Challenges

  • Supply chain and shelf-life constraints: Long shelf-life antivirals are required by government stockpiling. The CDC’s Strategic National Stockpile report has stated that millions of oseltamivir doses expired and were wasted during the years 2021 to 2023, surging manufacturers to reform and extend the stability. For instance, the HHS required a heat-stable formulation from Tamiflu’s company in 2023, resulting in a delayed contract for six to seven months. Hence, manufacturers were facing various challenges to meet the stability standard risks and losing the long-term contract during pandemic preparedness.
  • Fragmented tender systems: Each region has different tendering structures and inconsistent bidding cycles for procurement procedures. This results in uncertainty in supply chains. In most low- and middle-income countries, procurement approvals and price evaluations tend to cause delayed deliveries and issues in inventory management. Such variability reduces manufacturers’ visibility on order volumes and delivery timelines, complicating production planning.  By contrast, harmonized and centralized procurement systems, like those introduced in segments of Europe, facilitate less complicated supplier coordination and more predictable market access.
