The program to address inequities in vaccine distribution relies on special access codes that enable people to make appointments on the My Turn vaccine scheduling website. The codes are provided to community organizations to distribute to people in largely Black and Latino communities.

But those codes have also been circulating, in group texts and messages, among the wealthier, work-from-home set in Los Angeles, The Times has learned. Many of those people are not yet eligible for the vaccine under state rules.

Some people able to make appointments have been driving to Cal State Los Angeles to get the shots.

It’s unclear how the codes got into the hands of outsiders, but the situation has forced the state to scramble to protect the integrity of an equity program that Gov. Gavin Newsom and other officials have been hailing. The state canceled appointments made with at least one of the access codes after The Times inquired about it last week.
