Payam Nahid welcomes everyone to the Bay Area Launch Event for the Lancet Global Health 2050 Report.

On January 22, the University of California, San Francisco (UCSF), University of California, Berkeley (UC Berkeley), Stanford University (Stanford), and the Bay Area Global Health Alliance co-hosted the Bay Area launch of the Lancet Commission on Investing in Health report, Global Health 2050: The Path to Halving Premature Death by Mid-Century, bringing together Bay Area students, researchers, and other key stakeholders to explore the significant findings of the report, discuss next steps, and highlight the priorities for follow-up studies. 

The report, published in October 2024, outlines how countries can reduce their rates of premature death by 50% by the year 2050. ​​It identifies 15 priority conditions, ranging from infectious diseases and maternal health to non-communicable diseases (NCDs), that account for significant life expectancy disparities. 

“We share universal principles, and we are united in the work of saving lives, improving health, and advancing equity. These principles are not confined by nations, borders, or political movements, and they endure, especially in challenging times.” – Payam Nahid, Executive Director of UCSF IGHS and Alliance Board Member

The launch event was held at a timely moment, as the global health community navigates shifts brought by the new political administration’s directives. Payam Nahid, executive director of UCSF Institute for Global Health Sciences (IGHS) and Alliance board member, delivered a message of optimism amidst the uncertainty, emphasizing the critical importance of collaboration in addressing global health challenges. 

“We share universal principles and we are united in the work of saving lives, improving health, and advancing equity. These principles are not confined by nations, borders, or political movements, and they endure, especially in challenging times,” Nahid said. “This report is not just a vision for the future; it is a call to action for justice and health equity,” he continued, highlighting the report as a framework for inspiring institutions and nations to drive impactful progress in global health over the next 25 years.

Emphasizing the transformative potential of focused health investments, Gavin Yamey, director of the Center for Policy Impact in Global Health at Duke Global Health Institute, introduced the report’s seven key messages:

  • The “50 by 50” goal: Countries can achieve a 50% reduction in the probability of premature death (before age 70) by 2050. This target is based on historical evidence, as 37 countries, including seven of the world’s most populous nations, have achieved similar progress in the past. Continued scientific advancements make this goal feasible.
  • Focus on 15 Priority Conditions: These conditions account for the majority of life expectancy disparities between the high-performing nations and other regions and include eight infectious and maternal conditions, such as HIV, tuberculosis, and maternal mortality, and  seven NCDs and injuries, such as diabetes, cancer, and road traffic injuries.
  • Resetting Universal Health Coverage (UHC): The report argues for a “reset” to UHC, proposing a modular approach, focusing on delivering 19 core modules that target the 15 priority conditions. These modules include interventions like childhood vaccinations, maternal care, and palliative care.
  • The “Arrow Mechanism” for Financing Health: A proposed system to publicly finance a focused set of essential medicines, vaccines, and diagnostics for the 15 priority conditions. It includes: redirecting budgets toward these items, centralized pool procurement to ensure availability, and strengthening public and private supply chains.
  • Tobacco is Still the New Tobacco: Tobacco use remains the leading avoidable cause of premature death worldwide. Increasing tobacco taxation is deemed the most effective intersectoral policy for achieving the “50 by 50” target.
  • Pandemic Preparedness: The risk of another pandemic of Covid-like magnitude is high, with an estimated 20% likelihood within the next 10 years. Public health fundamentals, such as early case isolation, test-and-trace systems, and financial and social support during quarantines, are critical to mitigating deaths while awaiting vaccines.
  • Development Assistance for Health: External financial and technical support remains essential, particularly for countries with limited resources. Focus areas include disease control, pandemic preparedness, antimicrobial resistance (AMR), and developing new health technologies.

The report features notable Bay Area representation, with five of its 50 authors hailing from the region. Four of these contributors, including Dean Jamison (UCSF), Stefano Bertozzi (UC Berkeley and former Alliance board member), Shuchi Anand (Stanford), and Justina Seyi-Olajide (Lagos University Teaching Hospital and McGill) joined moderator Michele Barry (Stanford and Alliance board member), to share reflections of the report and explore how its messages can translate into actionable progress across global health.

Anand drew attention to the report’s premature death metrics, noting that a “30% probability of premature death for people under 70” reflects both a substantial challenge and a sign of progress in global health. She conveyed optimism, emphasizing that the report demonstrates advancements as a global health community.

Seyi-Olajide shared insights on reducing premature mortality by 50% by 2050, stressing that “focusing on 15 priority conditions, tailored to local contexts” could make this goal achievable. She underscored the importance of strengthening surgical systems, explaining that “surgery plays a key role in halving premature mortality” and should be prioritized within health systems. 

In thinking about the effects greater degrees of environmental threat and hazardous health exposures will have on NCDs, Anand noted that “chronic conditions are being amplified by climate change,” highlighting the effects that heat stress and lack of access to clean water can have on people with chronic conditions such as diabetes or kidney disease, particularly in lower-resource settings. 

Bertozzi reflected on the role of government intervention, citing the success of Covid-19 vaccine distribution as an example, “The public sector’s role in global health, especially during emergencies, is vital.” Regarding Covid-19 country mortality rankings,  Jamison observed that early in the pandemic, countries with strong public health and social measures, like Japan and China, performed well. However, he noted that the landscape had changed significantly by the end of the emergency period, with the virus’s transmission efficiency increasing and previously effective measures no longer providing the same results.

In thinking about how global health will change given the new administration, Bertozzi noted, “I think we have to play the hand that we’re dealt, not the hand we wish we were dealt. We have to look at opportunities, one of which is the difference between rhetoric and action,” sharing that the U.S. withdrawal from the WHO does not mean that the U.S. will stop collaborating with global efforts that are coordinated by WHO.

Jamison also emphasized that during their work on the commission report, there was a transition where they started to ask, “What are the messages for national governments and for regional organizations?” This indicated a shift in focus from national to regional actors, noting that “the decisions coming out of Washington are less important for countries,” with important actors, like the Africa CDC and WHO’s regional offices, becoming much more dispersed.

Reflecting on the path forward, moderator Neelam Sekhri Feachem (UCSF IGHS) was joined by Mike Reid (PEPFAR), Neha Agarwal (PATH), Thu Do (Gilead Sciences), and Tomás Aragón (California Department of Public Health) to share their thoughts on how to achieve the goal of “50 by 50”.

Reid pointed out how the new administration has been articulating an “America first” vision, so it is important to highlight how investments in global health can benefit both the U.S. and the world. “America’s contributions to global health can have a big impact, not just for Americans, but for people around the world,” he shared. However, he also emphasized the importance of countries taking more ownership of their health programs, especially those that have been traditionally funded by international donors, like PEPFAR. “Countries that have received sustained amounts of donor assistance need to be able to fund and respond to their own health needs,” stressing that strengthening local health systems is crucial for long-term success.

With the advancement of technologies, particularly artificial intelligence (AI), Agarwal shared that we should be cautiously optimistic and noted that leveraging AI has some tangible benefits. “The first fully AI-generated drug target just initiated phase 2 clinical trials,” she said. “AI is helping predict molecular structures and human targets, cutting down development time and costs significantly.” She emphasized that while AI isn’t the solution to everything, it’s proving to be a powerful tool in speeding up research and improving our response to global health challenges.

Do spoke about the importance of delivering innovations to the people who need them the most, especially in low-resource settings. “Most of the progress we’ve made in reducing child mortality has been due to new medical therapies,” she said. “But getting these therapies to the people who need them is just as important as the innovation itself,” stressing that access and delivery are key to making a lasting impact on global health.

In thinking about California, and the broader global health context, Aragón brought attention to the growing mental health challenges. “Mental health issues, whether caused by behavior, substances, or digital misinformation, are a major threat to public health,” he said, urging that addressing these challenges be a priority in public health efforts. He also emphasized that to build trust among communities and combat the effects of misinformation, it is important to be able to answer the four questions communities want to have answered: “Can I believe you? Do you care about me? Can you deliver? Can I count on you?” 

​​Looking toward the future, the panelists agreed that students and young professionals are the “50 by 50 generation” who will be key to driving these forward-thinking solutions. “The most effective solutions won’t be silver bullets. Most progress will come from well-designed partnerships. Young professionals should seek opportunities to work in diverse teams and embrace challenges to their assumptions using nuanced local evidence,” Do advised. 

In closing remarks, Address Mauakowa Malata (Malawi University of Science and Technology) stressed the need for leadership, collaboration, equitable partnerships, and prioritization of ownership and accountability, stating “As we move forward, as we reflect on this publication, we must look at what needs to be done at every level to ensure that 50 by 50 is achievable.”
