Have you looked into getting monoclonal antibodies (Regeneron)? My understanding is that you have to get them within the first 10 days of symptom onset in order for it to work.
My doctor has encouraged me to do so, but my research indicates that all monoclonal antibody treatments also used cell lines from aborted fetuses in their testing. So that’s a red line I won’t cross, come what may.
I don’t think you can get Regeneron anymore- Biden pulled it in January limiting it’s use to NON Omicron variants, and since no one is variant tested, that essentially stopped it’s use.
