Your proposed title is so great that I have created an account after a decade of lurking! However, I must suggests what I consider to be a more correct formulation :
Genetic variants associated with vitamin D deficiency appear to be uncorrelated with the severity of COVID-19
I'm flattered, and I concur with your formulation being more accurate. I'd edit the title if I could, but at this point it looks like I'm not allowed to anymore. Would love to see the title updated if the mods see this!
