I cannot stress this enough, there is no cure. It will not happen, at least not in our lifetimes. This is a fantasy of yours. We should keep working on cures for viruses, but there has never been a successful cure for a virus. It just does not happen.
To find a cure for a bacteria, you simply have to find something different about the functioning of a bacteria cell to a human cell, and attack that spot. That is difficult, but doable. Cancer is more difficult, because it began as human cells. It does have differences like growing out of control. Most chemo attacks cells that grow quickly, like cancer, and (less fortunately) hair.
Viruses function as human cells. They take over the cell, but the cell functions the same as any other human cell. There is no obvious line of attack.
The immune system is able to attack individual proteins of the virus. That requires a machine that is so much smaller than anything we have available to us today.
To defeat viruses, we have vaccines, testing, tracing, quarantining, social distancing, masks, etc., but no cures.
