Global Paxlovid Access: Licensing, Coverage, and Testing Barriers
Paxlovid, an oral antiviral for COVID-19, has improved access in some low- and middle-income countries (LMICs) through a voluntary licensing agreement between Pfizer and the Medicines Patent Pool (MPP). This deal allows 95 LMICs to obtain affordable generic versions. However, many middle-income countries are excluded and must pay higher prices, limiting access for a significant portion of the global population. Additionally, the rollout of generics is delayed by bioequivalence testing, and limited COVID-19 testing capacity in LMICs further restricts effective use, as timely diagnosis is crucial for Paxlovid’s effectiveness. These barriers mean that only a small fraction of global COVID-19 diagnoses occur in countries with affordable access to Paxlovid, and many countries face high costs or limited supply .
Affordability and Cost-Effectiveness: Age, Vaccination, and Pricing
Research shows that Paxlovid is most cost-effective for older adults, especially those over 80, regardless of vaccination status. In China, for example, the current market price of Paxlovid is only justified for this age group. For younger or vaccinated populations, the price would need to be much lower to be considered cost-effective. The economic benefit of using Paxlovid increases with patient age and decreases with higher vaccination rates, suggesting that prioritizing older, unvaccinated individuals maximizes both health and economic outcomes 23. In the United States, the cost to prevent one hospital admission can be very high, especially as the risk of severe disease drops in vaccinated or previously infected populations .
Equity and Safe Access: Integrated Care Models
Efforts to improve equitable access to Paxlovid include integrated virtual pharmacy services, which streamline prescribing, dispensing, and follow-up, particularly for high-risk and marginalized populations. These models have proven feasible and effective, ensuring timely treatment within the critical five-day window after symptom onset and managing complex drug-drug interactions, which are common in patients with multiple comorbidities. Such approaches help address disparities in access and safety, especially for those disproportionately affected by COVID-19 .
Public Awareness and Demand: Communication Gaps
Despite its effectiveness, public awareness of Paxlovid remains low. In the US, a majority of adults have little or no knowledge of the drug, and many hold misconceptions about its effectiveness, side effects, and timing. These gaps are more pronounced among medically vulnerable and disadvantaged groups, who would benefit most from access. As government subsidies for Paxlovid decrease, improving public communication and outreach is essential to ensure those who need the drug can access it .
Societal Impact and Policy Considerations
Expanding Paxlovid use among symptomatic patients could prevent hundreds of thousands of hospitalizations and save billions in healthcare costs, especially during periods of high COVID-19 transmission. However, the greatest benefits are seen when the drug is targeted to those at highest risk of severe disease. Broad, untargeted use is less cost-effective and may strain healthcare budgets, especially as the price of Paxlovid rises and public funding wanes 67.
Conclusion
Paxlovid access and affordability are shaped by licensing agreements, country income status, and healthcare infrastructure. The drug is most cost-effective for older, high-risk, and unvaccinated populations. Integrated care models and improved public communication can help address equity and awareness gaps. Policymakers should focus on expanding affordable access, especially for vulnerable groups, and ensure that use is targeted to maximize both health and economic benefits 1234567.
