Riboflavin + UV Light Effective Antiviral

[Peatogenic]

I remember a study posted here regarding methylene blue and red light being super effective in eradicating herpes virus. Here's a study showing something similar with a b-vitamin talked about here a good deal.

The Effects of Ultraviolet Light and Riboflavin on Inactivation of Viruses and the Quality of Platelet Concentrates at Laboratory Scale. - PubMed - NCBI

Do you think viruses can be avoided with certain measures like this, or is it more something that's effective after the fact?
