Background and Purpose: Pregnant women are at a higher risk of influenza infection, and influenza vaccination is recommended for these women to reduce the associated complications. This study aimed to determine the knowledge and practice about influenza vaccination and identify the factors influencing compliance with influenza immunization among pregnant women. Methods: This cross-sectional ...
BACKGROUND The A(H1N1)pdm09 virus strain used in the live attenuated influenza vaccine was changed for the 2015-2016 influenza season because of its lack of effectiveness in young children in 2013-2014. The Influenza Vaccine Effectiveness Network evaluated the effect of this change as part of its estimates of influenza vaccine effectiveness in 2015-2016. METHODS We enrolled patients 6 months ...
BACKGROUND Young infants and pregnant women are at increased risk for serious consequences of influenza infection. Inactivated influenza vaccine is recommended for pregnant women but is not licensed for infants younger than 6 months of age. We assessed the clinical effectiveness of inactivated influenza vaccine administered during pregnancy in Bangladesh. METHODS In this randomized study, we ...
OBJECTIVE To estimate the potential cost-effectiveness of quadrivalent influenza vaccine compared with trivalent influenza vaccine in the UK. METHODS A lifetime, multi-cohort, static Markov model was constructed, with nine age groups each divided into healthy and at-risk categories. Influenza A and B were accounted for separately. The model was run in one-year cycles for a lifetime (maximum a...
Background & Objective: DNA vaccines as a new generation of vaccines require adjuvant to improve vaccine immunogenicity; adjuvants can also increase the DNA vaccine efficacy. In this study, the effects of the host’s interferon-inducible Mx protein as bio adjuvant and conventional alum adjuvant were evaluated. Materials & Methods: The BALB/c mice were immunized by different prime-boost strate...
BACKGROUND Many influenza vaccine effectiveness estimates have been made using case-control methods. Although several forms of bias may distort estimates of vaccine effectiveness derived from case-control studies, there have been few attempts to quantify the magnitude of these biases. METHODS We estimated the magnitude of potential biases in influenza vaccine effectiveness values derived from...
BACKGROUND Currently more than 340,000 individuals are receiving long-term hemodialysis (HD) therapy for end-stage renal disease and therefore are particularly vulnerable to influenza, prone to more severe influenza outcomes, and less likely to achieve seroprotection from standard influenza vaccines. Influenza vaccine adjuvants, chemical or biologic compounds added to a vaccine to boost the eli...
Introduction: Influenza virus has several conserved peptides which have the capacity to be used as suitable candidates for appropriate and stable vaccine production against different types of influenza viruses. One of these peptides is HA2, the hemagglutinin stalk domain which mediates the membrane fusion and is conserved amongst different sub-types of influenza virus. This peptide is a good ca...
BACKGROUND Despite the heightened risk of serious influenza during infancy, vaccination is not recommended in infants younger than 6 months. We aimed to assess the safety, immunogenicity, and efficacy of maternal immunisation with trivalent inactivated influenza vaccine for protection of infants against a first episode of laboratory-confirmed influenza. METHODS We did this prospective, active...
background & aim: the recent study was conducted to investigate the effects of thyme extract in drinking water on immune response of broiler chickens. experimental: a total of 245 day-old broiler chicks were purchased and 20 chicks were bled for determination maternal antibody and remaining chicks divided into 5 equal groups. chickens of group a, b and c received 0.1%, 0.15% and 0.2% ofthy...
