check their rubella immunity status before becoming pregnant. This is typically done through a simple blood test that measures the level of rubella antibodies in the blood. If the test shows that you are not immune, you can receive the rubella vaccine, but it is important to note that the vaccine should not be given during pregnancy. Women are advised to wait at least one month after vaccination before trying to conceive.
In your case, since you were tested for rubella antibodies in the past and are now considering pregnancy, it would be prudent to have your immunity re-evaluated. The fact that you received the vaccine in middle school does not guarantee that your immunity is still intact, especially if it has been many years since your last vaccination or exposure to the virus.
If you find that you are not immune, receiving the vaccine before pregnancy is the best course of action. However, if you are already pregnant, the focus should shift to avoiding exposure to the virus. This can be achieved by minimizing contact with individuals who are infected, especially in public places where outbreaks may occur.
In summary, while some individuals may have lifelong immunity to rubella, it is not a certainty for everyone, especially if the last vaccination was many years ago. Testing for rubella antibodies is a simple and effective way to ensure that you are protected before embarking on your pregnancy journey. If you have any concerns or questions about your specific situation, it is always best to consult with your healthcare provider for personalized advice and recommendations.
