Even for those eligible, it has been difficult to navigate the various coronavirus vaccine sign-up, notification, and appointment systems. In response to the disjointed publication of information from various clinics, providers, and governments, a group of volunteers with some technical know-how got together to build a statewide resource for finding vaccine appointments. What began as a spreadsheet is now a website, VaccinateCA. Zoelle Egner, one of the co-organizers of VaccinateCA, and Carroll Lachnit, a phone banker for the project, talk about how it works and how it's unfolded.
