A Study to Evaluate Safety and Immunogenicity of 1 Booster Dose of 1790GAHB Vaccine in Healthy Adults Primed With 3 Doses of 1790GAHB Vaccine in Study H03_01TP Compared to 1 Vaccination of 1790GAHB in Either Subjects Who Received Placebo in the Same Study
GVGH Shigella Sonnei 1970GAHB is a vaccine aimed at preventing the disease caused by Shigella sonnei. A post-hoc analysis of subjects who participated in the parent study showed significantly different responses in subjects with detectable versus undetectable antibody titres at baseline, suggesting the possibility that the vaccine might not be sufficiently immunogenic in completely naïve adults. This study was then designed to further characterize the immunogenicity pr...
To evaluate the safety and immunogenicity of HIV p17/p24:Ty-VLP (virus-like particles) vaccine in uninfected volunteers. Specifically, to determine whether the vaccine formulated with and without alum induces CD8+ cytotoxic T lymphocytes ( CTLs ) that may be cross-reactive against multiple HIV-1 stains. Also, to determine whether boosting with the vaccine orally or rectally will help induce mucosal antibody responses. Induction of CD8+ CTL activity is considered a critical pro...
Shigellosis remains a serious and frequent disease throughout the world. Development of vaccines has been difficult because shigellae are habitants of and pathogens for humans only and there is no consensus about the mechanism(s) of immunity to this pathogen. Incomplete, but compelling evidence, indicates that a critical level of serium IgG anti-LPS confers immunity to shigellosis. Important data come from our clinical trial in the Israel Defense Forces (IDF) recruits. A ra...
The purpose of this project is to systematically collect clinical and nutritional outcomes information on patients treated for Shigella infection so that physicians and clinical laboratories can better define which Shigella infections are "resistant" to antibiotics and which are "susceptible", focusing on azithromycin a last-line drug to treat drug resistant Shigella
This study is an open-label, dose-escalating Phase 1 investigation of S. flexneri 2a InvaplexAR vaccine. A total of up to 40 subjects will receive one of four S. flexneri 2a InvaplexAR vaccine doses. The vaccine will be administered intranasally (without adjuvant).
This study investigates the safety and effectiveness of a preventative vaccine for parvovirus B-19 infection. Eighty-nine healthy adults ages 18-49, whose blood tests negative for B-19, will be enrolled. Participants will be randomly chosen to receive 1 of 4 possible vaccine types: low dose of the vaccine and an adjuvant (substance which assists with transfer of medication to body); high dose of the vaccine alone; high dose of the vaccine and an adjuvant; or saline (substance c...
This study will determine if PATH-wSP, a vaccine against a germ that causes pneumonia, is safe and induces immune responses in adults and toddlers. The study vaccine will be compared to placebo. First adults will receive a 2 injections of a lower dose of the vaccine or placebo, 28 days apart. If the lower dose is safe, then a higher dose will be tested. Once the safety is established in adults the lower and higher dose will be tested in toddlers, starting with the lower dose...
(1) Due to missed childhood vaccination programs, the majority of adult patients with NAFLD in Canada do not have immunity to hepatitis B. (2) Adults with NAFLD who receive the HBV vaccine have reduced immunogenic responses in the setting of obesity (i.e., protective anti-HBs titres). Aims: (1) To determine the sero-prevalence of immunity against hepatitis B in a cohort of prospectively evaluated adult NAFLD patients. (2) To prospectively determine HBV vaccine responses (anti-H...
The purpose of this study is to investigate for the broad immunological effects of administering measles vaccine (MV) and diphtheria-tetanus-whole cell pertussis vaccine (DTP) to 9 month old Gambian infants, either alone or together. Effects on vaccine-specific immune responses, innate immunity, and immune memory were studied. The hypothesis is that when MV and DTP are given together there will be more inflammation and this will interfere with generation of immunity to the vacc...

The study vaccine could be the stepping stone for the development of a multivalent broadly protective Shigel...
Yellow fever is an acute viral disease transmitted by mosquitoes in South America, Central America and Africa. It is more prevalente in males gender and the age above 15 years due to the greater exposure in the wild endemic area of yellow fever. According to the World Health Organization (WHO), a single dose of the yellow fever vaccine is sufficient to maintain protective immunity against yellow fever for a lifetime, therefore a booster dose is not required. This issue is diff...
