background: adjuvants are used to increase the immunogenicity of new generation vaccines, especially those based on recombinant proteins. despite immunostimulatory properties, the use of bacterial lipopolysaccharide (lps) as an adjuvant has been hampered due to its toxicity and pyrogenicity. brucella abortus lps is less toxic and has no pyrogenic properties compared to lps from other gram negat...
BACKGROUND Vaccines against human papillomavirus (HPV) infection have the potential to reduce the burden of cervical cancer. School-based delivery of HPV vaccines is cost-effective and successful uptake depends on school teachers' knowledge and acceptability of the vaccine. The aim of this study is to assess primary school teachers' knowledge and acceptability of HPV vaccine and to explore faci...
vaccination against mumps is included in world health organization (who) program of global immunization. safety and efficacy of vaccines must be confirmed by control units in charge of public health. in iran, the secondary control on potency of vaccine has not been set up yet. we decided to overcome this problem by developing who and nibsc methods in food and drug control lab. nine dilutions o...
Although there have been several reports on the efficacy assessment of a Salmonella enterica serovar Enteritidis vaccine against intestinal and parenchymatous organ diseases of laying hens, no public health risk characterization of its long-term effect on eggs has been reported. In this study, we attempted to assess the public health effect of an inactivated S. enterica serovar Enteritidis vacc...
PURPOSE Dengue virus infection is now a global problem. Currently, there is no licensed vaccine or proven antiviral treatment against this virus. All four serotypes (1-4) of dengue virus can infect human. An effective dengue vaccine should be tetravalent to induce protective immune responses against all four serotypes. Most of dengue vaccine candidates are monovalent, or in the form of physical...
In this article we discuss the following: (1) acellular vaccines are immunogenic, but responses vary by vaccine; (2) pertussis antibody levels rapidly wane but promptly increase after vaccination; (3) whole-cell vaccines vary in immunogenicity and efficacy; (4) whole-cell vaccines and naturally occurring pertussis generate predominantly T-helper 1 (Th1) responses, whereas acellular vaccines gen...
An understanding of the nature of the immune response to asexual erythrocytic stages of malaria parasites will facilitate vaccine development by identifying which responses the vaccine should preferentially induce. The present study examined and compared the immune responses of NIH mice in either single or mixed infections with avirulent (DK) or virulent (DS) strains of Plasmodium chabaudi adam...
background: cervical cancer has been shown to be highly associated with human papillomavirus (hpv) infection. the viral oncogenes e6 and e7 are constantly expressed by the tumor cells and are therefore potent targets for therapeutic genetic vaccination. in the present study, it was investigated the potential effect of hpv-16 e6, e7 and l1 co-administration to activate specific cytotoxic t lymph...
BACKGROUND This study is among the first to explore geographic factors that may be associated with human papillomavirus (HPV) vaccine uptake in the United States. METHODS Data from the 2011 and 2012 National Immunization Survey-Teen for 20,565 female adolescents aged 13 to 17 years were analyzed to examine associations of HPV vaccine initiation (receipt of at least one dose) with ZIP code-lev...
