Influenza vaccines: present and future.

Control of Highly Pathogenic Avian Influenza by Evidence-Based Vaccinology: Past Progress, Future Prospect

Background and Objectives: Highly pathogenic avian influenza (HPAI) viruses are particularly important due to huge economic consequences and public health concerns. During recent years, because of the severity of epidemics and failure in the control and eradication of HPAI, vaccination has been introduced into the National Prevention and Control Program of some countries, including Iran. This a...

The effect of the hexanic extracts of fig (Ficus carica) and olive (Olea europaea) fruit and nanoparticles of selenium on the immunogenicity of the inactivated avian influenza virus subtype H9N2

Influenza is a contagious viral disease that is seen in avian, human and other mammals, so its control is important. Vaccination against influenza virus subtype H9N2 is one of the ways in controlling program, for this reason several vaccines has been produced. Recently, application of inactivated oil-emulsion vaccines in poultry for controlling low pathogenic avian influenza is increasing. At p...

Vaccination of Chicks with Experimental Newcastle Disease and Avian Influenza Oilemulsion Vaccines by ln Ovo Inoculation

Evaluation and Comparison of the Potential Immunogenicity of Two Commercial Inactivated Bivalent Newcastle and Avian Influenza Vaccines in SPF Chicken

In the present study, the potency and immunogenicity of the inactivated bivalent vaccine of Newcastle disease (ND) and avian influenza (AI) produced by Razi institute in Iran were compared with a similar imported vaccine administered by standard methods to specific-pathogen-free (SPF) chicken. A total of 150 twenty-one-day-old SPF chickens were used for evaluating Razi and imported inactivated ...

تغییرات ژنتیکی ویروس و فرار از سامانه ایمنی، چالش‌های پیش‌رو علیه آنفلوآنزا: مقاله مروری

The spread of influenza viruses in multiple bird and mammalian species is a worldwide serious threat to human and animal populations' health and raise major concern for ongoing pandemic in humans. Direct transmission of the avian viruses which have sialic acid specific receptors similar to human influenza viruses are a warning to the emergence of a new mutant strain that is likely to share mole...

Virus shedding after H9N2 strain challenge of SPF Chickens immunized by an experimental Nano-Adjuvant and commercial oil emulsion avian influenza (H9N2) vaccines

Abstract Background and Aims: Vaccination of poultry has a major impact on the prevention and control of avian influenza viruses. Nanobiotechnology techniques provide a new approach for improvement of influenza vaccine efficacy. In this study, efficacy of an inactivated nano-adjuvant vaccine developed based on an endemic H9N2 virus was evaluated in SPF chickens. Materials and Methods: I...
