  1. Vitamin D deficiency is very common.

  2. Randomised controlled trials showed that vitamin D decreases acute respiratory infections (ARIs).

  3. Vitamin D deficiency is an easily modifiable factor of ARIs.

  4. Daily vitamin D supplementation with moderate doses is safe and cheap.

  5. Even a small decrease in COVID-19 infections would easily justify this intervention.

Keywords: Covid-19; Vitamin D; coronavirus; respiratory infections.
