Drugs That Treat Pandemic Viruses

We already have drugs that treat the disease, so what's the urgency to find more? Well, we only have about a half dozen. Many of these antibodies have lost effectiveness against new variants. Even the new pill, pax lovit, has limits. It's good in people who are elderly or who have other risk factors but tests haven't shown a strong benefit for younger people. And they get seriously ill too, so we need treatment for them.
