You don’t need to be hospitalized to get all the antivirals. In fact, that’s the whole thing paxlovid is supposed to prevent. Anyone with risk factors can take paxlovid, and it’s very effective at preventing severe covid. It should be started as soon as possible, not waiting until someone’s already hospitalized. Even in unvaccinated people, if taken early in the course, is 90% effective at preventing severe disease.
Remdesivir is the one that’s generally only for hospitalized patients, though even that can be used pre hospital too.
Anyways point is, if you get covid, and have risk factors for severe covid, call your doctor or urgent care to get paxlovid to take if you can, especially if you’re unvaccinated.
And yeah between getting diagnosed quickly, getting paxlovid I’m sure, and being immunized, Biden will very likely be fine.
