Background and Aims: Rubella virus is a human pathogen that causes congenital rubella syndrome (CRS) when infection occurs during early pregnancy. Vaccination programs have been remarkably successful in controlling natural rubella infection and CRS. Moreover, ongoing surveillance for all cases of rubella and CRS is a vital component of a prevention program. Although the WHO recommends the use o...

Introduction & Objective: Rubella is a disease caused by the rubella virus and is usually mild and self-limiting. Infection of a developing fetus is serious and important because the child may be born with congenital rubella syndrome. Its symptoms include mental retardation, heart defects, cataract, etc. In 2003, mass vaccination against measles and rubella in individuals 5-25 years old was d...
Background & Aim: Rubella vaccine contains live attenuated virus that can be transmitted to fetus causing severe abnormalities in the fetus during pregnancy. However there isn't enough studies to show any congenital rubella syndrome(CRS) in these cases, yet. During mass campaign for Measles-Rubella vaccination in December 2003 in Iran, many pregnant women were vaccinated accidently. In this...
Background and Aims: Rubella is predominantly a childhood disease that is endemic throughout the world and when rubella outbreaks occur, they are accompanied by birth defects following congenital rubella syndrome. Immunity to rubella virus as a teratogenic agent has an important role for prevention of these serious congenital defects. Lymphocyte proliferation assay is a way for investigation of...
Background and Aim: Rubella virus is a potent teratogen. Risk of rubella virus induced multisystem fetal malformation is highly dependent on the gestational age at the time of infection. Because the rubella vaccine is an attenuated live virus, its use is contraindicated during pregnancy. Our objective was to examine whether exposure to rubella vaccine during 1-4 weeks periconceptional period c...

background: potency test for control of rubella vaccine is a significant factor to qualify production line and vaccination program. for this reason, who recommends to use the microtitration method by both vaccine companies and control laboratories. then the study was done to improve this test. methods: three rubella virus samples, including an in-house standard, a lot of vaccine and an in- pr...
the effeminacy of three rubella vaccines, hpv/77 ide-5, cendehill-51 and wistar ra/27/3 in conferring immunity against untenanted rubella virus was compared. vaccination resulted in 90-100 percent protection against clinical rubella. intranasal challenge with the untenanted strain of rubella virus resulted in serologic evidence of in apparent reinfection in three of the ten cendehill-51 vaccine...
In 1985 a patient was described whose persistent polyarthritis was found to be aetiologically linked to rubella virus infection through the detection of repeated maximal synovial lymphocyte proliferative responses to rubella virus antigen and by isolation of rubella virus from her synovium. Follow up over the succeeding seven years has shown continuing chronic polyarthritis and persistent synov...
