OBJECTIVE To assess the vaccination history and the status of vaccine-induced protection from measles and rubella in children after treatment for acute lymphoblastic leukemia. METHODS Measles and rubella immunological status was assessed by the ELISA technique for 22 children previously treated for acute lymphoblastic leukemia. RESULTS From the total of 22 patients, 20 had been given two do...
Combined measles, mumps, and rubella vaccination is soon to become available in Britain in the routine immunisation programme. A controlled study was performed in 319 children, aged 13 months, to assess the antibody response and clinical reactions to a new combined measles, mumps, and rubella vaccine in comparison with a single component measles vaccine. In the children who received the combine...
The interference of IgM-class rheumatoid factor (RF) in the solid-phase radioimmunoassay (RIA) of rubella virus IgM antibodies was studied. Acute rubella infections did not significantly activate RF. False-positive rubella antibody results were obtained, however, when patients with raised RF levels were tested. If a low rubella IgG antibody titre was present, a high level of RF was required to ...
Rubella virus is a member of family Togaviridae that usually causes a mild, self limiting infection in children and adults. The virus is of high public health significance owing to its ability to cause congenital rubella syndrome (CRS), abortion and still births. The clinical spectrum of CRS includes complete or partial blindness, sensorineural hearing defects, mental retardation, psychomotor d...
Objective: This study was undertaken to determine in a cross-sectional survey whether rubella virus circulation in the Indian population induces detectable immunoglobulin G (IgG) antibodies with a protective level, in a random group of pregnant & nonpregnant women. Methods: Rubella-IgG antibody status was assessed in 1182 Indian women comprising of 617 pregnant women, 497 nonpregnant women of c...
BACKGROUND The aim of this study was to assess whether rubella vaccination immediately after delivery could expose seronegative women to specific untoward effects. METHODS 163 rubella-seronegative women received Measles-Mumps-Rubella (MMR) vaccine in the immediate postpartum period; they were evaluated at one month and at three months thereafter through telephone interviews. As controls, we m...
BACKGROUND Despite a safe and effective vaccine, rubella vaccination programs with inadequate coverage can raise the average age of rubella infection; thereby increasing rubella cases among pregnant women and the resulting congenital rubella syndrome (CRS) in their newborns. The vaccination coverage necessary to reduce CRS depends on the birthrate in a country and the reproductive number, R0, a...
OBJECTIVE To determine the knowledge of rubella immune status among practicing obstetrician-gynecologists in the United States and of rubella immunity policies covering healthcare workers in the obstetric-care office setting. DESIGN Mailed survey questionnaire, August through December 1994. SETTING Physicians from multiple-practice sites including private office, public institution, univers...
Rubella virus infection is typically diagnosed by the identification of rubella virus-specific immunoglobulin M (IgM) antibodies in serum, but approximately 50% of serum samples from rubella cases collected on the day of rash onset are negative for rubella virus-specific IgM. The ability to detect IgM in sera and oral fluids was compared with the ability to detect rubella virus RNA in oral flui...
In China, rubella vaccination was introduced into the national immunization program in 2008, and a rubella epidemic occurred in the same year. In order to know whether changes in the genotypic distribution of rubella viruses have occurred in the postvaccination era, we investigate in detail the epidemiological profile of rubella in China and estimate the evolutionary rate, molecular clock phylo...
