They are very different viruses and you can make a vaccine pretty easily - but ensuring it is effective is another story.

HIV is a retrovirus that writes itself into your immune cells. Once you have it - its always running and you have to constantly throw monkey wrenches into its machinery to keep it from getting an edge on your immune system. But its constantly evolving and trying to outpace your immunity.

The Wuhan Flu is not a retrovirus so you can be cleared of it -- but it has a capsid and receptor set your immune system is completely foreign to --- but it has keys to your cells. That is why its so bad. Your immune system does not know you are sick until they start blowing up cells.
