BACKGROUND The current live vaccinia virus vaccine used in the prevention of smallpox is contraindicated for millions of immune-compromised individuals. Although vaccination with the current smallpox vaccine produces protective immunity, it might result in mild to serious health complications for some vaccinees. Thus, there is a critical need for the production of a safe virus-free vaccine agai...
background: antibody production in patients with end-stage kidney disease impairs due to several mechanisms. there are different ways to improve response rate to hepatitis b (hb) vaccine. in this study we evaluated the effect of tetanus-diphtheria toxoid (td) vaccine on hbs antibody (ab) level while being given simultaneously with hb vaccine. methods: we recruited 43 hemodialysis and 20 perito...
background: cell mediated immunity, especially cytotoxic t cell responses against hiv-1 infection, plays a critical role in controlling viral replication and disease progres-sion. dna vaccine is a novel technology which is known to stimulate strong cellular immune responses. many dna vaccines have been tested for hiv infection but there is still no effective vaccine against this infection. cons...
The Bacille Calmette Guérin (BCG) vaccine is the only routine vaccination at birth that effectively induces neonatal T-helper 1 (Th1)-polarized immune responses. The primary cytokine that drives CD4+ T-cell Th1 differentiation is interleukin (IL)-12 p70, a heterodimeric cytokine composed of the IL-12 p35 and IL-12 p40 subunits. We therefore examined the mechanisms involved in BCG vaccine stimul...
