“If that were effective in preventing flu, nobody would have the flu except for those who never come out except at night.”

Ok. Good point. I just figured that since many people get low on their vitamin D in winter, perhaps the “low-D” people are more likely to get it. Hence, an extra effort to get outside might be beneficial.
Other question: how much milk/fish/dairy would you have to drink to get 2000 IU per day?
Also, are you suggesting taking that dose every day until the flu crisis passes? Are there any side effects from that dosage?
Also, it was shown that kids in Arizona, I believe, were still deficient in D even with relatively generous sun exposure year round. It still wasn’t enough. Not sure about full-time nudists in Florida. Taking D3 supplements makes more sense for most of us. I take 2,000 IU/day, but the injectable form can be up to at least 50,000 IU, given weekly.
