Seroepidemiology of hepatitis A and B and vaccination status in staff at German schools for the handicapped

2016

This study aims to assess serostatus and vaccination status of hepatitis A and B among staff at schools for the handicapped. We also wanted to investigate factors associated with serostatus, number of infections with hepatitis A/hepatitis B at work, and factors influencing being vaccinated or not. The cross-sectional study was carried out between August 2010 and August 2012 at 13 German schools for severely handicapped. Data were analyzed using blood samples, vaccination documents, and questionnaires. A total of 395 persons participated in our study (response: 59.7%), information on 367 could be used for analysis. Two respondents have been infected with HAV at work, 53.4% were anti-HAV sero…

A Controlled Trial of Two Acellular Vaccines and One Whole-Cell Vaccine against Pertussis

1996

Background Concern about both safety and efficacy has made the use of whole-cell pertussis vaccines controversial. In some European countries, including Italy, the rate of vaccination against pertussis is low. Methods We conducted a double-blind trial in Italy in which infants were randomly assigned to vaccination at two, four, and six months of age with an acellular pertussis vaccine together with diphtheria and tetanus toxoids (DTP); a DTP vaccine containing whole-cell pertussis (manufactured by Connaught Laboratories); or diphtheria and tetanus toxoids without pertussis (DT). The acellular DTP vaccine was either one containing filamentous hemagglutinin, pertactin, and pertussis toxin ina…

Evolution of the Regulatory Landscape for Immunomodulatory Compounds and Personalized Therapeutic Cancer Vaccines

2014

The term cancer immunotherapy covers a huge range of different therapeutic interventions based on highly diverse medicinal products. Some immunotherapy products such as monoclonal antibodies have successfully been developed during the last years and contributed to major advances in cancer therapy. Development of cancer vaccines seemed to be more challenging. Nevertheless, some promising candidates are currently in late-stage clinical development, and one product (sipuleucel-T) was recently approved in the United States (USA) and in the European Union (EU). Additionally, cell therapy approaches based on adoptive lymphocyte transfer have recently come into focus due to surprisingly efficient …

Vaccination Status and Attitudes towards Vaccines in a Cohort of Patients with Celiac Disease.

2022

(1) Background: The identification of vaccination status and attitudes towards vaccines among celiac disease (CD) patients is of great importance, but it has not yet been investigated. The aim of this study was to investigate coverage against vaccine-preventable diseases (VPDs), attitudes towards vaccinations, and its determinants among CD patients. (2) Methods: An anonymous web-based validated questionnaire was sent to a mailing list of CD adult patients. Patients were asked to self-report their previous vaccinations and attitudes towards vaccinations, which were defined as positive, negative, and partially positive/negative. The influencing factors towards vaccinations were investigated, …

Vaccine Hesitancy on Social Media: Sentiment Analysis from June 2011 to April 2019

2021

Vaccine hesitancy was one of the ten major threats to global health in 2019, according to the World Health Organisation. Nowadays, social media has an important role in the spread of information, misinformation, and disinformation about vaccines. Monitoring vaccine-related conversations on social media could help us to identify the factors that contribute to vaccine confidence in each historical period and geographical area. We used a hybrid approach to perform an opinion-mining analysis on 1,499,227 vaccine-related tweets published on Twitter from 1st June 2011 to 30th April 2019. Our algorithm classified 69.36% of the tweets as neutral, 21.78% as positive, and 8.86% as negative. The perce…

Evaluation of menstrual irregularities after COVID-19 vaccination: Results of the MECOVAC survey

2022

Abstract We investigated menstrual irregularities after the first and second doses of the COVID-19 vaccine. Women answered a customised online questionnaire (ClinicalTrial.gov ID: NCT05083065) aimed to assess the vaccine type, the phase of the menstrual cycle during which the vaccine was administered, the occurrence of menstrual irregularities after the first and second doses, and how long this effect lasted. We excluded women with gynaecological and non-gynaecological diseases, undergoing hormonal and non-hormonal treatments, in perimenopause or menopause, as well as those who had irregular menstrual cycles in the last 12 months before vaccine administration. According to our data analysis…

Synthesis of a MUC1-glycopeptide-BSA conjugate vaccine bearing the 3'-deoxy-3'-fluoro-Thomsen-Friedenreich antigen.

2011

A novel MUC1-glycopeptide–BSA conjugate vaccine with a specifically fluorinated Thomsen–Friedenreich antigen side chain at Thr6 was prepared. Preliminary immunological experiments reveal specific binding of the tumor-associated glycopeptide antigen analog by anti-MUC1-mouse antibodies.

Pandemic and seasonal influenza viruses cause considerable morbidity and mortality in the general human population. Protection from severe disease may result from vaccines that activate antigen-presenting DC for effective stimulation of influenza-specific memory T cells. Special attention is paid to vaccine-induced CD8+ T-cell responses, because they are mainly directed against conserved internal influenza proteins thereby presumably mediating cross-protection against circulating seasonal as well as emerging pandemic virus strains. Our study showed that influenza whole virus vaccines of major seasonal A and B strains activated DC more efficiently than those of pandemic swine-origin H1N1 and…
