Many will not agree (incl. doctors), BUT after much research and 'proof is in the pudding' I am a staunch believer in vits and immunity boosters that have saved us more than we can count! We take daily multi vits, Vit C, Cal/Mag., Fish oil or E. At the first sign of any cold, etc. we take Echinacea which is an immune system booster - 3x day for a week. Our son-in-law (a GI nurse) and family swear by Zinc. As not regulated, I would be very careful with children and hesitant to use any immunity boosters.
*I am not suggesting they would combat a virus of this type.
