In a significant reshuffling of vaccine eligibility guidelines, California officials said Monday they will be shifting who is prioritized in the next round of COVID-19 inoculations to focus on age rather than specific occupations considered higher risk.

The modifications announced Monday by Gov. Gavin Newsom leave unchanged the current priority list, which focuses on healthcare workers and residents 65 and older before expanding to teachers, farmworkers and first responders.

But there will be shift in who gets the vaccine after them. Under the original plan’s tier structure, Tier 2 workers in manufacturing, transportation and commercial and residential settings along with incarcerated people and the homeless would be prioritized.

Under the new plan, the next priority would be people under 65 year old. No details about the criteria were released Monday, but it could end up focusing on people over 50 first.
