Background: The pandemic and regional influenza outbreaks resulting from antigenic variation of influenza viruses have been the subject of numerous studies which are crucial to the preparation of the vaccine. Frequent global winter outbreaks of influenza viruses require a constant surveillance of emerging influenza variants in order to develop efficient influenza vaccine. Methods: This study wa...
Background and Aims: Influenza is one of the main respiratory infections of humans, responsible for 300,000–500,000 annual deaths world-wide. Vaccination is one of the best ways to prevent infections including influenza. Influenza virosomes are virus-like particles, which retain the cell binding and membrane fusion properties of the native virus, but lack the ribonucleoprotein (RNP). A vi...

Methods: Data of this study were obtained from the surveillance system of the Center for Communicable Disease Control, the review of records, documents, books and pub...
background and aims: influenza a viruses are important pathogens for humans especially in pandemic episodes. two adamantane derivates, amantadine and rimantadine, are used for prophylaxis and treatment of influenza a virus infections. however, single amino acid substitutions in the m2 transmembrane domain which lead to amantadine resistance of these viruses occur at residues 26, 27, 30, 31 or 3...
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...
