With advent and development of DNA recombinant technology and advantages of p. pastoris expression system, fusion (F) protein of PPRV expression, because of effective immunodominant role could be an appropriate candidate for production of recombinant vaccine against PPR disease. In this study, F gene of PPRV Nigeria 75/1 strain (1637 bp) was amplified using RT-PCR and purified. It was then cl...
Aim and Background: By Attention to gene sequence and each amino acid codon in host which express protein, also in order to probable vaccine production against influenza A, a major cause of mortality in a year,this research was carried out. M2 protein is conserved and it can be a proper candidate vaccine for influenza infection. Materials and Methods: Present research was an experimental study....
Leishmaniasis is caused by protozoan Leishmania parasites that are transmitted through female sandfly bites. The disease is predominantly endemic to the tropics and semi-tropics and has been reported in more than 98 countries. Due to the side effects of anti-Leishmania drugs and the emergence of drug-resistant isolates, there is currently no encouraging prospect of introducing an effective ther...
BACKGROUND The nasal vaccine candidate (NASVAC), comprising hepatitis B virus (HBV) surface (HBsAg) and core antigens (HBcAg), has been shown to be highly immunogenic in animal models. METHODS A phase I double-blinded, placebo-controlled randomized clinical trial was carried out in 19 healthy male adults with no serologic markers of immunity/infection to HBV. This study was aimed at exploring...
Background: With one-third of the world’s population infected, tuberculosis (TB) is one of the most common infectious diseases and a major public health problem, especially in developing countries. The efficacy of the BCG vaccine for controlling the disease in adults is poor. The development of an effective TB vaccine is a global objective. An effective tuberculosis vaccine should s...
The first candidate rotavirus vaccine was a live attenuated oral vaccine made by the classical empirical method of serial passage of virus in tissue culture cells. Current tetravalent vaccine candidates that are in the final stages of efficacy testing in the United States were made by genetic reassortment. This article briefly highlights how advances in the basic understanding of the molecular ...
BACKGROUND Genital infection with herpes simplex virus 2 (HSV-2) is linked to an increased risk of infection with human immunodeficiency virus (HIV) in areas such as Sub-Saharan Africa. Thus, an effective genital herpes vaccine would be an important weapon in the fight against HIV/AIDS. METHODS To test whether a current vaccine candidate can protect against HSV-2 from Sub-Saharan Africa, we e...
BACKGROUND A live oral Vibrio cholerae O1 El Tor vaccine candidate, Peru-15, was studied for safety, immunogenicity, and excretion in phase 1 (inpatient) and phase 2 (outpatient) studies of Bangladeshi adults.METHODs. The study was conducted among adults, by use of a double-blind, randomized, placebo-controlled design. A single dose of Peru-15 (approximately 2 x 108 cfu) or placebo (buffer only...
Background and Aims: Glycoprotein B (gB) is among the most important immunogenic proteins of HSV-1 that is now being used as recombinant vaccine to induce protectively against the virus. It is believed that gB is responsible for induction of neutralizing antibody and up to 90% of CTL (Cytotoxic T Cell) activity against HSV-1 in some haplotypes. Methods: In the present study the antibody titer ...
UNLABELLED Adenovirus vectors are widely used as vaccine candidates for a variety of pathogens, including HIV-1. To date, human and chimpanzee adenoviruses have been explored in detail as vaccine vectors. The phylogeny of human and chimpanzee adenoviruses is overlapping, and preexisting humoral and cellular immunity to both are exhibited in human populations worldwide. More distantly related ad...
