Influenza viruses continue to be a major health threat in human and bird populations. The improvements in formulation and production level of the current influenza vaccines are not sufficient to afford complete protection. The continuous antigenic drifts and emergence of endemic and zoonotic strains make influenza vaccine planning difficult. Concern about the emergence of new influenza pandemic...

Background: Problems of live and inactivated influenza vaccines such as, increasing emerge and re-emerge viruses with high human mortality, current epidemics of influenza and direct transmission of avian viruses to human, affect the vaccination program. DNA vaccines as third generation of vaccines is specially considered for control of influenza in human and poultry. The main advantage of these...

Background: Influenza virus is a major infectious pathogen of the respiratory system causing a high degree of morbidity and mortality annually. The worldwide vaccines are decided and produced annually by World Health Organization and licensed companies based on the samples collected from all over the world. The aim of this study was to determine phylogenecity and heterogenecity of the circulati...

Background and purpose: Influenza virus is one of the most important respiratory infectious agents. Viral antigenic variations are major problems for vaccine production process. At present, many researches have focused on conserved domains of influenza virus antigenic peptides for subunit vaccine development. Hemagglutinin small subunit (HA2) and the 23 amino acid extracellular N-terminal domai...

Background and Aims: Influenza A virus of Orthomyxoviridae family is able to create pandemic influenza. Vaccination is the most effective way to prevent influenza virus infection. Matrix protein 2 (M2) is a homotetramer ion channel with 97 amino acids length and highly conserved among influenza viruses and is considered for development of a universal influenza vaccine. Materials and Methods: We...

Background and Aims: Influenza vaccine production process is time-consuming with little-to-no cross-protection which requires annual adjustment. The construction of a universal vaccine to deal with the pandemics and epidemics which occasionally threat human population is the aim of many researches worldwide. Today, influenza vaccines are mostly against two major antigenic proteins, hemagglutini...

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...
