First sentence of the article seems out of place.
“Having low blood levels of vitamin D may not increase a person’s risk for severe COVID-19, a study published Wednesday by JAMA Network Open found.”
The rest of the article deals with succeptiblity to infection not severity.
I haven’t read the actual study yet to see if it’s just bad reporting.
“Having low blood levels of vitamin D may not increase a person’s risk for severe COVID-19, a study published Wednesday by JAMA Network Open found.”

“May”. One of the classic weasel words like “might” or “could”.
This is an incredibly meaningless article. Having high levels of vitamin D isn’t going to keep a virus from getting inside of you - it could affect how well your immune system responds as well as the severity of other symptoms. Antibodies would be present either way.
