Vaccines are no longer our only medical intervention for preventing severe COVID-19. Over the past few months, we have seen the arrival and wider availability of treatments such as monoclonal antibodies (mAbs), and more recently, of novel oral antiviral drugs like Paxlovid and molnupiravir.
The recent Delta and Omicron surges have made these therapies scarce. The Delta variant led the federal government to resume control over mAb supply and promulgate allocation guidelines. The Omicron variant exacerbated scarcity because only one of the currently available mAbs, sotrovimab, appears to be effective against it. While Paxlovid and molnupiravir are effective against Omicron, both will likely be in short supply for many months. Paxlovid is currently constrained by a lengthy manufacturing process. Molnupiravir — which is substantially less effective — is contraindicated for use in patients under 18 and not recommended for use during pregnancy.
To allocate COVID-19 vaccines, the CDC’s Advisory Committee on Immunization Practices, the National Academies of Sciences, Engineering and Medicine (NASEM), and the World Health Organization (WHO) identified ethical goals for prioritization, such as maximizing benefit and minimizing harm, mitigating health inequities, and reciprocity. These committees, particularly the NASEM and WHO committees, included ethics experts as well as experts in social science, biology, and medicine. Current federal guidelines for therapy allocation, in contrast, do not identify ethical objectives or involve ethics expertise.
In an open-access Viewpoint in Clinical Infectious Diseases, we identify ethical goals for the allocation of scarce therapies. We argue that the same ethical goals identified for vaccine allocation–in particular maximizing benefit, minimizing harm, and mitigating health inequities — are also relevant for therapy allocation. Because many people have now taken steps to mitigate pandemic scarcity, for instance by protecting themselves through vaccination, we argue that reciprocity is also relevant.
