 perhaps keep you out of a hospital, which is important. But it seems to me that this should be used in tandem with mask wearing, especially in crowded public spaces. And I found that has been just thrown out the window. I'm a member of Kaiser, and I go down there in Kaiser Hospital, and a lot of the employees aren't wearing masks, and most of the patients aren't. A lot of these people are sick people. I've seen the people coughing.
