Los Angeles County public health officials at the various large-scale vaccination sites, including Six Flags Magic Mountain, are only administering second doses of the COVID-19 vaccine for the remainder of the week due to a “short supply of vaccines from the state.”

Since Tuesday, officials at county-operated large-scale COVID-19 vaccination sites have only been administering second doses of the vaccine, which L.A County health officials attribute to a “short supply of vaccines from the state” after receiving 184,625 doses of COVID-19 vaccines for the week.

This includes the vaccination site at Six Flags Magic Mountain, which has administered between 2,400 and 4,000 doses of the Pfizer COVID-19 vaccine each day since its opening on Jan. 19.

As a result of this vaccine shortage, officials say they are not taking appointments for first doses for the remainder of the week, even if a resident is either a healthcare worker or aged 65 or older.

Those who are arriving for a second dose must either have an appointment or be due for the second dosage, and provide documentation of their first dose with either a “white card” with the date of their first dose, a letter from the L.A. County Department of Public Health (LADPH), an electronic health record, or a confirmation email from their first dose.

On Friday, LADPH Science Officer Paul Simon announced that an estimated 1,051,229 doses of COVID-19 vaccines had been administered across the county.

“Because more people are being vaccinated we will be watching very closely to assess progress in ensuring equitable distribution of the vaccine,” Simon said at the time. “We already have a great deal of concern about people with more resources having better access to the vaccine — either because of their access to technology and information, their ability to spend more time getting an appointment or their ability to travel to other areas of the county.”

Just under 11% of all Los Angeles County residents aged 16 and over have received their first COVID-19 vaccine dose as of Friday, while only 2.6% of people in that same group had been fully vaccinated, according to Simon.

LADPH officials had not indicated whether or not they would re-open appointments for first doses next week as of early Thursday afternoon.
