LOS ANGELES (CBSLA.com) — The Los Angeles Unified School District will not allow students to start class if they have not received the required vaccinations. There will be no grace period.

“All schools are instructed to stop families at the door as they’re enrolling and to ask for immunization record,” said LAUSD Nurse Administrator Roberta Villanueva.

California’s new law, SB 277, which took effect July 1, requires all students in private and public K-12 schools to be fully immunized.

“Families that do not comply with the one-size-fits-all vaccine mandate will lose their state constitutional right for a free and appropriate education,” according to the SB 277 website.

Medical exemptions are allowed but not those based on personal beliefs.

Shots are free for those with Medi-Cal and no insurance. Families with private insurance will have to go to their pediatricians.
