background and aims: influenza vaccination is one of the best way to prevent and control influenza worldwide. it is manufactured by who-licensed companies based on the who expertise committee annually. the aim of this study was partial quality control of the commercial human influenza vaccine 2008-9 and its matching with the circulating strains. materials and methods: the trivalent imported vac...

Background: Due to high genetic variation in human leukocyte antigen )HLA( alleles, epitope-based vaccines don’t show equal efficacy in different human populations. therefore, we proposed a multi-epitope vaccine against SARS-CoV-2 for Iranian populations. Materials and Methods: For this purpose, the proteins without allergenicity and high antigenicity as well as conservancy level from SARS-CoV...

Noroviruses (NoVs), an important pathogenic agent of foodborne illness, lead to acute and chronic gastroenteritis in humans of all ages and to travelers’ diarrhea. Many genotypes exist in nature; GII.4 is widely known as the most predominant. Outbreaks mostly occur in semi-closed settings. Although the disease is self-limited to person, many cases have resulted in death, which has raised more c...

Leptospirosis caused by infection with pathogenic leptospires, which is the most prevalent zoonotic disease in the world. The outer membrane proteins (OMPs) of pathogenic leptospires such as LipL41 play a crucial role in pathogenesis of this disease. Therefore a major challenge to develop an effective vaccine against leptospirosis is application of basic research on the OMPs of leptospires to i...

objective: today, aids is considered as a global problem and many efforts to generate an effective vaccine against this disease have been made, but remain inconclusive. dna vaccines are a member of the new generation of vaccines that can efficiently stimulate the immune system. however, recent findings indicate low immunogenicity for these vaccines and it is believed that these types of vaccine...

Vaccine development faces major difficulties partly because of genetic variation in both infectious organisms and humans. This causes antigenic variation in infectious agents and a high interindividual variability in the human response to the vaccine. The exponential growth of genome sequence information has induced a shift from conventional culture-based to genome-based vaccinology, and allows...

newcastle is a significant avian disease continuing to cause considerable loss. developments in genetic engineering have led to plant-based platforms for human and animal vaccine production. recombinant vaccine production in hairy root systems have several advantages over stable expression in whole plants, including high growth rates, ready genetic manipulations, high levels of recombinant prot...

BACKGROUND Re-emergence of pertussis has been reported in Iran despite a high rate of vaccination coverage. Low efficacy of the vaccine might be due to the genetic divergence between clinical versus vaccine strains. In the current study, the genetic profiles of clinical isolates and vaccine strains of Bordetella pertussis (B. pertussis) were assessed by using Pulsed Field Gel Electrophoresis (P...

Congenital rubella syndrome still occurs throughout the world despite an effective vaccine being used in developed countries. Heat and light lability, as well as contraindications in immunocompromised persons, limit the use of the vaccine. An improved, more durable and less reactive rubella vaccine such as a peptide or subunit vaccine would address these unmet needs. We have sought to identify ...
