A Los Angeles County health official Friday warned that getting an appointment for a shot will be initially difficult due to continued scarcity of vaccine supplies, but he said the situation will improve.
"We greatly look forward to this expansion, but want to remind everyone that its success will be dependent on receiving a substantial increase in vaccine supplies," said Dr. Paul Simon, chief science officer for the county Department of Public Health.
Gov. Gavin Newsom announced Thursday everyone 50 and over will be able to make an appointment to receive a shot starting April 1, and everyone 16 and older will be eligible starting April 15.

The vaccine eligibility expansion is based on the expectation there will be a significant increase in doses in the coming weeks. Newsom says there will be no limitations to get the vaccine, but there is still the limitation of supply.
The state expects to get approximately 2.5 million doses per week in the first half of April, and more than 3 million doses in the second half of the month.
L.A. County next week is actually set to receive its largely weekly allotment of vaccine to date -- 338,100 doses -- and tens of thousands more doses will be sent directly to other local vaccination providers, such as pharmacies and health care centers.
But when eligibility expands to those 50 and over on Thursday, it will add an estimated 800,000 to 1 million people to the pool of residents competing for limited doses. That's on top of the millions of people who are already eligible for the shots.
"There will undoubtedly be a rush come April 1," said Simon "... I want to make sure the public recognizes that there may be challenges to getting an appointment immediately. It just, again, reflects the limited supply of vaccine."

It was unclear when people in the newly eligible group will be able to start making appointments on the state's MyTurn website -- which is the main clearinghouse for appointments. Simon noted that there are also separate appointment websites for other providers, such as local pharmacies, and there was no specific timeline on when they would start accepting appointments for the new group.
The expansion of vaccine eligibility comes amid a reopening of more businesses. California health officials also gave the green light to reopen state theme parks in most counties beginning April 1 as long as the county is not in the purple tier.
Los Angeles and Orange Counties are currently in the red tier, meaning when Disneyland, California Adventure, and Universal Studios open, they'll be limited to 15% capacity. Six Flags Magic Mountain in Santa Clarita is set to open to members and passholders at limited capacity on April 1 and 2, and to the general public on April 3.
Meanwhile, the Federal Emergency Management Agency says after administering half a million vaccinations, it plans to close its two sites in the state on April 11, including the Cal State L.A. site. The county is looking to use it.
"We recognize it's a really important site," Simon said. "We in no way want to scale back vaccination infrastructure."

Kedren is also making sure vaccines don't go to waste. The clinics are using new vehicles to pick up expiring doses and then takes them door to door to homeless encampments and seniors in the area.
