Moderna (NASDAQ:MRNA) has become a household name this year thanks to the rapid speed with which it has been developing and testing its COVID-19 vaccine candidate, mRNA-1273. The stock has also been a big winner, soaring more than 300% so far in 2020.  But it's far from the only company attempting to develop coronavirus vaccine, and one far less well-known biotech in the hunt has seen its share price climb almost as much as Moderna's.

It's a possibility, according to a new paper from researchers at the University of California - San Francisco and John Hopkins, which will be published in the Journal of General Internal Medicine. The paper draws on "virologic, epidemiologic, and ecologic evidence" to make the argument that wearing a face mask could result in a lower "viral dose," or amount of coronavirus particles, taken in by a wearer exposed to the virus. And according to several studies cited by the re...
