AI Article Synopsis
Article Abstract
Background: Assessing the prevalence of infections, which are preventable by vaccination, is crucial to monitor the vaccination program efficacy, and it can demonstrate the gaps in population immunity. The current study attempted to assess the specific Immunoglobulin (IgG) antibody against measles, mumps, and rubella (MMR) in Iranian children and adolescents, years after their vaccination.
Methods: This cross-sectional study was conducted in Iran. Serum samples of 2100 students, aged 7-18 years, included in a national health survey, were tested for MMR antibodies by ELISA assay. Multistage random cluster sampling was used to select subjects from 30 provinces in Iran.
Results: Overall, 1871, 1718, and 1678 serums were tested for measles, mumps, and rubella antibodies, respectively. The prevalence of positive test was 1231 (65.8%) for measles, 1327 (77.2%) for mumps and 1344 (80.1%) for rubella.
Conclusion: Despite high vaccination coverage in Iran, IgG antibody against measles, mumps, and rubella was not detected in a considerable proportion of children and adolescents aged 7-18 years. In case of contacts with residents of other countries, where measles or rubella have not yet been eliminated, it may create problems for Iranian children.

To determine the association between parental characteristics and MMR (measles-mumps- rubella) vaccination status of children in the United States. We conducted a cross-sectional study from July 2023 to April 2024 using a digital health survey via OutbreaksNearMe, weighted to target national population characteristics. We analyzed the responses of 19 892 parents of children younger than 5 years to examine the association between self-reported parental characteristics (i.

The mpox virus (MPXV) came to global attention with the 2022 global outbreak. Current vaccination and post-exposure prophylaxis against MPXV consists of live vaccinia whole virus-based vaccines including ACAM2000®, JYNNEOS™, and LC16m8 originally developed against smallpox. Here, we analyzed 152 vaccinia-derived peptides we identified by mass spectrometry for homology with MPXV-1 and MPXV-2 sequences to evaluate their potential relevance to MPXV-specific immunity.

Description: The aim of this American Gastroenterological Association (AGA) Clinical Practice Update (CPU) is to provide best practice advice (BPA) statements for gastroenterologists and other health care providers who provide care to patients with inflammatory bowel disease (IBD). The focus is on IBD-specific screenings (excluding colorectal cancer screening, which is discussed separately) and vaccinations. We provide guidance to ensure that patients are up to date with the disease-specific cancer screenings, vaccinations, as well as advice for mental health and general wellbeing.
