I don't think 400 IU is going to do much. 5000 IU of D3 daily is going to get your level close to what indigenous people's are and more in line with what our evolutionary biology wants. A study was done in 2012 that measured this and these tribal peoples' mean vitamin D level was 115 nmol/L which translates to about 44-45 ng/ml. 5000 IU will get you there, presuming you have little to no exposure to actual sunlight. So probably adjust that 5000 down during the sunny season or if you spend a lot of time outdoors. Vitamin D toxicity is believed to occur above 100 ng/ml, so there's a lot of leeway, although I'm not familiar with where that limit comes from, so the truth may be lower or higher.Vit D really is a near miracle with respect to corona. Even those with the pre existing conditions and obesity who get adequate sun and/or 400IU supplements have a *much* lower risk of serious disease, death and lingering long term issues.
Now ask yourself why Biden, the CDC, the Media isn't telling Americans to up their Vit D blood levels.

Vitamin D Insufficiency May Account for Almost Nine of Ten COVID-19 Deaths: Time to Act. Comment on: "Vitamin D Deficiency and Outcome of COVID-19 Patients". Nutrients 2020, 12, 2757 - PubMed
Evidence from observational studies is accumulating, suggesting that the majority of deaths due to SARS-CoV-2 infections are statistically attributable to vitamin D insufficiency and could potentially be prevented by vitamin D supplementation [...].pubmed.ncbi.nlm.nih.gov
Now think for a moment as to why microbes cause infection far more in the winter than warmer months. The usual answer is people go outside. But they really don't. The same crowd is in the office, store, train, church in the same way all seasons.
However, people do get far more sun and vit D in the warmer season.

As for the seasonality of respiratory infections, I'm right there with you that D levels play a major role. I think humidity and UV penetration of the ozone might also be at play, too.
