With high winds and elevated fire danger in the forecast, the COVID-19 vaccination site at Disneyland will be closed Tuesday, dealing a temporary blow to efforts to accelerate the distribution of vaccines.

The Orange County Health Care Agency announced the closure late Monday, citing “high wind warnings issued by the National Weather Service for Orange County.”

People who had appointments to receive vaccinations at the site on Tuesday will be notified of rescheduled times, according to the agency.

Due to the Martin Luther King Jr. holiday, the county did not release updated COVID-19 case numbers on Monday.

Entering the day, the county had reported a cumulative total of 210,813 infections since the pandemic began, along with 2,367 fatalities.

Hospitalization numbers continued to dip over the weekend, dropping to 2,026 Sunday — down from 2,065 on Saturday, 2,101 Friday and 2,169 Thursday, according to the OCHCA. The number of coronavirus patients in intensive care decreased by four to 538, a slight reduction from last Sunday’s record of 547.

Of the 47 deaths reported Sunday, six were skilled nursing facility residents, and eight were residents of assisted living facilities. Since the start of the pandemic, the virus has killed 730 skilled nursing facility residents and 259 assisted living facility residents.

The death reports are staggered and sometimes take weeks to be logged, but December was the deadliest month for the county since the pandemic began, with 538 fatalities recorded so far from that month. That tops the summer peak, when 379 died in July and 367 in August, according to OCHCA statistics. The deadliest day so far was Dec. 22, when 32 died.

The Orange County Sheriff’s Coroner’s Department has had to provide trailers with freezers to store an average of about 100 bodies until funeral homes can catch up and take them, Orange County CEO Frank Kim said.

The county’s state-adjusted ICU bed availability remains at zero, and the unadjusted figure decreased from 7.8% Saturday to 5.5%. The state created the adjusted metric to reflect the difference in beds available for COVID-19 patients and non-coronavirus patients. The county has 36% of its ventilators available.

The Southern California region remains at zero ICU availability.

The 25,761 test results reported Sunday raises the cumulative total to 2,430,704. There have been 136,506 documented recoveries.

Orange County’s adjusted daily case rate per 100,000 — released on Tuesdays — increased to 78.8 from 67.8 last week.

The county’s Health Equity Quartile Positivity Rate, which measures the cases in highly affected, needier parts of the county, rose to 24.2% from 23.4% last week.

The county’s seven-day positivity rate is 19.5%. Testing demand is also slowing, while the demand for vaccinations is soaring. Officials do not expect a significant drop in hospitalization rates until at least the end of January, Kim said.

The county’s Othena.com app and website, where residents can get vaccination information and make appointments to get inoculated at the Disneyland mega-site that opened Wednesday, have been heavily used since going online Tuesday. The website hits and downloads of the app topped 100 million combined this week, Kim said.

The county on Thursday opened up 3,600 appointment slots for Sunday, and they were all taken in 13 minutes, he said.

On Friday, some of the residents being inoculated at Disneyland were given a ticket so staff could track how long it took them to get through the process. What was taking an hour or two on Wednesday was down to 42 minutes on Friday, Kim said.

“I was really happy we got it under an hour,” he said. “That means we can start increasing capacity.”

The county will hire about 120 temporary workers to help with staffing, Kim said. Another team is working on recruiting and screening volunteers.

Officials are also working out the bugs on the app, adding that a new version awaiting Apple’s approval is expected to address the most common concerns and issues.

“We think the majority of the issues are behind us now,” Kim said.

Dr. Clayton Chau, the county’s chief health officer and OCHCA director, said seniors 65 and older were moved to the front of the line for vaccines this week, immediately following the state’s modified guidelines. He noted that a survey showed 54% of the COVID-19 patients hospitalized in 13 OC hospitals are 61 and older and 71% in ICUs are 61 and older. Nearly 72% of those on a ventilator are 61 and older.

“Seventy-five percent of those who have died in Orange County are also seniors, aged 65 or over,” Chau said Tuesday.

Monday, the OCHCA reported a concern with one lot of the Moderna vaccine — suspending use of Moderna’s lot 041L20A due to possible allergic reactions that are under investigation by the Centers for Disease Control and Prevention, U.S Food and Drug Administration and the manufacturer.

The agency said that, to date, it has received zero notifications of allergic reactions requiring medical attention due to any Moderna vaccines.

“According to the state vaccine registry, 5,217 individuals in Orange County received the Moderna vaccine lot 041L20A,” the county said. “To determine if you received the subject vaccine lot, please refer to your vaccination card. If you received a vaccine from this lot number and experience any adverse reactions or don’t feel well, please immediately contact your primary care provider/doctor.”

For the past two weeks, the county has set up pop-up clinics to bring vaccines to “high-density pockets of seniors” in the community, Kim said.

Orange County expects to spend between $60 million to $70 million on the Super POD vaccine sites, he said. Ultimately, the county wants to have up to five of the mega-sites and to place them regionally throughout the county with the next one either on the north end or the south end.

But first, the county wants to stabilize the Disneyland site and have enough trained volunteers committed to staffing it before opening a second one, which would be backfilled by staff in case volunteers do not show up for work.

Also, the county needs enough supply of vaccines to justify opening another site, officials say.

The county is expecting 35,000 more doses this week, Chau said, and is handling distribution of about 20% of the doses sent from the state, with health care providers doling out the rest.
