<p class="abstract"><strong>Background:</strong> Chlamydia infections in humans and animals pose a significant burden on health systems worldwide. While widespread screening, adequate treatment, and prevention programs are helpful to increase awareness and improve screening rates, infection rates are rising. A vaccine is necessary to slow increasing rates, manage negative consequences, and prevent possible antibiotic resistance. We present the current landscape regarding the innovations for commercial vaccine development in a “one-health” context.</p><p class="abstract"><strong>Methods:</strong> We developed a unique dataset containing data of patent documents intended for human and veterinary use, and clinical trials in order to provide a detailed description of the global chlamydia vaccine developments.</p><p class="abstract"><strong>Results:</strong> Analysis of patents and clinical trials intended for human use presented a vaccine field that is underdeveloped, with no commercial human chlamydia vaccine available, and two potential candidates in a phase 1 clinical trial. Comparing innovations concerning chlamydia vaccine developments for both human and veterinary patents, it was clear that these fields are very different and independent of each other. The field is small, and certain companies and researchers show repeated interest. Partnerships among applicants and those involved in chlamydia vaccine innovation would be an important step to take towards innovating and developing an effective vaccine.</p><p class="abstract"><strong>Conclusions: </strong>We have shown that North America is considered, by patent application, to hold the most potential for a chlamydia vaccine, specifically against the <em>Chlamydia trachomatis </em>strain. A new vaccine is likely to be a subunit vaccine with components of the major outer membrane protein antigen.</p>
This study explored to what degree economic development and improvement of healthcare are associated with lower respiratory tract infection (LRTI) mortality. A correlation analysis between LRTI mortality and Gross Domestic Product (GDP) per capita, and the Health Access and Quality Index (HAQI), respectively was conducted for 15 countries in East and South-East Asia. The results revealed a dramatic decrease in LRTI mortality in total populations for lower-middle income (LMI) countries but at the same time an increase in upper-middle income (UMI) and high-income (HI) countries. A highly significant ( P < .001) growth-dependent relationship between LRTI mortality and economic growth was observed. Improvements in HAQI were significantly associated with a decrease in LRTI mortality in LMI countries, but an increase in UMI and HI countries. The decline of LRTI mortality amongst children in LMI countries is an encouraging trend and efforts against LRTI must be continued, though not at the expense of preparing health systems for the growing burden.
<p class="abstract"><strong>Background:</strong> Respiratory tract infections (RTIs) pose a significant burden on health systems worldwide. Progress has been booked in reducing RTI disease burden through development of diagnostics, therapeutics and vaccines, though most efforts often fail to address the contribution of non-influenza viruses. Increasing awareness and the prevailing unmet need has resulted in the establishment of initiatives that aim to explore ways in which to extend innovation efforts for influenza to the broad range of respiratory viruses. This study will provide a detailed description of the state of the RTI market in Asia.</p><p class="abstract"><strong>Methods:</strong> By developing a dataset containing data from patent documents and clinical trials (CTs) we aimed to provide a detailed description of the RTI market in Asia.</p><p class="abstract"><strong>Results:</strong> We found a downward patent filing trend in respiratory diagnostics but a high number of phase 3 studies. A strong preference for the development of therapeutics and vaccines targeting bacterial pneumonia and influenza became apparent, whereas less attention is given towards product development targeting non-influenza viruses.</p><p class="abstract"><strong>Conclusions: </strong>The findings indicate a mature respiratory diagnostics market with minor industrial interest but at the same time an evolving RTI CT market with a strong late-stage pipeline. Asia represents only a handful of studies related to non-influenza viruses, mostly conducted by non-profit organisations. The business segment appears to focus upon product development for more profitable respiratory infections thereby suggesting that involvement and engagement of the industry within global initiatives and efforts to increase innovation for non-influenza viruses is not optimal.</p>
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
