background influenza is a world-wide public health concern. it is one of the most important viral causes of acute respiratory illness, affecting all age groups, recurring several times during a lifetime. we assessed the antibody titers after vaccination against influenza among hiv-infected patients and health care workers (hcws). patients and methods during this before-after study, the antibody...
BACKGROUND The virus-specific cytotoxic T lymphocyte (CTL) induction is an important target for the development of a broadly protective human influenza vaccine, since most CTL epitopes are found on internal viral proteins and relatively conserved. In this study, the possibility of developing a strain/subtype-independent human influenza vaccine was explored by taking a bioinformatics approach to...
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 stu...
background and aims: the novel approaches in influenza vaccination have targeted more conserved viral proteins such as nucleoprotein (np) to provide cross protection against all serotypes of influenza a viruses. influenza specific cytotoxic t lymphocytes (ctl) are able to lyse influenza-infected cells by recognition of np, the major target molecule in virus for ctl responses. on the other hand,...
background and aims: influenza (flu) is a respiratory infection in mammals and birds. it is caused by an rna virus in the family orthomyxoviridae. the virus is divided into three main types. influenza virus type a is found in a wide variety of bird and mammal species and can undergo major shifts in immunological properties. hemagglutinin (ha) is an important influenza virus surface antigen that...
Whether the 2009 pandemic H1N1 influenza vaccine can induce heterosubtypic cross-protective anti-hemagglutinin (HA) neutralizing antibodies is an important issue. We obtained a panel of fully human monoclonal antibodies from the memory B cells of a 2009 pandemic H1N1 influenza vaccine recipient. Most of the monoclonal antibodies targeted the HA protein but not the HA1 fragment. Among the analyz...
Aim and Background: By Attention to gene sequence and each amino acid codon in host which express protein, also in order to probable vaccine production against influenza A, a major cause of mortality in a year,this research was carried out. M2 protein is conserved and it can be a proper candidate vaccine for influenza infection. Materials and Methods: Present research was an experimental study....
BACKGROUND A mass vaccination has been implemented to prevent the spread of 2009 pandemic influenza virus in China. Highly limited information is available on whether this vaccine induces cross-reactive neutralization antibodies against other subtypes of influenza viruses. METHODS We employed pseudovirus-based assays to analyze heterosubtypic neutralization responses in serum samples of 23 re...
An increasing number of infections of highly pathogenic avian influenza virus (H5N1) in humans has been reported in South-East Asia and other areas of the world. High mortality (>60%) of this viral infection and its pathosis of systemic infection are features of this new human disease. Moreover, there is great concern that this avian H5N1 virus could cause a pandemic of new influenza in humans,...
