California crossed a major threshold last week: For the first time, state officials moved to adopt a policy that that would give residents who are vaccinated access to different events and activities than those who aren’t.

New requirements for a “vaccine passport” — showing proof of vaccination to attend gatherings like weddings, conferences, concerts or theater shows — set California apart from states looking to ban such requirements and raise questions surrounding vaccine access and privilege in a region that has repeatedly failed to protect its most vulnerable populations.
