Objectives: Influenza disease considered to be more sever and complicated in old age persons, because immune response diminish in this group. This disease is one of the main causes of mortality in elder people. The prevalence of influenza disease in elderly are living in nursing home is more in compare if they dwell in community. We studied the effect of influenza vaccine on the incidence and n...
With the exception of the live attenuated influenza vaccine there have been no substantial changes in influenza vaccine strategies since the 1940's. Here we report an alternative vaccine approach that uses Adenovirus-vectored centralized hemagglutinin (HA) genes as vaccine antigens. Consensus H1-Con, H3-Con and H5-Con HA genes were computationally derived. Mice were immunized with Ad vaccines e...
A new avian-origin influenza virus emerged near Shanghai in February 2013, and by the beginning of May it had caused over 130 human infections and 36 deaths. Human-to-human transmission of avian-origin H7N9 influenza A has been limited to a few family clusters, but the high mortality rate (27%) associated with human infection has raised concern about the potential for this virus to become a sig...
Avian influenza virus (H5N1) has caused serious infections in human beings. This virus has the potential to emerge as a pandemic threat in humans. Effective vaccines against H5N1 virus are needed. A recombinant Bombyx mori baculovirus, Bmg64HA, was constructed for the expression of HA protein of H5N1 influenza virus displaying on the viral envelope surface. The HA protein accounted for approxim...
an experimental inactivated oil-emulsion h9n2 avian influenza vaccine was formulated with 3 parts ofinactivated avian influenza antigen a/chicken/iran/101/1998(h9n2) emulsified in 7 parts of oil adjuvant.twelve week-old specific pathogen-free (spf) chickens were divided into seven groups of 10 birds. sixgroups were vaccinated with 1, 1/10th, 1/50th, 1/100th, 1/200th and 1/400th field dose of th...
Human influenza A(H3N2) viruses that predominated during the moderately severe 2014-2015 influenza season differed antigenically from the vaccine component, resulting in reduced vaccine effectiveness (VE). To examine antibody responses to 2014-2015 inactivated influenza vaccine (IIV) and live-attenuated influenza vaccine (LAIV) among children and adolescents, we collected sera before and after ...
This report for the 2013-2014 influenza season summarizes the results of influenza surveillance carried out by the DoD Global, Laboratory-based, Influenza Surveillance Program, which is managed by the U.S. Air Force School of Aerospace Medicine Epidemiology Consult Service and Epidemiology Laboratory at Wright-Patterson Air Force Base, OH. Sentinel sites submitted 3,903 specimens for clinical d...
Human influenza is a seasonal disease associated with significant morbidity and mortality. The most effective means for controlling infection and thereby reducing morbidity and mortality is vaccination with a three inactivated influenza virus strains mixture, or by intranasal administration of a group of three different live attenuated influenza vaccine strains. Comparing to the inactivated vac...
The currently available vaccines against influenza are viral strain specific and, hence, their efficacy is limited when the circulating strain is not the one included in them. We review herewith some of the more recently developed influenza vaccines and further describe our own data on the design of epitope-based broad-spectrum vaccine for human use. This vaccine is comprised of recombinant fla...
BACKGROUND Individuals infected with human immunodeficiency virus (HIV) are at increased risk for severe influenza, yet immune responses to standard-dose intramuscular (IM) influenza vaccine are suboptimal in this population. Intradermal (ID) delivery of influenza vaccine might improve immune response through enhanced stimulation of dendritic cells. METHODS We conducted a randomized, double-b...
