A molecular assembly system that renders antigens of choice highly repetitive for induction of protective B cell responses.

2002

Virus like particles (VLPs) are known to induce potent B cell responses in the absence of adjuvants. Moreover, epitope-specific antibody responses may be induced by VLPs that contain peptides inserted in their immunodominant regions. However, due to steric problems, the size of the peptides capable of being incorporated into VLPs while still permitting capsid assembly, is rather limited. While peptides genetically fused to either the N- or C-terminus of VLPs present fewer assembly problems, the immune responses obtained against such epitopes are often limited, most likely because the epitopes are not optimally exposed. In addition, such particles may be less stable in vivo. Here, we show th…

Annual influenza vaccination is recommended for healthcare workers, but many do not follow the recommendation. The objective of this study was to investigate the factors associated with seasonal influenza vaccination in the 2011–2012 season. We carried out an anonymous web survey of Spanish primary healthcare workers in 2012. Information on vaccination, and knowledge and attitudes about the influenza vaccine was collected. Workers with medical conditions that contraindicated vaccination and those with high risk conditions were excluded. Multivariate analysis was performed using unconditional logistic regression. We included 1,749 workers. The overall vaccination coverage was 50.7% and was h…

Time trends of human papillomavirus types in invasive cervical cancer, from 1940 to 2007.

2013

Contribution over time of human papillomavirus (HPV) types in human cancers has been poorly documented. Such data is fundamental to measure current HPV vaccines impact in the years to come. We estimated the HPV type-specific distribution in a large international series of invasive cervical cancer (ICC) over 70 years prior to vaccination. Paraffin embedded ICC cases diagnosed between 1940 and 2007 were retrieved from eleven countries in Central-South America, Asia and Europe. Included countries reported to have low-medium cervical cancer screening uptake. Information on age at and year of diagnosis was collected from medical records. After histological confirmation, HPV DNA detection was per…

One-year breakthrough SARS-CoV-2 infection and correlates of protection in fully vaccinated hematological patients

2023

AbstractThe long-term clinical efficacy of SARS-CoV-2 vaccines according to antibody response in immunosuppressed patients such as hematological patients has been little explored. A prospective multicenter registry-based cohort study conducted from December 2020 to July 2022 by the Spanish Transplant and Cell Therapy group, was used to analyze the relationship of antibody response over time after full vaccination (at 3–6 weeks, 3, 6 and 12 months) (2 doses) and of booster doses with breakthrough SARS-CoV-2 infection in 1551 patients with hematological disorders. At a median follow-up of 388 days after complete immunization, 266 out of 1551 (17%) developed breakthrough SARS-CoV-2 infection a…

CIMT 2019: report on the 17th Annual Meeting of the Association for Cancer Immunotherapy

2019

The 17th Annual Meeting of the Association for Cancer Immunotherapy (CIMT), Europe`s cancer immunotherapy meeting, took place in Mainz, Germany from 21 to 23 May, 2019. Recent advancements in cance...

SARS‐CoV ‐2‐reactive antibody detection after SARS‐CoV ‐2 vaccination in hematopoietic stem cell transplant recipients: Prospective survey from the S…

2021

This is a multicenter prospective observational study which included a large cohort (n = 397) of allogeneic (allo-HSCT) (n = 311) and autologous (ASCT) hematopoietic stem cell transplant (n = 86) recipients who were monitored for antibody detection within 3 to 6 weeks after complete SARS-CoV-2 vaccination from February 1st 2021 to July 20th 2021. Most patients (n = 387, 97.4%) received mRNA-based vaccines. Most of recipients (93%) were vaccinated more than 1 year after transplant. Detectable SARS-CoV-2-reactive antibodies were observed in 242 (78%) of allo-HSCT and in 73 (85%) of ASCT recipients. Multivariate analysis in allo-HSCT recipients identified lymphopenia <1x109 /mL [Odds ratio (OR…

Systematic review and meta-analysis of determinants associated with HPV vaccination uptake in Europe

2020

Abstract Background Human papillomavirus (HPV) vaccines are the most important strategy to prevent HPV-related cancers and benign lesions. However, low immunization levels observed in several countries requires a deeper analysis of determinants associated with HPV vaccination uptake. Aim of the research is to identify the main determinants associated with HPV vaccination uptake among European adolescents, through a systematic literature review and meta-analysis. Methods The research was conducted on electronic databases including PubMed/MEDLINE and SCOPUS, identifying 1147 studies. Original articles published between 2000 and 2018 were retrieved, with restriction criteria applied to the Eur…

BCR-ABL Derived Peptide Vaccine in Chronic Myeloid Leukemia Patients with Molecular Minimal Residual Disease During Imatinib: Interim Analysis of a P…

2009

Abstract Abstract 648 Introduction: Imatinib (IM) 400mg daily is the standard treatment for chronic myeloid leukemia (CML) patients and a complete cytogenetic response (CCyR) is achieved in the majority of patients within one year of treatment. In addition, a considerable number of patients reach a major molecular response (i.e BCR-ABL/ABL ratio &lt;0.1%) but BCR-ABL transcript is still measurable in most of treated patients revealing the persistence of a minimal residual disease (MRD). In a previous small pilot study, vaccinations with p210 b3a2-derived fusion peptides in IM treated CML patients appeared to induce both a peptide specific immune response and a reduction of residual disease …

Pandemia e vaccinazione dei lavoratori nello scenario comparato

2022

The essay analyses Covid-19 workers’ vaccinations in the Italian, Spanish, French, and US legal frameworks. By using the function of cultural orientation of comparative method, the work highlights that in Southern-Europe workers’ vaccination may be mandated by the legislator with the aim to promote collective health. By the contrary the US system, centred on the freedom of economic initiative, allows employer-mandated vaccinations in lack of specific legislation. Il saggio analizza in chiave comparata la vaccinazione del lavoratore contro il virus Sars-Covid 19 negli ordinamenti italiano, spagnolo, francese e statunitense. Nel privilegiare la funzione di orientamento culturale della compara…
