DR. NICOLE SAPHIER (FOX NEWS MEDICAL CONTRIBUTOR): Now, we don’t have good data when it comes to delta, we know it's much more contagious, and it’s causing higher viral loads. So, it's likely Delta would probably cause more symptoms in children than maybe some of those earlier strains. But until we have something showing us that COVID-19 is — can cause severe illness in children, I think the benefit of children wearing masks really does not outweigh the risk of these young children, less than 14, wearing masks all day. I think it's important to remove masks from them. At this point, any adult can get vaccinated, and they can still wear high-grade medical masks to further their protection if they so choose.
