On a personal note… WOOHOO! I’m getting the vaccine tomorrow!

NorthBay Medical Center giving vaccine to primary patients over 65

This is me, tomorrow! 🙂

UPDATE: This is me TODAY!  YAY!!!!  [January 26, 2021]

I switched to a primary care physician at NorthBay Medical Center last week, and received the invitation email today.  Signing up was easy, online, and I’m going in tomorrow for the Pfizer vaccine!

I’m so relieved and happy!

My spouse got the vaccine last week.  Her primary care doctor is in NorthBay, and both of us have seen multiple specialists there.  But my primary care doctor was with Sutter, who offered no good advice on how to get the vaccine.  Sooo…  On my own I discovered that Sutter is only offering vaccine to those over 75 – and last Tuesday I arranged to become a new patient with my spouse’s primary care doc at NorthBay.  And already today I got the email invite.


What Is Happening With the Virus in California? For Now, Many Mixed Signals

Monday: Hospital capacity is increasing in some areas. The vaccine rollout is still chaotic.

Good morning.

If you’re confused about the state of the virus in California, you’re not alone.

While California’s overall case numbers have been on the decline, hospitals in Southern California are still overwhelmed and experts worry that new variants of the virus — including one that researchers recently found in more than half of samples collected in Los Angeles — could threaten progress curbing Covid-19’s rampant spread.

In the Bay Area, intensive care unit capacity has risen to 23.4 percent, according to the state as of Sunday — well above the 15 percent threshold that triggered the stay-at-home order for the region. Yet the Sacramento area has just 11.9 percent intensive care unit capacity, and was allowed to exit the strict order more than a week ago.

Although The San Francisco Chronicle reported on Saturday that officials in the region were feeling hopeful that the order would be lifted soon, the state’s department of public health reported on Sunday that the Bay Area wasn’t eligible to have restrictions loosened based on its projections.

Gov. Gavin Newsom is expected to make an announcement about lifting some restrictions in the state on Monday.

The Associated Press reported that Mr. Newsom’s administration has refused to disclose key data that would help explain the difference in approaches between the Bay Area and Sacramento.

In any case, the state hinted in a news release on Sunday that Sacramento may be required to re-enter the stay-at-home order, which would force many businesses to shut back down. (We can expect to get an update from state officials in coming days.)

And even after President Biden unveiled what experts have long said is a desperately needed national strategy for finally controlling the pandemic, there are still major hurdles in the vaccine rollout, which in California has contributed to continuing chaos, in which vaccine eligibility rules have been implemented differently county by county.

As CalMatters reported, the state quietly rolled out a promised clearinghouse website to help people find vaccination appointments. But it’s still a work in progress.

California plans to independently vet COVID-19 vaccine data

State will assemble a “review board” of leading scientists

California will conduct its own independent review of potential COVID-19 vaccines, signaling its distrust of the Trump administration’s accelerated “Operation Warp Speed” initiative.

To vet a vaccine before distribution to state residents, California Health and Human Services Secretary Dr. Mark Ghaly said Friday that the state will assemble a “review board” of leading scientists at academic institutions to assess the safety and effectiveness of any vaccine candidate.

“We think it is an appropriate approach to take, especially because things are moving so quickly,” Ghaly said. “We want to make sure — despite the urge and interest in having a useful vaccine — that we do it with the utmost safety of Californians in mind.”

The announcement came at a press conference in which Ghaly also expressed concern that California’s coronavirus numbers are beginning to move in the wrong direction after weeks of declines. Based on current trends, he projected an 89% increase in COVID-19 hospitalizations over the next month. That would still be far below hospital capacity and the worst rates in other states.

On the vaccine testing issue, several other states, including New York, have signaled that they’ll also take the unusual step that Ghaly outlined.

“Frankly, I’m not going to trust the federal government’s opinion, and I wouldn’t recommend to New Yorkers, based on the federal government’s opinion,”  New York Gov. Andrew M. Cuomo announced at a Thursday news briefing, according to the New York Times.

President Trump has insisted a vaccine will be ready as early as next month, an assertion that other federal authorities say is unlikely.

California is already building a rollout plan for distribution of the vaccine, including whom to prioritize in the process, said Ghaly.

Led by the state’s Department of Public Health, members of a new Vaccine Task Force include other state agencies, as well as academic experts, community groups and individuals.

Once the state confirms the safety of the vaccine, this task force will advise distribution “in an equitable and smart way, to serve all the needs of Californians,” said Ghaly. “That absolutely is our plan.”

Conflicting information about the timing of the vaccine and whether it will be safe and adequately tested has created growing concern that people are hesitant to take it, despite its importance in stopping the pandemic.

The share of Americans who say they would get vaccinated for the coronavirus has declined sharply since earlier this year, according to a survey conducted this month by the Pew Research Center. About half of U.S. adults (51%) now say they would definitely or probably get a vaccine to prevent COVID-19 if it were available today, down from 72% in May.

Only about 21% said they would definitely get a coronavirus vaccine, half as many as in May.

While it is the federal government’s role to approve a vaccine, states have authority for actual distribution — and could, in theory, reject a vaccine they think is unsafe.

“Each state, indeed, has that sort of responsibility,” said Vanderbilt University’s Dr. William Schaffner, an internist and infectious disease specialist who formerly worked for the U.S. Public Health Service and the Centers for Disease Control and Prevention, at a Sept. 24 National Press Foundation program. “Some may be more ready to independently evaluate the data than others.”

An FDA committee — called the Vaccines and Related Biological Products Advisory Committee comprising 15 authorities selected by the FDA commissioner — reviews the safety and effectiveness data at a public meeting. The FDA commissioner usually follows the committee’s recommendation, but not always.

Typically, states follow the decision of the Advisory Committee on Immunization Practices, or ACIP, an independent committee that assesses data on FDA-approved vaccines and makes recommendations to the CDC.

But there is growing worry that the federal regulators may feel pressure from the White House to activate “Emergency Use Authorization” of an unlicensed vaccine, which would not require completion of a full “Phase 3” trial, during which efficacy is tested in thousands of people.

Two other COVID-19 products — hydroxychloroquine and convalescent plasma — received emergency use authorization, and have been touted by President Trump, despite little or no evidence of effectiveness.

This week, the FDA said it would enact new guidelines to toughen the process for approving a coronavirus vaccine. But President Trump said on Wednesday that the White House “may or may not” approve the plan, saying it “sounds like a political move.”

Saying they were “alarmed by political interference in science amid the pandemic,” the presidents of the prestigious National Academy of Sciences and National Academy of Medicine issued a statement on Thursday warning that “our nation is at a critical time in the course of the COVID-19 pandemic with important decisions ahead of us, especially concerning the efficacy and safety of vaccines.”

According to the Capitol Hill-based Roll Call, seven jurisdictions have indicated they would analyze the data independently: California, Colorado, the District of Columbia, Michigan, New York, Oregon and West Virginia. Another two — Montana and Wyoming — said they’d only administer a vaccine that completed clinical trials and an outside committee’s review.

“States are nervous. We’re talking about this now,” Marcus Plescia of the Association of State and Territorial Health Officials told Roll Call. “I think that a lot of public health officials in the states are concerned, given the rhetoric from the administration indicating they want a vaccine as quickly as possible.

But a state-by-state approach — for instance, if one state allows a vaccine, but another state does not — could complicate the pandemic response, which already varies greatly among states, said one expert.

While trust and confidence in the federal agencies has been shaken recently, “that is not the way to get control of this virus,” said Dr. Howard Koh, professor at the Harvard T.H. Chan School of Public Health, in a Sept. 16 media briefing. “Whenever a vaccine approval occurs, that needs to be accepted by the country, across the country, with implementation as a country.”

As to California’s numbers, Ghaly said Friday that the state is seeing upticks in case rates and hospitalization rates in some counties. They are small now but enough that the state is forecasting that 4,864 people will be hospitalized with COVID-19 by Oct. 25, an increase of roughly 89% from Wednesday, when there were 2,578 patients.

UCSF scientists: coronavirus immunity only temporary?

With coronavirus antibodies fading fast, vaccine hopes fade, too

Disturbing new revelations that permanent immunity to the coronavirus may not be possible have jeopardized vaccine development and reinforced a decision by scientists at UCSF and affiliated laboratories to focus exclusively on treatments.

Several recent studies conducted around the world indicate that the human body does not retain the antibodies that build up during infections, meaning there may be no lasting immunity to COVID-19 after people recover.

Strong antibodies are also crucial in the development of vaccines. So molecular biologists fear the only way left to control the disease may be to treat the symptoms after people are infected to prevent the most debilitating effects, including inflammation, blood clots and death.

“I just don’t see a vaccine coming anytime soon,” said Nevan Krogan, a molecular biologist and director of UCSF’s Quantitative Biosciences Institute, which works in partnership with 100 research laboratories. “People do have antibodies, but the antibodies are waning quickly.” And if antibodies diminish, “then there is a good chance the immunity from a vaccine would wane too.”

The latest bad news came from scientists at King’s College of London, whose study of 90 COVID-19 patients in the United Kingdom found antibody levels peaked three weeks after the onset of symptoms and then dramatically declined.

Potent antibodies were found in 60% of the patients, according to the study, but only 17% retained the same potency three months later. In some cases, the antibodies disappeared completely, said the study which was published as a preprint Saturday, meaning it has not yet been peer-reviewed.

The report is the latest in a growing chain of evidence that immunity to COVID-19 is short-lived.

A Chinese study published June 18 in the journal Nature Medicine also showed coronavirus antibodies taking a nosedive. The study of 74 patients, conducted by Chongqing Medical University, a branch of the Chinese Center for Disease Control and Prevention, showed that more than 90% exhibited sharp declines in the number of antibodies within two to three months after infection.

There is still hope that the remaining antibodies will bestow some immunity, but infectious disease specialists around the world were surprised and discouraged by the rapid reduction observed in the studies. If the numbers continue dropping after three months, it could mean people will be susceptible to infection by the coronavirus year after year.

So far, though, there have been only scattered reports of reinfection and no comprehensive studies have verified that it can happen. Experts say the disease hasn’t been around long enough to determine the likelihood of contracting the disease more than once. But other kinds of coronaviruses, like those that cause the common cold, offer clues.

Studies of four seasonal coronaviruses that cause colds show that although people develop antibodies, the immune response declines over time and people become susceptible again. Scientists suspect that the severity of cold symptoms is reduced by previous infections.

“Waning antibodies affect vaccine development,” said Shannon Bennett, the chief of science at San Francisco’s California Academy of Sciences. “Where natural immunity doesn’t really develop or last, then vaccine programs are not likely to be easily successful or achievable.”

Nobody knows yet whether infections by other coronaviruses will help people’s bodies resist COVID-19.

“Our understanding of protective immunity engendered by this virus and how it interacts with past immunity to other coronaviruses is still evolving,”Bennettsaid. “People should not presume they have immunity.”
