The district’s elected Board of Education will meet Thursday afternoon to vote on the measure, which is expected to pass with broad support. The Los Angeles Unified School District is the second largest in the nation, serving over 600,000 students, and the mandate could set an important national precedent.

Students would need their first vaccine dose by Nov. 21 and their second by Dec. 19 to begin the next semester fully inoculated. Those who turn 12 after those dates will have 30 days after their birthday to receive their first shot.

Students participating in in-person extracurricular activities will need both shots by the end of October. The resolution mentions “qualified and approved exemptions,” but does not offer details.

The district offers online independent study for those who opt out of in-person learning this year, but so far, only a tiny percentage of students have chosen it.
