In other cases, a mother's illness may cause congenital malformations; an example is rubella, which can cause heart defects, deafness, developmental delays, and other problems in a fetus if the mother contracts it during pregnancy.
Parents or adults who travel or live abroad with infants less than 12 months old should have evidence of immunity to rubella and mumps, as well as measles, to avoid becoming infected if the infants are exposed to the diseases.
Although rubella causes only mild symptoms in child and adult sufferers, the infection can have severe complications for the fetus of a woman who becomes infected with the virus during the first trimester of pregnancy.
On February 12, the U.S. Court of Federal Claims Office of Special Masters found that the measles, mumps and rubella (MMR) vaccine did not cause autism in Michelle Cedillo, Colton Snyder and William Yates Hazelhurst.
Autism has also been shown to occur more frequently among individuals who have certain medical conditions, including fragile X syndrome, tuberous sclerosis, congenital rubella syndrome, and untreated phenylketonuria.
Women should avoid becoming pregnant for three months after taking rubella vaccine, measles vaccine, mumps vaccine, or the combined measles-mumps-rubella (MMR) as these vaccines may cause problems in the unborn baby.
Rubella, also called German measles or three-day measles, is a highly contagious viral disease that in most children and adults causes mild symptoms of low fever, swollen glands, joint pain, and a fine red rash.
Some prenatal factors known to contribute to growth retardation include a variety of maternal health problems, including toxemia, kidney and heart disease, infections such as rubella and maternal malnutrition.
It is recommended that babies receive a single-dose injection of Varivax between the ages of 12 and 18 months, usually at the same time that they receive their first measles, mumps, and rubella (MMR) vaccine.
