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

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

(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.

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.

 

Stay Safe and Healthy!

COVID-19

David Columbia Award May 2017Because the COVID-19 pandemic has affected everyone, including the brain injury community, I have added a new category called “COVID-19” to this blog. This category is for posting much-needed information and facts on the new coronavirus and the global pandemic it has caused.

The major reason I added the COVID-19 category is that I have unique access to a survivor of brain injury who is knowledgeable about this pandemic.

For 35 years, my husband, David, was a professor and did research in the Department of Microbiology & Immunology at Columbia University. He retired on September 1, 2013. In January 2005, David had a cerebellar hemorrhage. He survived a three-week

coma and three brain surgeries in the first two weeks of his coma. Unfortunately, he was left with many physical disabilities, but his cognitive brain was untouched, allowing him to return full-time to the faculty after 19 months. (Those 19 months are described in detail in my book Prisoners without Bars: A Caregiver’s Tale.) For 45 years, David did research on the molecular genetics of various microorganisms, including viruses.

02 Fork Yield Banner copyTo allow you to be introduced to David, I am reposting the link to my radio show of April 19, 2020, on the Brain Injury Radio Network called,  “Another Fork in the Road: BI Survivor/Columbia Prof Dr. David Figurski & Covid19.” (The link first appeared in my post on May 4, 2020.) David was my guest, and I interviewed him about his brain injury and about COVID-19. (Our discussion of COVID-19 begins at 49:50.)

New NEWS: Dr. David Figurski Speaks Out About Coronavirus

Dr. David Figurski Speaks Out About Coronavirus

David Columbia Award May 2017

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.

Coronavirus

 

 

 

Animal viruses, like coronavirus, probably take hours to reproduce, but each infected cell produces at least a thousand new virus particles.

Consequently, I have a healthy respect for viruses.”

David Figurski 2004 Pre-Brain Injury

David Figurski – pre-brain injury

My husband, David, bought a Catrike 700 in April 2015.  He rides three days each week, 15 miles each day. David loves his trike. Despite not being able to walk outside unassisted because of a balance problem, he feels “normal” when he rides. He has found that people have a lot of curiosity about the trike. People have stopped him to ask questions. One woman talked to him from her car when they were at a Stop sign.

David is excited because he just broke 2,500 miles. But he still has a ways to go before he equals the 5,390 miles ridden by Dan Zimmerman and Catherine Brubaker on their cross-country trek.

David’s cumulative mileage as of 10/13/16               2,580 mi

Miles to reach 5,390* miles                                          2,810 mi

UPDATE:

David’s cumulative mileage as of 09/04/117               3,727 mi

Miles to reach 5,390* miles                                          1,663 mi

*done by both Dan Zimmerman and Catherine Brubaker on their cross-country ride
