INTRODUCTION Because of variability in published A(H1N1)pdm09 influenza vaccine effectiveness estimates, we conducted a study in the adults belonging to the risk groups to assess the A(H1N1)pdm09 MF59-adjuvanted influenza vaccine effectiveness. METHODS VE against influenza and/or pneumonia was assessed in the cohort study (n>25000), and vaccine effectiveness against laboratory-confirmed A(H1N...

Emulsions have been used to boost immunogenicity of antigens since the discovery of complete Freunds adjuvant. Optimization to reduce reactogenicity of emulsion adjuvants lead to the development of oil in water emulsions based on squalene. MF59 is an oil-in-water emulsion that is a component of an approved influenza product in Europe. Currently MF59 is manufactured from squalene derived from an...

AIM Adjuvanted influenza vaccines can overcome the poor antibody response of conventional non-adjuvanted vaccines in the elderly. We evaluated the immunogenicity, safety and clinical effectiveness of an MF59(®)-adjuvanted trivalent influenza vaccine (aTIV) compared with a non-adjuvanted vaccine (TIV) in subjects ≥65 years old, with or without co-morbidities. METHODS In 2010-2011, subjects (N=...

BACKGROUND An effective vaccine is urgently needed against the H7N9 avian influenza virus. We evaluated the immunogenicity and protective efficacy of a split-virion H7N9 vaccine with or without the oil-in-water adjuvants in ferrets. METHODS Ferrets were vaccinated with 2 doses of unadjuvanted, MF59 or AS03-adjuvanted A/Shanghai/2/2013 (H7N9) vaccine, and the induction of antibodies to hemaggl...

Although the initial isolates of the severe acute respiratory syndrome (SARS) coronavirus (CoV) are sensitive to neutralization by antibodies through their spike (S) glycoprotein, variants of S have since been identified that are resistant to such inhibition. Optimal vaccine strategies would therefore make use of additional determinants of immune recognition, either through cellular or expanded...

RV144 correlates of risk analysis showed that IgG antibodies to gp70V1V2 scaffolds inversely correlated with risk of HIV acquisition. We investigated IgG antibody responses in RV135 and RV132, two ALVAC-HIV prime-boost vaccine trials conducted in Thailand prior to RV144. Both trials used ALVAC-HIV (vCP1521) at 0, 1, 3, and 6 months and HIV-1 gp120MNgD and gp120A244gD in alum (RV135) or gp120SF2...

OBJECTIVE To assess the risk of adverse perinatal events of vaccination of pregnant women with an MF59 adjuvanted vaccine. DESIGN Cross sectional multicentre study. SETTING 49 public hospitals in major cities in Argentina, from September 2010 to May 2011. PARTICIPANTS 30,448 mothers (7293 vaccinated) and their 30,769 newborns. MAIN OUTCOME MEASURE Primary composite outcome of low birth ...

BACKGROUND The present study was a prospective observational study to evaluate the safety profile of Celtura(®), a monovalent, cell culture-derived, inactivated subunit influenza vaccine prepared from A/California/07/2009(H1N1) with the adjuvant MF59(®). Subjects were enrolled prospectively during the H1N1 2009 influenza pandemic at medical centres in Colombia, Chile, Switzerland, and Germany d...

The first large-scale outbreaks of respiratory disease in the 21st century were caused by the influenza A (H1N1) virus in 2009, which affected mostly young adults. The M59 vaccine was developed to control pandemic influenza A (H1N1). However, the complications arising from the use of the non-adjuvanted and adjuvanted vaccines in young male Korean soldiers have not previously been evaluated ...

Vaccines are critical in the fight against infectious diseases, and immune-stimulating adjuvants are essential for enhancing vaccine efficacy. However, the precise mechanisms of action of most adjuvants are unknown. There is an urgent need for customized and adjuvant formulated vaccines against immune evading pathogens that remain a risk today. Understanding the specific role of various cell ty...
