Mask wearing will be encouraged for the long haul even with a vaccine coming soon. More information is coming on the potential of asymptomatic spreading even with the vaccine.

Getty ImagesBOSTON - Lung damage in those using e-cigarettes might be caused by chemicals in the vape liquid, according to a letter published Wednesday in the New England Journal of Medicine. Researchers from the Mayo Clinic found the lung damage was similar to a chemical burn.

"Based on what we have seen in our study, we suspect that most cases involve chemical contaminants, toxic byproducts or other noxious agents within vape liquids," Larsen said.
