Risk of febrile convulsions after MMRV vaccination in comparison to MMR or MMR+V vaccination.

2014

Abstract Background In July 2006, Priorix-Tetra™, a combined measles-mumps-rubella-varicella (MMRV) vaccine, was licensed in Germany. Since a postlicensure study had shown a more than twofold elevated risk of febrile convulsions (FC) after first dose vaccination with the combined MMRV vaccine ProQuad ® compared to separately administered MMR and V vaccines (MMR+V), the Paul-Ehrlich-Institute, the German regulatory agency for vaccine licensing and safety, requested a study investigating the risk of FC for Priorix-Tetra™. Methods We performed a matched cohort study based on claims data of more than 17 million insurees in the German Pharmacoepidemiological Research Database. All children born …

Impact on rotavirus gastro-enteritis hospitalisation during the first year of universal vaccination in Sicily

2015

Rotavirus (RV) vaccines represents the best strategy for reducing rotavirus gastro-enteritis (RVGE) among children and the introduction of RV vaccination in immunization programmes is strongly recommended by international health authorities.1,2

Asthma and influenza vaccination in elderly hospitalized patients: Matched case-control study in Spain

2017

Influenza infection is an exacerbating factor for asthma, and its prevention is critical in managing asthmatic patients. We investigated the effect of influenza vaccination on asthmatic and non-asthmatic patients hospitalized with laboratory-confirmed influenza in Spain.We made a matched case-control study to assess the frequency of hospitalization for influenza in people aged ≥65 years. Hospitalized patients with unplanned hospital admissions were recruited from 20 hospitals representing seven Spanish regions. Cases were defined as those hospitalized due to a laboratory-confirmed influenza infection and controls were matched by age, sex, and hospital. Data were obtained from clinical recor…

The effectiveness of peer-support for people living with HIV: A systematic review and meta-analysis

2021

Background The practice of involving people living with HIV in the development and provision of healthcare has gained increasing traction. Peer-support for people living with HIV is assistance and encouragement by an individual considered equal, in taking an active role in self-management of their chronic health condition. The objective of this systematic review was to assess the effects of peer-support for people living with HIV. Methods We conducted a systematic review in accordance with international guidelines. Following systematic searches of eight databases until May 2020, two reviewers performed independent screening of studies according to preset inclusion criteria. We conducted ri…

Induction of an Anti-Vaccine Response by T Cell Vaccination in Non-human Primates and Humans

1993

Abstract Experimental and spontaneous autoimmune disease in animals can effectively be prevented and treated by application of pathogenic autoreactive T cells in an attenuated form. This approach has become known as T cell vaccination, T cell vaccination exploits specifically the ability of the immune system to regulate its autoreactive T cells by mechanisms of network control. The success of T cell vaccination in a variety of rodent animal models has raised hopes for its use as an effective and specific therapy in human autoimmune disease. The aim of this study was to induce an anti-T cell response by T cell vaccination in humans and primates as a pre-clinical study into the feasibility an…

Analysis of hospitalizations due to intussusception in Sicily in the pre-rotavirus vaccination era (2003–2012)

2015

Background: Intussusception is the most common cause of bowel obstruction in infants with an incidence ranging from 9-328 cases per 100,000 infants aged 0-11 months. Causes underlining this clinical manifestation are still unknown. Possible relationship with a withdrawn tetravalent rotavirus vaccine was not confirmed by post-licensure studies and actually no increased risk of intussusception was found between infants vaccinated with both the recently licensed rotavirus vaccines. Aim of this study is to analyze the intussusception hospitalizations in Sicily from 2003 to 2012 before the introduction of rotavirus universal vaccination and its possible relation with rotavirus gastroenteritis tr…

Immune response to 13-valent pneumococcal conjugate vaccine with a reduced dosing schedule

2013

Background: The 7-valent pneumococcal conjugate vaccine (PCV7) has demonstrated effectiveness against pneumococcal illnesses when administered as 3 infant doses plus a toddler dose (3+1 schedule) or as an abbreviated schedule of 2 infant doses plus a toddler dose (2+1 schedule). The 13-valent pneumococcal conjugate vaccine (PCV13) is approved and World Health Organization-prequalified for administration in a 2+1 schedule when used as part of routine immunization programs. Objective: To summarize immunologic responses elicited by PCV13 administered in a 2+1 schedule and following 2 doses in a 3+1 schedule. Methods: Studies were double-blind, randomized, active-controlled, multicenter studies…

Vaccination against HPV-Associated Neoplasias

2014

Neoplasias associated with anogenital human papilloma viruses (HPV) are characterised by high patient morbidity and mortality and by appreciable limitations in the patientʼs quality of life. Each year 530,000 women worldwide and 4800 women in Germany develop cervical cancer 1, 2. Biomolecular and epidemiological studies carried out in the past 25 years have demonstrated causal link between persisting infections with HPV 16 and HPV 18 and at least 11 other so-called high-risk HPVs (HR-HPVs) and the development of cervical cancer and its precursor lesions (so-called dysplasias or, respectively, cervical intraepithelial neoplasias – CIN). HPV 16, HPV 18 and other HR-HPVs are also the causes of…

Influence of universal HBV vaccination on chronic HBV infection in Italy: Results of a cross-sectional multicenter study

2017

Background and Aim The universal hepatitis B vaccination for infants and 12-year-old adolescents (the latter limited to the first 12 years of application) was launched in Italy in 1991. Twenty-three years later we evaluated the impact of the vaccination campaign on the burden of HBsAg-positive chronic liver diseases (CLD). Material and Methods 513 HBsAg-positive chronic carriers referring to 16 Italian liver units were investigated and compared with HBsAg carriers enrolled in previous surveys. Results The proportion of inactive carriers decreased from 20.0% in 2001 to 3.3% in 2014, while that of cirrhotic patients increased from 22.6 to 33.2%. Regarding the age class 0–33 (fully covered by …
