Here’s how California plans to distribute the COVID-19 vaccine in coming weeks
The vaccine requires two shots administered 21 days apart to reach 95% effectiveness. By year’s end, California expects to have given the first dose of the vaccine to 2.16 million people — health care workers, as well as residents of long-term care facilities.
With U.S. approval expected this week for the first COVID-19 vaccine, California could soon begin its historic and complex rollout of millions of immunizations, a much-anticipated turning point in a state where over 20,000 people have been killed by the virus.
Though it is unclear exactly when the U.S. Food and Drug Administration will grant approval to the Pfizer-BioNTech vaccine, the move could come as soon as Thursday, Gov. Gavin Newsom said this week.
California’s first shipment of vaccines will include 327,000 doses — supplying 327,000 people with their first dose — and is expected to reach hospitals between Saturday and Tuesday, he said.
The vaccine requires two shots administered 21 days apart to reach the 95% effectiveness established in clinical trials. By the end of the year, California expects to have given the first dose of the vaccine to 2.16 million people who are in the group that’s first in line — healthcare workers, as well as residents of long-term care facilities. Follow-up doses will come in further shipments.
“Hope is on the horizon,” Newsom said.
The milestone comes as the state anticipates a deadly winter. Most Californians are under a stay-at-home order as the state logs record numbers of new COVID cases and some hospitals begin to run out of beds in intensive care units. Already this year, 1.4 million Californians have been confirmed to have contracted the virus and 20,464 have died, a figure that will only grow in the coming weeks.
“The vaccine will not save us from this current national, state or local surge. Very simply, [there’s] not enough time,” San Francisco health director Dr. Grant Colfax said Wednesday.
For adults with COPD, what feels like a cold or lung infection, could actually be signaling a COPD flare-up.
Still, the approval of a vaccine represents a new phase of COVID-19, what some experts describe as the beginning of the end of the pandemic. On Tuesday, the United Kingdom became the first nation to administer the Pfizer shot to its healthcare workers and elderly.
In the U.S., a report by FDA staff released Tuesday confirmed that the Pfizer vaccine is highly effective and that there are no safety concerns that would prevent it from being granted emergency authorization. The findings set the stage for approval of the vaccine this week and the immediate availability of 6.4 million doses nationwide, which will be distributed to states based on their populations.
Once the vaccines arrive in a state, they will be stored at locations that can accommodate the extremely low temperatures they require — the Pfizer vaccine must be stored at around minus 70 degrees Celsius (about minus 95 Fahrenheit). Among these facilities are Cedars-Sinai Medical Center, UCLA and UC San Francisco Medical Center.
But a very small number of people will receive the vaccine this year, with the initial shipment to California “likely to end up largely in hospital settings,” Dr. Robert Schechter, a medical officer with the California Department of Public Health, told participants in a vaccine advisory panel Wednesday. Priority will go to health workers most likely to be exposed to the coronavirus.
Vaccines administered to residents and staff of long-term care facilities through a federal partnership with CVS and Walgreens will probably receive a separate slice of California’s allotment, rather than some of the first batch of 327,000 doses, Schechter said.
A second vaccine, created by the pharmaceutical company Moderna in partnership with the National Institutes of Health, could be approved by the FDA within a week of the Pfizer vaccine, Schechter said. California expects at least 2 million doses of it by the end of the month and approximately 6 million by the end of January, he said.
Beyond the two groups already designated most vulnerable, California officials have not yet determined who will be next in line for vaccines. Industry groups have lobbied for early slots for law enforcement, long-term care workers, the meat and poultry industry, the metal can industry, farmworkers and more.
For the general public not given special consideration, it will likely be spring or summer before vaccines are available, said UCLA epidemiologist Dr. Timothy Brewer. The initial allotment this year won’t even cover all 2.4 million healthcare workers in California, he said.
“If I were planning a wedding for next summer, I would plan it in a way so that everything is cancelable,” he said.
Brewer also said activities like nonessential travel may have to wait until after the summer depending on what’s learned in ongoing studies of the virus and vaccines. International trips could continue to pose risks longer, he noted, since other countries will need time to build up their vaccination programs, supply chains and infrastructure.
He said he anticipates the U.S. could reach herd immunity, with around 60% to 70% of the population vaccinated, by mid- to late 2021.
“I’m optimistic we will have a better Thanksgiving and Christmas next year than we did this year,” he said.
Statewide, the facilities where COVID-19 immunizations will be given will vary by place, Schechter said. California’s 61 local-level health departments are considering which institutions will provide the vaccines, but the scarce early doses will probably be limited to clinics and local health departments with public health sponsoring, he said.
“As the vaccine becomes increasingly available, this will feel more and more like receiving a seasonal flu vaccine,” Schechter said.
