Vitamin D for Health: A Global Perspective (2013, positive): “Japanese children who received 1200 IU/d of vitaminD fromDecember through March compared with those who received placebo reduced their risk of influenza A by 42%.(186) It was also observed that children who took vitamin D daily had a relative risk reduction of 93% for having an asthma attack compare”

Evidence that Vitamin D Supplementation Could Reduce Risk of Influenza and COVID-19 Infections and Deaths (2020, background): “An RCT in Japan that reported no beneficial effect did not measure baseline 25(OH)D concentration [54] and included many participants who had been vaccinated against influenza (M. Urashima; private communication).”
Evaluation, treatment, and prevention of vitamin D deficiency: an Endocrine Society clinical practice guideline. (2011, background): “Japanese children who received 1200 IU/d of vitamin D from December through March compared with placebo reduced their risk of influenza A by 42% (82).”
Vitamin D—Effects on Skeletal and Extraskeletal Health and the Need for Supplementation (2013, background): “One of them showed as secondary outcome that vitamin D3 supplementation (1200 IU/day) in school children was associated with a significant 83% reduced risk for asthma exacerbations [218].”
The nonskeletal effects of vitamin D: an Endocrine Society scientific statement. (2012, background): “The first hint that cells of the innate and adaptive immune response in humans might be potential targets for 1,25-(OH)2D-directed gene expression and the subject of functional consequences regulated by vitamin D balance in the host came from observations of human immune cell populations in vitro: 1”
Vitamin D: The “sunshine” vitamin (2012, result): “[96] In a Japanese randomized, controlled trial, children given a daily vitamin D supplement of 1200 IU had a 40% lower rate of influenza type A compared with those given placebo; there was no significant difference in rates of influenza type B.[99]”
