California will be mandating statewide vaccinations for schoolchildren, becoming the first state to incorporate such legislation.
The news was announced by Californian Governor Gavin Newsom at a news briefing at a school in San Francisco.
The Food and Drug Administration (FDA) must fully approve vaccinations for this age group first.
Certain schools in the state have already mandated the vaccine for some students.
In the Los Angeles Unified School District, children over the age of 12 are required to get vaccinated, with the FDA authorising their emergency use.
All public schools in San Diego will require students over the age of 16 to get vaccinated in December, while Hoboken in New Jersey will either require students to get vaccinated or undergo weekly testing for the virus.
