There were no formal eligibility rules because they didn't want to discourage people without IDs. The pastor did not open it up. Here is an article where he called people from outside the neighborhood "interlopers" and said he hoped word of the site wouldn't spread on social media: https://archive.is/Z55Oe
That quote was from someone at the office of emergency services, not the pastor. And the workers at the vaccine we’re telling people it was open to everyone 18+. I live here, this is information I got from talking to neighbors. There’s accounts on Reddit saying the same if you dig back in /r/oakland
You could argue that they shouldn’t have opened it up, or that every healthy person under 65 should have waited until supply was plentiful before trying to get one to not edge out any seniors or other at risk people, but there was no rule breaking or duplicity here.
I’ll also add that after this there were further targeted efforts towards getting shots to these zip codes. Someone in 94607 was eligible at most East bay sites weeks before CA fully opened up eligibility. I think this is what mberring is referring to, but it was a separate program from the vaccination site at the church.
