ZARAGOZA, Spain (AP) —
A researcher at the University of Zaragoza is spearheading efforts to combat tuberculosis, the world’s deadliest infectious disease, with a novel vaccine candidate. Clinical trial results are anticipated by 2029.
After more than two decades dedicated to tuberculosis research,a microbiologist at the University of Zaragoza is focusing on the years 2028-2029,when the results of ongoing clinical trials for the MTBVAC vaccine are expected. “The MTBVAC vaccine is extensively studied. We have significant knowledge about it, but the crucial question remains: does it work?” the researcher stated.
Reflecting on his early career, the researcher recalls his time at the Pasteur Institute beginning in 1987, working alongside Dr. Brigitte Gicquel. “I intended to stay for three months, but it turned into five years,” he recounted. His extensive work has underscored the vital role of vaccines. He cited the COVID-19 pandemic as a prime example: “Vaccines were instrumental in enabling us to return to normalcy.”
The researcher will discuss the essential function of vaccines at the sixth annual Lección Cajal, held at the Paraninfo. The lecture will explore the history of vaccinations, from their inception to pivotal moments such as the 2020 pandemic.”Vaccines were once primarily associated with children, but the COVID-19 pandemic highlighted their necessity for societal well-being,” he noted.
Despite significant progress, ample challenges remain. “Vaccines for diseases like AIDS, malaria, and tuberculosis are still needed, as the existing tuberculosis vaccine is inadequate,” he asserted. His work focuses on the MTBVAC vaccine, a unique live-attenuated strain vaccine containing all tuberculosis antigens.
Currently, a Phase 3 clinical trial is underway, evaluating the vaccine in infants across three countries: South Africa, Madagascar, and Senegal. This trial aims to vaccinate 7,000 newborns over the next two years. “We anticipate results in 2028-2029,” the researcher said.
Of particular concern are adolescents and adults, who often transmit the disease but are not vaccinated. A clinical trial has been initiated to assess the safety and efficacy of the MTBVAC vaccine in these populations. “We are in Phase 2b, not Phase 3, due to the considerable expense of vaccinating 4,200 adolescents across 15 centers in South Africa, Kenya, and Tanzania,” the researcher explained. Vaccination will occur over two years, with results expected around 2028.
The researcher emphasized that while effective tuberculosis treatments exist, a vaccine is essential for eradication. “The task is immense,” he stressed, highlighting the significant economic and logistical hurdles in ensuring universal and equitable vaccine access.”Distribution in countries that need it is lacking,” he added.
To overcome these challenges, support is crucial. “We have been working on this vaccine for over 20 years. We are close to achieving our goal, but a final push is needed,” he emphasized. While local support in Aragón is strong, national support is lacking. “The University of Zaragoza aims to make the vaccine universally accessible and affordable, so all funding has come from non-profit organizations. Spain has not invested in the clinical progress of this research,” he lamented.
“There is no national commitment to research. We feel somewhat abandoned, as it is often deprioritized because Spain lacks experience in developing a vaccine from Phase 1 to Phase 3,” the researcher stated. He noted that Spain excels in Phase 3 clinical trials but primarily with “medicines that are not our own.”
The researcher stressed the lengthy and costly nature of the work and appealed for broad support, from political parties to the monarchy. “This has taken 25 years and will take more,” he concluded. “We need people to feel like it’s their own.”
Tuberculosis Vaccine Research: A Q&A with the University of zaragoza Researcher
This article provides insights into the ongoing research for a tuberculosis vaccine, based on information from a microbiologist at the University of Zaragoza. The focus is on the MTBVAC vaccine and the clinical trials underway.
Key Questions Answered:
- What is the MTBVAC vaccine and what is its purpose?
- what stage are the clinical trials for the MTBVAC vaccine currently in?
- What are the challenges in developing and distributing a tuberculosis vaccine?
- How long has this research been going on?
- What is the researchers’ call to action?
What is the MTBVAC vaccine, and why is it crucial?
The MTBVAC vaccine is a novel live-attenuated strain vaccine containing all tuberculosis antigens. The primary goal is to create a more effective tuberculosis (TB) vaccine than the current one, aiming to eradicate the world’s deadliest infectious disease.
What stage are the clinical trials for the MTBVAC vaccine currently in?
Currently,there are two main clinical trials underway:
-
Phase 3 Trial (Infants): This trial is evaluating the vaccine in infants across South Africa,Madagascar,and Senegal. The aim is to vaccinate 7,000 newborns over two years, with results expected in 2028-2029.
-
Phase 2b Trial (Adolescents and Adults): A trial is also assessing the vaccine’s safety and efficacy in adolescents and adults. This trial involves vaccinating 4,200 individuals across 15 centers in South africa, Kenya, and Tanzania, with results anticipated around 2028.
How crucial is a new vaccine for the eradication of Tuberculosis?
While effective treatments for TB exist, a new vaccine is considered essential for complete eradication. The existing TB vaccine is inadequate, making the advancement of a more effective vaccine a high priority.
Can you give a brief history of vaccine development as mentioned by the researcher?
The researcher discusses the history of vaccines from their inception to pivotal moments such as the 2020 pandemic, highlighting the COVID-19 pandemic as a exhibition of the vital role vaccines play in enabling a return to normalcy. Vaccines were once primarily associated with children, but the COVID-19 pandemic highlighted their necessity for societal well-being.
What are the main challenges in developing and distributing a tuberculosis vaccine?
The challenges include:
- Financial Hurdles: The cost of clinical trials, particularly for Phase 2b trials, is notable.
- Logistical Hurdles: Ensuring universal and equitable vaccine access, especially in countries that need it most, presents considerable logistical challenges.
How long has this research been ongoing, and what is the current funding situation?
The researcher has been dedicated to TB research for over two decades. The MTBVAC vaccine development has been a 20-year endeavor. All funding for the clinical progress of this research has come from non-profit organizations. The researcher laments the lack of national investment from Spain, which does not have much experience in developing a vaccine from Phase 1 to Phase 3.
What is the researcher’s primary appeal?
The researcher emphasizes the need for broad support, including both financial and moral backing, to overcome the final hurdles in vaccine development and ensure its accessibility. As the researcher stated, “We need people to feel like it’s their own.” His goal is “to universally accessible and affordable.”
