A clinical trial for an experimental Ebola vaccine is underway at the Halifax-based Canadian Center for Vaccinology (CCfV).
Dr. Scott Halperin, director of the CCfV and professor of Microbiology & Immunology at H漫画 Medical School, is the medical lead for the trial, which is being led by the Canadian Immunization Research Network (CIRN). CCfV will be the only vaccine test site in the country.
鈥淲e鈥檝e conducted many Phase 1 clinical trials, but this one is particularly exciting given the urgency to develop an effective vaccine,鈥� says Dr. Halperin, who鈥檚 also head of Pediatric Infectious Diseases at the IWK Health Centre.
The vaccine is made with a live animal virus called vesicular stomatitis virus (VSV). It doesn鈥檛 contain the Ebola virus.
鈥淔or the Ebola vaccine, the VSV has been genetically modified to produce a protein. This protein causes the immune system to generate antibodies that fight Ebola infection,鈥� explains Dr. Halperin. 鈥淭he vaccine can鈥檛 cause Ebola.鈥�
40 volunteers needed
Forty people aged 18-65 are needed for the clinical trial. Because of the extensive eligibility requirements for participants, approximately 120 people will go through initial screening.
The Canadian-made vaccine is one of two experimental Ebola vaccines undergoing tests in humans. The Halifax trial is taking place concurrently with trials in the United States in an effort to expedite the collection of information needed to do further studies in larger populations.
鈥淲e鈥檒l be looking to see whether lower doses of the vaccine can induce an immune response against Ebola,鈥� explains Dr. Halperin. 鈥淎nd we鈥檒l also be looking at the effect of the vaccine on a broader age range than was included in the other trials.鈥�
The preliminary CCfV trial results are expected in early 2015.
Canadian effort to fight global threat
Dr. Gregory Taylor, Canada鈥檚 chief public health officer, says this experimental Ebola vaccine is the result of years of innovation and hard work by Canadian scientists.
鈥淭he results of these clinical trials will offer us valuable data about the safety and effectiveness of our vaccine and will hopefully provide us with the information we need to proceed with further clinical trials in the countries most affected by Ebola,鈥� says Dr. Taylor.
CIRN, the lead group for the clinical trial, is comprised of more than 100 cross-disciplinary experts in vaccine-related research from more than 40 Canadian institutions. The Canadian Institutes of Health Research (CIHR) and the Public Health Agency of Canada (PHAC) jointly fund CIRN鈥檚 vaccine research.
"Canadian health researchers are recognized worldwide for their considerable expertise and leadership in carrying out high quality clinical trials,鈥� says Alain Beaudet, president of CIHR. 鈥淭his trial demonstrates the commitment and collaborative spirit of the Canadian health research community and its capacity to rapidly mobilize in response to a global crisis."
Infectious diseases is one of H漫画 Medical School鈥檚 core research strengths. More than 40 H漫画 investigators, all affiliated with the IWK or Capital Health, are pursuing vaccine research at the Canadian Center for Vaccinology.
