     Some things people need to know about vaccination and life after vaccination.

     If you’re healthy, you don’t need a booster, but it won’t hurt to get it. Donna and I will get the booster because we’re in the senior demographic, and our immune systems may have declined somewhat.

     Vaccinated people can get infected, but their disease will be mild or asymptomatic. There is no such thing as a “breakthrough infection.” All vaccines allow infection, but prevent severe disease.

Because vaccination doesn’t prevent infection, we definitely don’t want to infect any of the as-yet-unvaccinated children. We always wear our masks around children and try to keep a distance between them and us.

For the reasons I discuss below, virologists in my former department at Columbia say the vaccines will protect you from all the variants we know about – despite all the hysteria.

Columbia virologist Vincent Racaniello continues to emphasize that there are no data to support increased transmissibility of any variant. Delta might be widespread for any one of a number of possible reasons.

All the US vaccines are safe. Because of them, my fears of hospitalization and death are gone.

But we still may be susceptible to getting Long COVID (see below). (There aren’t enough data yet on whether vaccinated people can still get Long COVID.) The reason this is an issue is because Long COVID can apparently be brought on by a mild infection.

4i9pkz4ATEven though we’ve been vaccinated, we are still being careful. We try to mix with vaccinated people only. We try to avoid people and places that might be hot spots for infection. We only eat on restaurant patios; we never eat inside. We still practice social-distancing when we can, and we still wash our hands thoroughly and use disinfectant if we can’t wash our hands.

But we have also relaxed several things. Donna now goes into stores, but she always wears her mask. We’ve traveled by car, so we have stayed in motels. Although we don’t eat inside, we have walked through several restaurants with our masks on. Also, we’ve eliminated some precautions with our mail and our food packages.

You can stop here.

If you want more detail, the following is an easily understood explanation of what the vaccines do and why they’re so protective.

All the currently approved US vaccines are directed to one viral protein: the Spike protein. Spike proteins decorate the virus coat. They are responsible for allowing the virus to bind to a protein (ACE2) on the surface of lung cells. Because the viral-encoded Spike protein and the host-encoded ACE2 protein bind to each other, the virus can bind to the lung cell and get inside to start an infection. This means the lung cell will be hijacked and reprogrammed to make more virus particles. Each infected cell will release thousands of new virus particles. They can then attach to more lung cells. And the cycle repeats. You can easily see how a virus can quickly overwhelm its host animal.

(Incidentally, the Spike protein probably got its name because pictures (electron micrographs) of the virus show that it resembles a “mace,” a weapon used in medieval times. The head of the mace had spikes which did the damage. Similarly, the coronavirus particle is coated with “spikes.” They are made from trimers (assemblies of three copies of a single kind of protein) of the Spike protein. Coronavirus definitely got its name from pictures. Several Spike protein trimers on the surface of each virus particle make the virus look like a cartoon-drawing of the sun. The spikes on the virus look like the “corona” of the sun.)

Antibodies work by binding to the Spike protein and preventing the Spike protein from binding the lung cell’s ACE2 protein. As a result, the virus can’t bind a lung cell to start an infection.

All proteins are made up of a series of amino acids linked end to end. The Spike protein has 1273 amino acids. The sequence and types of amino acids (of which there are 20) determine the property and the folding of the Spike protein. The proteins are molecular machines. There are tens of thousands of different proteins in the human body – each one doing a unique job. The virus-encoded Spike protein is the viral machine that makes it possible for the SARS-2 coronavirus to infect lung cells.

Of the 1273-amino acids in Spike protein, only a few amino acids form the binding domain that allows binding of Spike protein to ACE2. Antibodies that bind to this binding domain of Spike protein inactivate the Spike protein and prevent the virus from infecting lung cells. Such antibodies are called “neutralizing antibodies.” The purpose of the vaccines is to stimulate the production of antibodies to the entire Spike protein, some of which will be neutralizing antibodies that can block infection. In other words, the neutralizing antibodies are a subset of all the antibodies produced that bind to the Spike protein. Because the Spike protein has lots of amino acids and lots of domains, it will stimulate lots of different antibodies that will bind the Spike protein, but only those that bind to the Spike domain that binds ACE2 are neutralizing antibodies. Only they will prevent the ability of the virus particles to bind to lung cells and get in.

The sequence of the 1273 amino acids in the Spike protein can also be seen as several smaller sequences of amino acids. Some small sequences of amino acids can fold properly and stimulate the formation of specific antibodies directed against that small domain. So most of the Spike-protein-specific antibodies bind the Spike protein at other places and do not block the ability of the virus to bind to and infect lung cells. The most relevant domain is the sequence of amino acids needed to form and fold properly so that Spike protein (and therefore the virus) can bind the lung cell’s ACE2 protein. Antibodies to that domain prevent binding of the virus to lung cells. These are the antibodies of interest – the so-called “neutralizing” antibodies. In fact, scientists are thinking of using only the amino acids that allow the proper structure of the ACE2-binding domain to form. If a vaccine can be made from the ACE2-binding domain only of the Spike protein, then maybe more neutralizing antibodies would be made, and the vaccine might even be better at preventing disease.

Some variants are known to bind the neutralizing antibodies less well. The virus has “seen” many vaccinated people, so there is “pressure” for the virus to change to ensure its survival. Some altered viruses randomly arise with slight changes, like differences in the amino acid used at a certain position of the Spike protein. (There is a reason why Nature allows DNA and RNA replication to make some random, but very rare, errors.) Some changed (=mutant=variant) viruses are still able to form a domain of Spike protein that can bind ACE2 yet evade some of the neutralizing antibodies that block the original Spike protein. Such changed viruses may do better and eventually become predominant. So random errors in replication can lead to viruses that have some ability to resist neutralizing antibodies, yet still bind to lung cells to start infection. These are what we are calling “variants.” Because the change increased the virus’ chance of escaping neutralizing antibodies, it survives better.  The arising of variants is evolution that we can see happening in real time.

But we got lucky! Some of the variants (like Delta) may escape some neutralizing antibodies. But we are still protected! The Spike protein also stimulates killer T cells, an important arm of the immune system that is usually ignored.

The killer T cell arm of the immune system is as potent as the more commonly known antibody arm. Not every protein has sequences that can instruct killer T cells, but Spike protein does. When a cell makes proteins, a small fraction of each protein being synthesized is chopped up, and small fragments of that protein are displayed on the surface of the cell. The immune system has a way to instruct a killer T cell to kill any cell making a foreign protein (that is, one not made by the human body). A killer T cell that has “learned” to recognize a fragment of Spike protein on a cell’s surface will kill the cell making it because that cell is considered to be making virus.

And that’s not all! The antibody arm of the immune system is less potent in the variants, but the killer T cell arm is completely unaffected. Not only that, but, whereas a variant resistant to the antibodies can affect an entire population, because of mechanism, it is impossible for a variant resistant to killer T cells to spread beyond a couple of individuals in the worst-case scenario.

Bottom line: All the Spike-protein-based vaccines we know about (Pfizer-BioNTech, Moderna, J&J, and the UK’s Oxford-Astra Zeneca) are protective beyond expectations. You’re safe if you’re vaccinated.

Donna and I recently celebrated 51 years of marriage.  We chose the beautiful desert scenery around the White Tank Mountains near our home in Arizona.  We returned to the place that Donna proposed to me last year as part of our 50th anniversary celebration.

This year, our anniversary celebration was very different.  We are in the middle of a global pandemic of a new coronavirus.  To slow the spread of this highly contagious virus, most people wear masks, practice social-distancing, and self-quarantine.  (For us, except for monthly food pick-up runs, we have been home over 160 days.)

Desert near the White Tank Mountains

The effect of the pandemic has been horrific and devastating for society, most notably for health-care personnel, blue-collar workers, teachers and school administrators, and middle- and lower-class families, who are struggling with paying bills, having enough food, and eviction.

Donna & David Figurski Wedding Anniversary #51

Globally, there have been over 22.5 million confirmed cases of COVID-19, and over 795,000 people have died. The U.S. has over 5.5 million cases and over 175,000 deaths. Scientists and physicians around the world are racing to understand the virus and its disease.  A viable vaccine is months away.

David & Donna Figurski – so happy together

Everyone is trying to cope as best as he or she can. On a personal level, Donna and I are fortunate to deeply love one another and to have each other in the midst of such chaos.

Love is worth celebrating wherever and whenever you can.

There is intense pressure from this Administration for any good news that might bolster its re-election chances. The government’s own FDA (Food and Drug Administration) might shorten the three required clinical trials that are key to proving the safety and efficacy of any vaccine before it’s approved for use by the public.

There is good reason to be concerned that government officials from this Administration might approve short-cuts to well-established scientific requirements because they want to speed things up. Both the FDA and the CDC (Centers for Disease Control & Prevention), two government agencies I have always trusted, have already bowed to political pressure from this Administration. The FDA approved hydroxychloroquine use for COVID-19 and later rescinded its approval when the drug was found to be ineffective against COVID-19 and to cause some dangerous side-effects in some people. The CDC, after feeling pressure from the Administration, revamped its back-to-school guidelines.

Dr. Vincent Racaniello – Columbia University virologist

Drs. Vincent Racaniello (virologist, Columbia U., host of the TWiV <This Week in Virology> podcasts), Brianne Barker (immunologist, Drew U.), and Rich Condit (retired virologist, Professor Emeritus, U. of Florida) discuss this issue in the TWiV podcast #631 of June 25, 2020. I urge you to listen to minutes 4:00-9:00. These three scientists talk about the importance of impartial and uncorrupted science in driving vaccine development and approval.

Also, an article about this issue can be found in the July 29, 2020, issue of HuffPost.

VaccineA legitimate way for the large Phase III clinical trial to end early is when the benefit is obvious. For example, if a vaccine candidate were given to 20,000 people and a placebo were given to another 20,000 people, the efficacy of the vaccine would be obvious (and statistically sound) if several hundred people in the placebo group became sick, while no person in the vaccine group became sick. Such an obvious result is exceedingly rare, and so, since it normally takes about eight months to do a Phase III clinical trial, if all goes well, we probably won’t have a confidence-inspiring vaccine until 2021.

COVID-19 — It’s Everywhere . . . Drug Breakthrough Significantly Prevents COVID-19 Deaths

Drug Breakthrough Significantly Prevents COVID-19 Deaths

Donna O’Donnell Figurski

 

(Disclaimer: The World Health Organization <WHO> has officially named the new coronavirus as SARS-CoV-2 and the disease it causes as COVID-19.

COVID-19

David H. Figurski, Ph.D & Survivor of Brain Injury

Research at the University of Oxford in England showed for the first time that a drug prevented a major fraction of deaths in severely sick patients with COVID-19.

Dexamethasone was found in a large clinical trial to cause a significant reduction in deaths. It can be prescribed as pills, and it is a common, readily available, and relatively inexpensive drug

A major problem after infection by COVID-19 is that the immune response of some individuals is too aggressive (often causing what’s called a “cytokine storm”) and can lead to death. Because dexamethasone is a steroid that dampens the immune response, the prediction was that it might help to prevent deaths by COVID-19.

The research showed that it does.

There are about 3 deaths for every 8 patients on ventilators.  Dexamethasone treatment reduced those deaths by one-third.  So, 1 death would be prevented for every 8 patients on ventilators.  About 5 deaths occur in every 25 patients on oxygen only. Dexamethasone treatment reduced those deaths by one-fifth, or about 1 less death for every 25 patients on oxygen only. Dexamethasone treatment had no effect on patients not on ventilators or receiving oxygen only.

Given that a major fraction of the over 118,000 deaths in the US so far (at 6:00 pm ET on June 18, 2020) were on ventilators or oxygen only, dexamethasone treatment is predicted to prevent many deaths.

The UK’s Chief Scientific Adviser, Sir Patrick Vallance, said: “This is a ground-breaking development in our fight against the disease, and the speed at which researchers have progressed finding an effective treatment is truly remarkable.”

COVID-19

David H. Figurski, Ph.D & Survivor of Brain Injury

 

 

I want to tell you about an amazing podcast, TWiV (This Week in Virology), created and hosted by Dr. Vincent Racaniello, a colleague of mine at Columbia University.

Vincent’s a virologist who has done cutting edge research on the molecular biology of influenza virus, poliovirus, and rhinoviruses (which cause the common cold). His podcasts feature several PhDs in microbiology (virologists, an immunologist, a parasitologist, and a science reporter who earned his PhD with Vincent) discussing the latest research and advances in viruses.

Vincent has been self-quarantining at home. Consequently, since March 13th, he has made more than 30 podcasts, nearly all concerning COVID-19, potential therapies and vaccines, and pandemics. His guests have been infectious disease scientists doing research or physicians in the trenches learning about the clinical manifestations of the virus and how to treat their patients.

Dr. Vincent Racaniello – Columbia University Virologist

Vincent’s podcasts are made for non-scientists to understand, but they are 1-2 hours long. Probably none of you has the time to listen that long. Therefore, I’m trying to listen to them so I can point you to episodes and minutes you may want to hear.

Podcast #622, released June 2, featured Dr. Emmie de Wit of the Rocky Mountain Labs in Montana. She’s a virologist doing drug and vaccine research in monkeys. Because Rocky Mountain Labs is one of the few places in the country with a high-safety-level facility, Dr. de Wit has worked with several dangerous viruses: SARS-1, MERS, pandemic influenza strains, and Ebola. Now she’s working with SARS-2.

I’ve boiled down Episode #622 to four segments totaling ~16 minutes.

  1. 26:05-26:35 – The spike protein of the virus coat initiates infection of a cell by attaching to the ACE2 protein (angiotensin converting enzyme 2) on the cell’s surface. Here Emmie tells how it took only days to identify ACE2 and confirm viral binding. Rich Condit, a virologist, was astonished by the speed. ACE2-binding by spike is a potential drug target.

 

  1. 37:15-39:44 – The PCR test (polymerase chain reaction), simple enough to be done on a large scale, detects the 30,000-nucleotide (or base) RNA chromosome of the virus. But, PCR is so sensitive that it can detect degradation fragments of the RNA, even though the person is no longer contagious. The only way to tell for sure is to detect viable virus in cell culture. This is hard to do and is only done in virology research labs. As a result, a person is considered infected and contagious if the PCR test is positive.

  1. 43:35-54:05 Remdesivir, an antiviral drug, is a nucleotide-analog that blocks the copying of the RNA chromosome to make more virus. Emmie showed that giving remdesivir to monkeys early (at 12-hours post infection) was very effective. But, humans don’t show symptoms for days, and, because remdesivir must be administered intravenously, patients are only given remdesivir if they are hospitalized. This is very late, and still there is a modest effect. Rich Condit talks about the possibility of producing an oral form of the drug. Then remdesivir could be taken earlier – maybe even at home – and might be very effective in humans.

 

  1. 58:25-60:40 This segment concerns a vaccine. (I’ll write more on this topic later, but you should know that there are three types of promising technologies: the viral protein-based, the viral gene-based, and the virus vector-based, in which a harmless virus carries a gene from a disease-producing virus for a protein that’s needed to infect cells.)2ff087415a5009984739aa8fde5d5d4a

Emmie tested a harmless chimpanzee adenovirus that was engineered to carry the COVID-19 spike gene. This adenovirus produces the coronavirus spike protein, needed for COVID-19 to infect cells. So, this harmless adenovirus should cause us to make antibodies that will block infection by COVID-19.

In Emmie’s experiment in monkeys, the vaccine worked so well that it allowed clinical trials to proceed in humans.

COVID-19 — It’s Everywhere . . . Vaccine is Possible

COVID-19 . . . Evidence that a Vaccine is Possible

by

Columbia University Professor Emeritus, Dr. David Figurski

presented by

Donna O’Donnell Figurski

 

(Disclaimer: The World Health Organization <WHO> has officially named the new coronavirus as SARS-CoV-2 and the disease it causes as COVID-19.  Because the majority of people, including much of the press, commonly refer to the virus as “COVID-19,” to avoid confusion, I use COVID-19 as the name of the virus in these posts.)

COVID-19

The 100+ labs trying to develop a vaccine for COVID-19 were delighted with a study showing that COVID-19 stimulates a strong antibody response in humans. Scientists from the University of California at San Diego (UCSD) demonstrated that a vaccine for COVID-19 is definitely possible.

The scientists studied blood from mildly sick individuals who recovered. They found a high level of antibodies to the spike protein, used by COVID-19 to infect.

The strong antibody response suggests that immunity will occur in humans and will last a while, but no one knows for how long – weeks? months? years?

The scientists were surprised by another result. For you also to understand it, I have to give you some background. (Sorry!)

There are seven coronaviruses that infect humans.

Four are common and cause mild, cold-like symptoms.  We’ve all probably had one or more of these.

Three coronaviruses (SARS-CoV, SARS-CoV-2 <which causes COVID-19>, and MERS- CoV) cause serious human disease and some fatalities.

Blood taken before COVID-19 even existed in humans nevertheless showed the presence of antibodies that reacted with COVID-19.  Infection with one of the mild coronaviruses may have stimulated the body’s production of some antibodies that cross-react with COVID-19.

Some seemingly healthy individuals have died from COVID-19. In contrast, some people not predicted to do well had mild disease or were asymptomatic. Doctors are perplexed by their inability to predict who will recover.

David H. Figurski, Ph.D & Survivor of Brain Injury

One possibility is that the amount of cross-reactive antibodies arising from previous infection with one or more of the mild coronaviruses may determine how well a COVID-19-infected person will do.

Professor David Figurski        Columbia University College of Physicians &Surgeons

 

“In graduate school, I worked with a virus that infects bacterial cells (bacteriophage T1). One T1 virus particle takes about 10-12 minutes to break open the E. coli cell and release over 100 new virus particles. Each new particle can infect a cell and produce over a hundred new virus particles. So, 10-12 minutes later, there are 10,000 viruses. I could do some experiments in the morning and have the results that afternoon.

To make stocks of the virus, we would infect a late culture of bacteria. A couple of hours later, all the bacterial cells were broken open, leaving only virus.

Common Mouse Cell Type Converted to Neurons

presented by

Donna O’Donnell Figurski

 

newsboy-thCommon Mouse Cell Type Converted to Neurons

You’ve probably heard of the promising future of cell therapy. The excitement comes from the fact that injuries might be treated by implanting fresh, healthy cells. Stem cells, which can mature to many different cell types, have been discovered in almost every organ in the body. They hold enormous potential for helping to heal injured organs. Already, scientists are devising methods to add new muscle to damaged hearts and to add insulin-producing cells to the body to cure Type I diabetes. The brain also has stem cells, and much of the natural recovery from brain injury is due to stem cells, which rebuild the damaged part of the brain. The beauty of stem cells from the brain is that they can develop into healthy neurons and replace damaged circuits. But the natural healing of the brain is often insufficient. Scientists have been looking for ways to make more stem cells and to activate them so that implanting them is practical and they can result in more healing.scientist

I want to tell you about exciting basic research on cell therapy that may make possible or speed up the development of new therapies for brain injury. Scientists at Duke University have found a way to make neurons from common mouse cells, called “fibroblasts,” without resorting to stem cells. The scientists made a modified protein and put it into fibroblasts. The modified protein found and activated the master regulator genes needed to turn on the genes for the cell to become a neuron.

In the past, a cell’s change into a neuron required that extra copies of the master regulator genes be introduced into the cell. The cell maintained its neuron-like properties only if the extra activators were present. If the extra copies were lost, the cell reverted to its original form. Scientists said that the neurons were “unstable.” Still, it was a breakthrough. To help stabilize the neurons, extra copies of genes for the master regulators were added to its chromosomes. The neurons still weren’t perfectly stable, and the presence of extra copies in the chromosomes was unnatural.

In the new method, activation of the neuron genes is natural. The neurons are “stable,” even when the modified activator protein is gone. As far as the scientists can tell, the neurons formed this way appear to be like natural neurons.

MouseOf course, these studies need to be done with human cells. But, because the mouse is similar enough to humans genetically, new neurons are likely to be made from human cells. If so, cell therapy to treat brain injury will become common in the foreseeable future. One benefit is that therapy can be personalized. It’s not practical to get your neurons from a brain biopsy, but your easy-to-get fibroblasts can be converted to neurons. Those neurons can then be tested with therapeutic drugs to see what works best with your genetic background. Also, the implanted cells would not be rejected by your body (prevention of rejection is the reason for immunosuppressive drugs today) because the neurons would be made from cells of your own body.

Grief After Brain Injury

images-1Grief is often an after effect of brain injury. It is experienced not only by the survivor, who may have lost his or her “old” self and is trying to adjust to his or her new world, but also by those who have frequent contact with the survivor. As we know, brain injury affects ALL members of the family, who are often the caregivers.

Panelists, Sandra Williams (both survivor and caregiver), Dr. David Figurski (survivor), and Lisabeth Mackall (caregiver) joined me to discuss the topic of GRIEF. We examined the feelings of the family as they adjust to their loved one’s change, as well as discussed the stages of grief as outlined by Dr. Elisabeth Kübler-Ross in her book entitled, “On Death and Dying.”
