Objective: To assess the seroprevalence of immunity to the rubella virus in pregnant women in Haiti attending the Obstetrics and Gynecology Department of the State University Hospital, in the capital city of Port-au-Prince, in order to help with the introduction of the rubella vaccine for the population and provide protection for women of reproductive age in the country.
Methods: This cross-sectional study was done between February 2002 and May 2002. A total of 503 pregnant women were tested for rubella-specific immunoglobulin G antibodies, using enzyme immunoassay; 8 of those women were later excluded because they did not know their age, leaving 495 women in the analysis.
Results: Of the 495 participants included in our analysis, 471 of them (95.2%) were seropositive; only 24 of them (4.8%) were seronegative (susceptible). A statistically significant difference (P = 0.02) was found in the rate of seronegativity for rubella virus between the pregnant women living in the Port-au-Prince area (17 of 426 women, or 4.0%) and those living in rural areas (7 of 69 women, or 10.1%). In terms of age, 81 of the 495 (16.4%) women were under 21 years ld.
Conclusions: This study is an important first step in addressing the issue of prevalence of rubella virus infection among Haitian women and in dealing with the still-underrecognized public health problem of congenital rubella syndrome in Haiti. We recommend additional research that uses randomized sampling and includes a significant proportion of women from rural areas of the country.

Measles, a highly contagious respiratory illness caused by the measles virus (MeV), poses significant global and national public health challenges despite advancements in vaccination efforts. Though measles was declared eliminated in the United States in 2000, recent years have seen a resurgence of cases, particularly in under-vaccinated communities. This resurgence is compounded by factors such as vaccine hesitancy, the impact of the COVID-19 pandemic on immunization rates, and international travel introducing new cases from endemic regions.

Background: The presence of intrathecal total IgG production is a hallmark of cerebrospinal fluid (CSF) characteristics in multiple sclerosis (MS). Herein, we systematically analyze how the intensity (instead of mere presence) of intrathecal total IgG production relates to basic CSF parameters in MS.
Methods: We retrospectively assessed clinical routine CSF findings from 390 therapy-naïve relapsing-remitting MS patients diagnosed according to 2017 revised McDonald criteria.
Seronegative Vaccinees May Not Benefit From Multiple Booster Doses of MMR Vaccine in Restoring Immunity.

Despite the availability of a highly efficacious vaccine, a global resurgence of measles infections has occurred, largely due to decreased vaccination coverage and waning immunity following the two-dose vaccination schedule. This study aims to assess the cellular immune response in individuals who did not respond to the two-dose MMR vaccine and evaluate the efficacy and durability of immune responses after booster doses. An observational study was conducted involving 24 individuals who were seronegative for measles years after completing the two-dose MMR vaccine schedule.

Rubella virus (RUBV) is responsible for causing rashes, lymphadenopathy, and fever which are the hallmarks of an acute viral illness called Rubella. For RUBV replication, the non-structural polyprotein p200 must be cleaved by the rubella papain-like protease (RubPro) into the multifunctional proteins p150 and p90. Hence, RubPro is an attractive target for anti-viral drug discovery.

Rubella is listed as a disease that needs to be eliminated worldwide by the World Health Organization. This study aimed to investigate rubella epidemiology and genetic characteristics based on data from 12 years of laboratory-based surveillance (2009-2020) in Tianjin and to provide baseline genotype data for monitoring future rubella control efforts. We collected RV-positive throat swab samples from confirmed rubella cases during 2009-2020 in Tianjin to isolate RV, amplify and sequence target gene fragments, construct phylogenetic trees, and analyze nucleotide homologies.
