This idea of rationing antibodies with a preference for those who are not vaccinated makes sense medically as those who are vaccinated are far less likely to have a severe case of covid.
The vaccinated people dying of breakthrough cases in my area (Southern Oregon) are the elderly, most of whom were vaccinated in January/February. Elderly immune systems are less robust as you know, even vaccinated. Combine that with the immunity wearing off now, and the vaccinated elderly have just as much need for the monoclonal antibody treatment as a younger person who refused to get vaccinated IMO. Of course, some of those younger unvaxxed ones feel that the elderly are expendable for their convenience, but I know you don’t feel that way. Those of us who are heading toward 80 and behaved responsibly should not be deprived of monoclonal antibodies when a breakthrough case can kill us. JMO MOO
