Or perhaps if you are actively drinking tea and possibly rinsing your nose with it, it will protect you from infection to a decent degree? The study is showing a good deal of virus inactivation from the levels of tea that might be present in saliva 0 minutes after drinking tea. But not such an extreme degree of inactivation that it seems at all likely that residual levels of the active ingredients an hour later would be likely to help much.
