That urgent desire for a sense of safety and a return to normalcy has fueled an unprecedented search for a vaccine against the worst pandemic humanity has faced in a century.
CEOs of Pfizer and Moderna, two of the vaccine developers furthest along in that search, have said they could request emergency-use authorization for their COVID-19 vaccines by late November and December, respectively, depending on results from trials that have enrolled tens of thousands of volunteers (including San Diegans).
