Kinda depends, like antibody cocktails and standard care are what they are now after a year. Definitely has led to a reduction in actual deaths in comparison to the beginning of the pandemic and those may be able to be improved here and there. As far as some magic compound or anti-viral that is essentially take this pill and you will be good, very doubtful. Anti-virals like that for any viral infection are like the holy grail and may not even exist. Essentially the by the time you know you are sick the viral load is in the billions and its just too damn late.
But they're killed by ultraviolet light, right ?
