Antimicrobial resistance (AMR) is a high priority across countries as it increases morbidity, mortality and costs. Concerns with AMR have resulted in multiple initiatives internationally, nationally and regionally to enhance appropriate antibiotic utilization across sectors to reduce AMR, with the overuse of antibiotics exacerbated by the COVID-19 pandemic. Effectively tackling AMR is crucial for all countries. Principally a narrative review of ongoing activities across sectors was undertaken to improve antimicrobial use and address issues with vaccines including COVID-19. Point prevalence surveys have been successful in hospitals to identify areas for quality improvement programs, principally centering on antimicrobial stewardship programs. These include reducing prolonged antibiotic use to prevent surgical site infections. Multiple activities centering on education have been successful in reducing inappropriate prescribing and dispensing of antimicrobials in ambulatory care for essentially viral infections such as acute respiratory infections. It is imperative to develop new quality indicators for ambulatory care given current concerns, and instigate programs with clear public health messaging to reduce misinformation, essential for pandemics. Regular access to effective treatments is needed to reduce resistance to treatments for HIV, malaria and tuberculosis. Key stakeholder groups can instigate multiple initiatives to reduce AMR. These need to be followed up.

Aim:Global expenditure on medicines is rising up to 6% per year driven by increasing prevalence of non-communicable diseases (NCDs) and new premium priced medicines for cancer, orphan diseases and other complex areas. This is difficult to sustain without reforms.Methods:Extensive narrative review of published papers and contextualizing the findings to provide future guidance.Results:New models are being introduced to improve the managed entry of new medicines including managed entry agreements, fair pricing approaches and monitoring prescribing against agreed guidance. Multiple measures have also successfully been introduced to improve the prescribing of established medicines. This includes encouraging greater prescribing of generics and biosimilars versus originators and patented medicines in a class to conserve resources without compromising care. In addition, reducing inappropriate antibiotic utilization. Typically, multiple measures are the most effective.Conclusion:Multiple measures will be needed to attain and retain universal healthcare.

Introduction: Dengue virus (DENV) is a serious global health problem. CYD-TDC (Dengvaxia ® ) was the first vaccine to gain regulatory approval to try and address this problem. Aim: Summarize all available evidence on the immunogenicity, efficacy and safety of the CYD-TDV dengue vaccine. Method: Meta-analysis and systematic review. Results: The best and worst immunogenicity results were for DENV4 and DENV1, respectively. Vaccine efficacy of 60% was derived from studies with participants aged 2–16 years old, with DENV4 and DENV2 presenting the best and worst results, respectively. Erythema and swelling were more frequent with CYD-TDV. No differences were detected for systemic adverse events. Conclusion: CYD-TDV showed moderate efficacy in children and adolescents. From the immunogenicity results in adults, we can expect satisfactory efficacy from vaccination in this population.

Antimicrobial resistance (AMR) poses a significant threat, particularly in low- and middle-income countries (LMICs), exacerbated by inappropriate antibiotic use, access to quality antibiotics and weak antimicrobial stewardship (AMS). There is a need to review current evidence on antibiotic use, access, and AMR, in primary care across key countries.Areas covered: This narrative review analyses publications from 2018 to 2024 regarding access, availability and use of appropriate antibiotics. There were very few studies focussing on a lack of access to antibiotics in primary care. However, there was considerable evidence of high rates of inappropriate antibiotic use, including Watch antibiotics, typically for minor infections, across studied countries exacerbated by patient demand. The high costs of antibiotics in a number of LMICs impacts on their use resulting in short courses and sharing of antibiotics. This can contribute to AMR alongside the use of substandard and falsified antibiotics. Overall, limited implementation of national action plans, insufficient resources, and knowledge gaps, affects sustainable development goals to provide routine access to safe, effective and appropriate antibiotics. There is a clear need to focus health policy on the optimal use of essential AWaRe antibiotics in primary care settings to reduce AMR in LMICs.
