Most women think they no longer need vaccination against German Measles (Rubella) since they most likely were vaccinated against it when they were young. Bad news is even if you were vaccinated at school, studies show that immunity against the virus may not last as long as previously thought. The effects of the vaccines can wear off over a long period of time.
For this reason, most women of child bearing age should double check their immunity against German Measles before getting pregnant. If the rubella immunity test shows that you are not immune to the virus, better have yourself vaccinated at least a month before trying to get pregnant. You cannot and should not have the rubella vaccine while pregnant since the vaccine contains a live virus which could cause rubella infection to your baby.
German measles or Rubella can cause stillbirth, miscarriage or birth defects (congenital rubella syndrome) such as hearing loss, brain damage, hear defects and cataracts for your unborn baby specially if you catch it during the first 4 months (16 weeks) of pregnancy.
