I had a go at digging up some research on the interplay between vaccination and vitamin D levels in protection against hospitalisation. So far I've found one study that touches on this: https://www.medrxiv.org/content/10.1101/2022.07.15.22277678v2 https://www.medrxiv.org/content/10.1101/2022.07.15.22277678v... . > Conclusions Among adults with sub-optimal baseline vitamin D status, vitamin D replacement at a dose of 800 or 3200 IU/day did not influence protective efficacy or immunogenicity of SARS-CoV-2 vaccination. This suggests that having the vaccine is still worth it even if you have normal vit D levels. So far I have yet to find any studies which show the opposite, but I'd be keen to read anything you can link.
