Vaccines Treatment Options in Canada

This is a single-centered trial of a group A streptococcal (GAS) vaccine, StreptAnova™. The study is designed to assess safety and immunogenicity of three doses (0, 1, 6 months) of one dosage (600 µg protein) in healthy adults 18 through 50 years of age. Read Less

Evaluate, one month after the third dose, the lot-to-lot consistency of 3 different commercial scale production lots of the candidate vaccine in healthy HSV 1-/2- females aged 10-17 years, determined by ELISA. Absence in significant variation for both parameters among the tested lots was hypothesized. Read Less

This is a randomized, observer-blind, irrelevant comparator-controlled trial in male and female subjects ≥24 months of age and \<72 months of age. Subjects will be without symptomatic chronic cardiopulmonary disease, including recurrent wheezing. Subjects will be screened for seropositivity to RSV in a qualified serum microneutralization (MN) assay and will be excluded if titers for either RSV/A or RSV/B are \<1:16 (4 log2). Treatments will comprise an IM dose of saline placebo or RSV F vaccine on Day 0 and an IM dose of RSV F vaccine or a licensed hepatitis A vaccine on Day 28. Hepatitis A vaccine (and in one group placebo) will be used to maintain the study blind; all subjects will receive a complete course of hepatitis A vaccine as a study benefit. Read Less

Primary objective: To evaluate the clinical activity of the vaccine regimen, as indicated by progression-free survival versus the clinical activity of the reference treatment. Secondary objectives: Safety: To describe the safety profile in both treatment groups. Efficacy: To determine the objective clinical responses of patients in both treatment groups: complete response and partial response. Read Less

This is a phase 1, research study is looking at the safety and acceptability of a new vaccine adjuvant (immune booster) called PAL when combined with the seasonal flu vaccine (Fluviral) to test the safety and effectiveness of new vaccines and medications on healthy volunteers. The study will enroll approximately 48 healthy adult participants, and occur over 3 years. In the first six months/180 days of the study participants will have visits to the study site during which safety and immunogenicity outcomes will be measured. From Day 181 to Year 3, participants will be contacted by telephone or email to collect information on any adverse events. Read Less

This study will recruit 35 healthcare workers who had systemic reactions to influenza vaccine the last 2 times they were vaccinated, to ask whether influenza vaccine is indeed associated with systemic reactions in these workers. Read Less

A phase I trial conducted in a single centre, observer-blind, randomized, dose-ranging, placebo-controlled study to evaluate the safety, tolerability, and immunogenicity of 2 intramuscular injections of plant-based H7 VLP Influenza Vaccine administered to healthy adults, 18-60 years of age.

The purpose of the study is to see which of the three current provincial Meningococcal C Conjugate vaccine schedules in Canada provide the longest lasting protection against Meningococcal C disease and to see if a booster vaccination is needed. Read Less

The influenza virus, commonly called the flu, is a common source of infection in lung transplant patients and can often lead to pneumonia and possibly rejection. The annual influenza vaccine is the most important strategy used to prevent infection but it is not effective in all lung transplant patients. It has been thought that the response to the vaccine may be improved if it is given into the skin (intradermal) rather than the muscle (intramuscular). We hypothesize that a significantly greater proportion of patients will respond to vaccination using the intradermal influenza vaccine compared to the intramuscular vaccine. Read Less

The goal of the study is to assess the risk of occurrence of narcolepsy following the administration of inactivated (AS03) adjuvanted A/H1N1 pandemic influenza vaccine in the province of Quebec, Canada, using different case definitions and time intervals to disease onset, while controlling for potential confounding variables such as age, gender, season and, when possible, A/H1N1 pandemic influenza infection. Another aim is to describe the epidemiology and clinical features of narcolepsy cases with onset during the period January 1st, 2009 to December 31, 2010 in the population of Quebec. Read Less

The purpose of this study is to compare the safety and effectiveness (immune response) to one or two doses of adjuvanted H1N12009 influenza vaccine in young children. An adjuvant is an additive that can boost the immune response. The study will enroll 300 children (ages 6-35 months). Participants will receive 2 doses of adjuvanted H1N12009 vaccine 3 weeks apart. Study procedures include: medical history, blood samples and completing a memory aid. Participants will be involved in study related procedures for approximately 6 weeks. Read Less

The seasonal influenza vaccination program for 2010-2011 will be the first to follow the H1N1 pandemic of 2009. Many Canadians either had the H1N1 infection or the adjuvanted H1N1 vaccine. Both H1N1 infection and adjuvanted vaccine produced strong immune responses which could last for some time. The seasonal influenza vaccine for this fall will be a "normal" product once again, without adjuvant. It will contain 3 strains of killed, split-apart viruses that might circulate this winter, including the H1N1 pandemic strain. It is theoretically possible that giving the H1N1-containing seasonal vaccine to people who still have some immunity to H1N1 virus could result in more frequent side-effects. However, there is no good evidence that pre-existing immunity to a strain in the vaccine does increase side-effects. In short, there could be nothing out of the ordinary this fall but it would be prudent to check this before public flu vaccination programs begin. Read Less
