When I read stuff like this I like to ask the questions following questions, and I suggest that you do so also of your sources: Where did you get this information? How did you come to these conclusions?
From what I've read stage 2 trials are very promising for a couple of vaccines. Researchers are showing a high degree of immune response in the blood. Now it needs to be tested in real life but their confidence levels are high.
COVID-19 is very different from an influenza virus, which mutates extremely quickly. The mutations in COVID-19 have been small and are not expected to affect how well a vaccine works. SARS-1 actually had work started on a promising vaccine, but funding dried up when the disease disappeared.
Here's a legitimate website on what treatments are being researched. This website only cites legitimate medical sources and peer-reviewed journals:
