1. A doctor in Boston developed a reaction to Moderna. Doctor was allergic to shellfish.
2. US promised to roll-out vaccine to 20 million by the end of the year. We only have about two millions so far (in two weeks.) It’s going slow.
3. 11.4 Million doses have been sent out to various centers in the US.
4. There is possible lag of reporting, but, that will not be in millions.
5. CDC requires two days of vaccine quality assurance when it reaches its destination before its administration.
6. End of the first week is the target. I have been saying that all along.
7. Moderna has started shipping as well. More than 3,500 centers will receive Moderna compared to about 600 centers for Pfizer.
8. Most of this seems to be logistics. Brining the vaccine, quality assurance, allocating staff to administer the vaccine. And, to assign personnels to get the vaccines.
9. In some states the vaccines are becoming available for the long term care facilities, but, still not injected as efficiently.
10. When a dose is given to someone, a dose is kept in reserve for their second shot.

https://www.youtube.com/watch?v=m9mrJIiHOb4&ab_channel=Instinct-IntegratedIsraeliCombatives

Vaccination started on Dec 20th 2020
More than a million people have received both shots.
More than 2.6 million people have received one shot.
After the high risk folks, Israel is now administering vaccine to over 40 and high school students to enable them to go back to school.
Military reserves are helping with the rollout.

Results are biased because the people receiving the vaccine are already more careful of their risk and better informed.

Israel is leading the world in vaccination
Population of Israel is about 9.3 millions (reference: https://en.wikipedia.org/wiki/Demographics_of_Israel)
Israel has administered 3.9 million doses. (More than 40% of the population.)
42.92 doses for each 100 people. Best in the world so far.
More than 75% of its older population is now vaccinated at least with one dose.

Israel’s COVID situation
https://www.worldometers.info/coronavirus/country/israel/
613,578 cases
4,512 deaths

Wave three is going on. Strict lock downs are in effect.

Israel signed a contract with Pfizer to provide vaccination data in return for an early and a steady supply of the vaccine doses.
Here is the redacted version of this contract: https://govextra.gov.il/media/30806/11221-moh-pfizer-collaboration-agreement-redacted.pdf

Preliminary findings:
Over 12,000 people test positive for COVID-19 after receiving Pfizer vaccine
https://www.wionews.com/world/israel-over-12000-people-test-positive-for-covid-19-after-receiving-pfizer-vaccine-358242

Initial data by Clalit (Israel’s largest health fund.)
200,000 people 60+ administered the first dose.
14-18 days after the first dose, partially vaccinated were 33% less likely to be infected compared to the similar cohort that are not vaccinated.

Maccabi’s research arm data
430,000 people’s data
13-21 days after the first shot 60% reduction in infections.
For 50,777 people vaccinated
On day 23rd (two days after the second shot,) 60% drop in hospitalizations.

On Monday (Jan 25th 2021) Israeli health ministry and Maccabi released new data.
Out of 428,000 people vaccinated
A week after only 63 people (0.014%) were infected.
Out of 128,000 people that are vaccinated.
A week after only 20 people (0.01%) were infected.

“Don Phelps • 2 hours ago
Dear Dr, There has been published recent update on AstroZenica vac.
The different efficacy rates turned out to be due to time interval between first and second shot, and delay period before efficacy measured. I belive I saw it WhiteBoard Doctor. But I also watch TrialSiteNews and medcram. So please update your review. Hope that is helpful. I do love and appreciate you and this channel. Yours, Don”

Vitamin D Cuts COVID Deaths by 60% Watch Now (26:10)

Errata: I said vitamin C in the beginning, it should have been vitamin D.

New Study from Barcelona Spain finds that Vitamin D could reduce the risk of COVID deaths by 60%

Here is a vitamin D study from Barcelona. With, great results. Takeaway is that the baseline levels of vitamin D should be correct in all of us. It improves our chances of survival and could reduce the risk of severe disease and death by 60%.

Also, soon at the admission in a hospital correcting the vitamin D levels is crucial. Authors found that the vitamin D levels corrected in the ICU did not have a large impact compared to the levels corrected earlier in the wards.
However, there are certain limitations of the study that are reducing its impact.

Some limitations:
It is not really an RCT. Instead it is some sort of possibly random cluster trial.
Study seems to change protocol of the Vitamin D administration.
Study is not in the study registry for some reason.
Authors say that it is an observational open randomized trial. While they write it as an RCT.
Still the results are in line with the way vitamin D’s effect should be.

COVID Long Hauler Watch Now (24:17)

COVID Long Hauler (Symptoms and Management)

Possible causes
Is it because of the persistent virus or slow clearance of it?
Is it because of the immune cell mutation?
Is it because of autoimmune response due to molecular mimicry?
Is it because of other viruses reactivating e.g. EBV which in turn can cause fatigue.
Is it a blood flow issues to brain?
Is it an infection of the brain tissue?
Is it the damage to the endothelium of the blood vessels? (Difference in sex shows that the issue is more common in women which also aligns with more immune system issues in women, hence, it is possibly the immune system vs., endothelial damage.)

A registry for long haulers

CCR5 receptor function is to help promote immune cell chemotaxis. It is also a receptor for the HIV virus.
https://en.wikipedia.org/wiki/CCR5

What is the problem (symptoms?)
More than 200 symptoms
Most common are the following
Fatigue
Body aches
Breathing issues
Brain fog/Cognitive impairment (similar to myalgic encephalomyelitis/chronic fatigue syndrome ME/CFS)
Cough
Chills
Sweat
Headache
GIT issues

Psychosomaticizing of the problem by physicians.
Outright ignoring it.
Not knowing how to approach it even when they empathize with the patient’s symptoms.

How large is the problem?
More than 30% of the COVID patients.
Not necessarily only severe cases.
UK study says about 10%

Brain fog
Fluvoxamine, glymphatic massage, neck and spine pumping.

Dr. Patterson and Dr. Yo paper
https://www.biorxiv.org/content/10.1101/2020.12.16.423122v1

Important points:
LH can result from mild infection as well. Hence, LH is not a consequence of the severe COVID only. That means labs for severe cases cannot represent accurately the LH consequence.

IL6, IL8, TNF-alpha are persistently high. They cycle.

Dr. Patterson
VEGF elevated in 79% of LH, burning sensation, neuropathy, numbness, tingling, weakness, brain fog.
Maraviroc decreases VEGF - helping with brain fog. Plus brings RANTES and IL6 down.
Triad: Ivermectin, Maraviroc, and low dose steroids are showing improvement (85%-90% are responding.)

Listen to Dr. Patterson and Dr. Yo for long hauler severity index
https://www.pscp.tv/w/1YqxoyWBjEBGv

CD8 cell count is very low - single digits. 2-7% normal is 30%. Almost as immunosuppressed as HIV.
Low CD8 count means detectable virus for 87 days
25% LHs have low CD8%.

CCR5 - allows cells to reach the area of inflammation. Maybe a delta 32 deletion causes protection against severe COVID. It is for the CCR5. It is possible that lower CCR5 receptors in heterozygous patients keeps the immune response to a lower level, while homozygous people for the CCR5 receptors have a higher number of CCR5 receptors responding more to RANTES, which in turn causes an overwhelming response to SARS-COV-2.

Note: this is not medical advice or a prescription. The following information here and in the video that goes with this is for educational purposes only.
Don’t take any medicine without your doctor’s advice. These medicines can lead to death.

General clinical signs and symptoms
Persistent headache (severe,) shortness of breath, leg pain, nose bleed, GIT pain, petechial hemorrhages under the skin, bruising under the skin, etc.
Thrombocytopenia within 5-10 days.
Platelet count dropping to 50% or more.
4T score: https://qxmd.com/calculate/calculator_113/hit-4t-s-score

Management
Management should start as soon as the diagnosis is suspected before the results from the labs are available.

Outdoor possible management.
Note, these patients must be referred to ICU/or call 911. Any wasted time can cause permanent damage.
Possible outdoor/supportive management as recommended by Prof., Greinacher et., al
Oral: Rivaroxaban, Apixaban, high dose IVIG

In Hospital and ICU
Direct thrombin inhibitors for prophylaxis and management
Argatroban IV is more important and urgent than the oral agents. Move to ICU.
Transition to warfarin or other anticoagulants (not Heparin) for 30 days when platelet count has recovered.

Labs
Normal platelet count is 150,000 to 450,000 per microliter of the blood.
Reference: healthy platelet count https://www.hopkinsmedicine.org/health/conditions-and-diseases/what-are-platelets-and-why-are-they-important
Enzyme immunoassay for heparin-induced thrombocytopenia/thrombosis are widely available
Platelet activation assays from the labs

Vitamin D - Can It Help Fight COVID-19? Watch Now (50:28)

Vitamin D

My opinion is that you keep the correct levels of vitamin D in your body. Now a days, due to staying indoors, it is possible that you will develop the deficiency of vitamin D. Get this checked by your doctor and use the correct dose to stay healthy.

Here are my notes:

Daily 10 microgram or 400 IU/Day

Lippincott’s Biochemistry Review 4th Edition. Page 388

Daily 5 mg of cholecalciferol or 200 IU of Vitamin D.

However, 800 IU/Day is shown to reduce the incidence of osteoporotic fractures.

800 IU/Day recommended by the Institute of Medicine to maintain bone health.

Frank deficiency is when the levels of 25-hydroxycholecalciferol (25OHD) is less than 20 ng/mL (50 mmol/L)

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6305614/

No consensus that the oral vitamin D supplements are helpful

Ergocalciferol from plants is called Vitamin D2

Cholecalciferol from the animal tissue is called Vitamin D3

7 deidro-cholesterol to (UV light) to cholecalciferol (D3) to 25 hydroxylase in liver to 25 OH D to -hydroxycholecalciferol 1-hydroxylase in kidney to 1,25 DiOH D3

Vitamin D Receptors are abbreviated to VDR in the notes. These are cytosolic receptors.

https://www.newscientist.com/article/2121424-vitamin-d-supplements-may-prevent-millions-of-winter-infections/

Deficiency of vitamin D makes people more susceptible to respiratory tract infections.

Vitamin D supplement can reduce these infections by 12%

Keep in mind, this is for those who are deficient in this vitamin. If you are not deficient, then it will not make a difference. Because, you are already good.

Evidence is not sufficient to say that vitamin D helps prevent respiratory infections.

2018 Study

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6305614/

People with autoimmune diseases commonly have hypovitaminosis D

What are cathelicidins?

https://www.sciencedirect.com/topics/neuroscience/cathelicidin

What are beta defensins?

https://en.m.wikipedia.org/wiki/Beta_defensin

2011 Study

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3166406/

Activation of TLR and PAMPs on macrophages increases the production of 1, alpha hydroxylase and the VDR. This in turn causes more production of cathelicidine and beta defensins 4.

Vitamin D also affects monocytes to reduce production of IL1, IL6, IL8, IL12, and TNF. Regulating the immune response.

Vitamin D acts on the dendritic cells to inhibit/reduce their differentiation and maturation. It reduces their MHCII expression, co-stimulatory molecules like CD40, CD80, CD86, decreased production of IL-12 etc.

2013 Study

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3756814/

Vitamin D improves immune system by helping produce cathelicidine and by helping modulate inflammatory cascade. Especially for the respiratory infections.

It also helps produce NFk-B (nuclear factor kappa light chain for activated B cells.)

(

Notes about the NFkB

https://en.wikipedia.org/wiki/NF-%CE%BAB

Helps with cytokine production and cell survival.

NFk-B factor becomes active when T and B cell receptors become active. Its activation causes the gene expressions that allow T cell development, maturation, and proliferation.

T and B cells have Vitamin D receptors that help them produce NFk-B

)

Continuing the notes from the study:

In pulmonary infections. Lung epithelial cells are able to convert inactive vitamin D to its active form. This active Vitamin D then helps produce cathelicidine. Which helps kill the pathogens.

Vitamin D seems to favor TH2 and TH17 cell activation which is anti-inflammatory profile.

Vitamin D seems to reduce the activation of TH1 cells which are pro inflammatory by their IFN-gamma action.

A deficiency of vitamin D may dysregulate the inflammatory response of the body.

Vitamin B also increases the IkBa. This leads to inhibition of NFkB. This helps reduce the production of IL6 and IL8 by inhibiting the production of NFkB.

Convalescent Plasma For COVID-19 Patients Watch Now (50:28)

Passive antibody therapy

Antibodies are gamma globulin proteins that make up 20% of the plasma proteins.

Immunoglobulins can be induced actively in the host (through vaccines for example), or acquired passively from other people’s plasma that have the needed antibodies.

1 person may donate plasma that will be useful for about two doses of treatment for COVID-19. It is not sufficient. So, the process is slow.

Passive immunity is used to neutralize toxins of diphtheria, tetanus, botulism. We also have passive antibodies for viruses like rabies, hepatitis A and B viruses, etc.

Plasma contains fibrinogen (for clotting) and albumin (to keep plasma in the blood vessels.) Plasma transports proteins, nutrients, antibodies, etc. to the tissues of the body. Plasma will also wash away the waste products produced by the cells.

Serum on the other hand is plasma minus the clotting factors. Serum is obtained after blood clotting. Serum contains the antibodies, hence one of its use is to test for antibodies.

Antibodies are IgG, IgM, IgA, IgD, and IgE (GAMED)

Immunoglobulins (Igs) act to neutralize the toxins. They help opsonize the pathogens. Activate complement system. And, they help prevent the attachment of the pathogens to mucosal surfaces.

Monoclonal vs. polyclonal antibodies.

Immunoglobulins are glycoproteins. They consist of a light (L) chain, and a heavy (H) chain. Simplest antibody molecule is a Y shaped complex.

Light chains’ heavy region can be either kappa or lambda. But, in one molecule of an immunoglobulin only one type of light chain will be present (either containing kappa or lambda.)

Light chains have one variable and one heavy domain.

Heavy chains have one variable and three or four heavy domains. IgG and IgA have 3, IgM and IgE have 4.

Variable regions of both the chain are for the antigen binding.

Constant region of the heavy chain is for the biological functions like binding to a cell/surface and complement activation.

GM makes classic cars. IgG and IgM activate complement.

IgG looks pregnant. It passes through the placenta.

IgA is always away to the outdoors. It sits in the surface mucosal fluids.

IgD is only a receptor on the B cells.

IgE is on the mast cells and takes parts in allergies. We don’t want too much of this unless there are worm infections.

IgG also helps opsonize (see it has a pac man like open mouth? Phagocytes have receptors for the IgG heavy chains.)

IgM can activate complement. Which in turn produces C3b which is also a opsonizing molecule. Because phagocytes also have the receptors for C3b.

IgM is usually found as five molecules joined with a J chain. Hence, it has ten binding sites (two sites on each protein.) It is the most efficient immunoglobulin and is produced as the first response.

Genes to form the heavy chains are arranged as (VVVV-D-JJJJ-HMHDHGHEHA)

Genes to form the light chains are arranged as (VVVV-D-JJJJ)

All B cells first produce IgM and IgD. Then the class switching allows them to produce IgG, IgE, and IgE. Various cytokines can influence the switching to various Immunoglobulin types.

Once a specific heavy chain has been spliced out, that immunoglobulin cannot be made any more by this B cell.

Every new encounter with the antigen improves the response. This is because of somatic hypermutation and affinity maturation.

28% had lung cancers. The highest cancer type with COVID-19.
25% of the cancer and COVID-19 had received chemotherapy or surgery within the last one month.
Patients with lung cancer did not have a higher probability of severe events compared to other cancers (see below for the definition of the severe event.)
25% were cancer survivors.
Cancer patients deteriorated more rapidly than non-cancer COVID-19 patients.

Compared to patients without cancers

Cancer patients were older mean age 63.1 y, vs. 48.7 y.
More likely to have a h/o smoking 22% vs 7%
Had more severe baseline CT manifestations. 94% vs 71%
No difference in sex, other baseline symptoms, or other comorbidities.

Excerpt
Hence, in viral infections, NK cells are thought to play a central role primarily in the early stages of the response, in which they function to restrain viral replication until the adaptive immune response is sufficiently developed to control the infection.
Studies of mice with a mutation in the perforin gene demonstrated that perforin-dependent cytotoxicity plays an important role in controlling MCMV replication in the spleen but little or no role in the liver (172,173).

Important: NK cells are useful in the early stage of the infection by reducing the replication and giving a chance to the adaptive arm to become ready.

Functional exhaustion of antiviral lymphocytes in COVID-19 patients
https://www.nature.com/articles/s41423-020-0402-2?proof=trueIn%25EF%25BB%25BF

We showed that the total number of NK and CD8+ T cells was decreased markedly in patients with SARS-CoV-2 infection. The function of NK and CD8+ T cells was exhausted with the increased expression of NKG2A in COVID-19 patients. Importantly, in patients convalescing after therapy, the number of NK and CD8+ T cells was restored with reduced expression of NKG2A. These results suggest that the functional exhaustion of cytotoxic lymphocytes is associated with SRAS-CoV-2 infection. Hence, SARS-CoV-2 infection may break down antiviral immunity at an early stage.

More prone to dehydration due to elevated glucose. (As the kidneys throw the glucose out and in the process throw the water out as well.) So keep it controlled.
When A1C goes in 9-10 range then the risk of complications increases significantly.

What to do?
Wash hands
Wear mask
Get a flu shot
If you are insulin dependent then keep extra insulin at hand.
Keep your diabetes and hypertension well managed.

What happens to immune system in diabetes?
https://www.ncbi.nlm.nih.gov/pubmed/19069085

https://www.researchgate.net/post/What_is_cause_of_immunosupression_in_diabetes_melitus

Chronic hyperglycemia causes blood vessel narrowing and damage leading to slower perfusion and nerve damage. Nerve damage occurs both because of poor blood supply to the nerves and the accumulation of glucose in the myeline sheath and damaging it.

High glucose levels impair neutrophil activity (innate arm.)
Cytosolic calcium increases in PMN cells. This in turn reduces their ability to phagocytose. It happens because high levels of calcium reduce the synthesis of ATP that in turn is needed for the cellular function.
Study showing that the hyperglycemia increases intracellular calcium: https://www.ncbi.nlm.nih.gov/pubmed/9387128

PMN chemotaxis is also impaired.
Reduced complement response
Reduced leukocyte adherence to the blood vessels. Study mentioning endothelial dysfunction: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3348526/
Reduced response to pathogens
Chronic hyperglycemia leads to acidosis which further reduces the activity of the immune system. (Study mentioning immune dysregulation with various acids: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1065014/)
Skin cells become less efficient and skin and urinary infections become common.

Additionally, the reduced carbohydrate metabolism causes increased fatty acids mobilization. This results in the vascular endothelium to become atherosclerotic. Resulting also, in the narrowing of the blood vessels and reduced perfusion.
High free fatty acids also cause high levels of reactive oxygen species. This in turn makes our tissues prone to easy damage.
FFA cause disruption of insulin responding mechanisms.
Inflammation caused by ROS leading to adipocyte insulin resistance and inflammation: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4995181/

Hyperglycemia causes an increase of dicarbonyl production. Dicarbonyl in turn reduces the function of beta-definsins. That are necessary to kill pathogens.

Over eight months, the researchers will conduct rounds of diagnostic tests using nasal swabs to identify infections. And they will take saliva and blood samples to look for antibodies, which would indicate that such people had had COVID-19 and recovered — perhaps without ever realizing they’d been infected with the coronavirus.

25% of the infected may be asymptomatic

CDC Director On Models For The Months To Come: 'This Virus Is Going To Be With Us'
https://www.npr.org/sections/health-shots/2020/03/31/824155179/cdc-director-on-models-for-the-months-to-come-this-virus-is-going-to-be-with-us

I have been saying this for a long time.

1 in 4 people can be asymptomatic

One of the [pieces of] information that we have pretty much confirmed now is that a significant number of individuals that are infected actually remain asymptomatic. That may be as many as 25%. That's important, because now you have individuals that may not have any symptoms that can contribute to transmission, and we have learned that in fact, they do contribute to transmission.
And finally, of those of us that get symptomatic, it appears that we're shedding the significant virus in our oropharyngeal compartment, probably up to 48 hours before we show symptoms. This helps explain how rapidly this virus continues to spread across the country because we have asymptomatic transmitters and we have individuals who are transmitting 48 hours before they become symptomatic.

Is Reinfection From SARS-COV-2 Possible? Watch Now (38:30)

SARS-COV-2 Reinfection

We need to know the following to follow this talk
What is reinfection?
What is reactivation?
What is a carrier?
What is a false negative?
What is a false positive?
What is the sensitivity of a test?
What are immunoglobulins?
What is the role of IgM, IgG, and IgA?
What is seroconversion?
What is class-switching?
How long do the memory B cells live?

Notes
Immunoglobulins are formed from the day 7-10. First IgM and then IgG. (In case of SARS-COV-2 N protein, IgG is formed from the day 4th.)
IgA will be formed and sent to live in the mucus membranes.
Immunoglobulins peak near 3 months.
Formed antibodies live from a few weeks to months in the body.
Memory cells are formed in the process that will respond within 24-48 hours when the pathogens arrive in our body again.
New IgG and IgA are formed to combat the virus.
in the case of SARS-COV-1, the antibodies were produced up to 3 years after the recovery.
In rhesus monkeys, the SARS-COV-2 reinfection was not successful.

What can fail our immune system?
1. Weak immune system.
2. Immunosuppression
3. False-negative tests
4. False-positive tests
5. Viral mutation

Immune System Response to SARS-COV-2 is humoral in nature
https://onlinelibrary.wiley.com/doi/10.1002/rmv.2107
IgG against N proteins starts on the day 4
Most patients seroconverting by day 14
Peak specific IgM after 9 days of the infection.
Class switching to IgG in the second week.

Mobeen’s thoughts:
Enough time is not passed to know how long the antibodies will live?
Enough time is not passed to detect how long the memory cells can continue to produce antibodies to the virus?
I will take the standard immune response and say that we will be immune for at least 3 months to 3 years. 3 months considering the existing antibodies. 3 years considering the memory cells.
Reinfection is not possible during the immune phase.
Reactivation is not proved.
Possibly false negative at the time of discharge. Or false positive at the re-test. Or a more sensitive test that can pick up the remnant RNA pieces from the mucus membranes and the cells.
GIT can keep the virus for 50 days after the recovery but is not significant.
Do we have carriers? Folks, that are asymptomatic but allow the virus to shed?

SARS-COV-1 (from 2012-2015) shows that the coronavirus antibodies can be produced for up to 3 years after the recovery.
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2851497/

Reinfection could not occur in SARS-COV-2 infected rhesus macaques
https://www.biorxiv.org/content/10.1101/2020.03.13.990226v1.full
Excerpt from the study
Importantly, the unsuccessful rechallenge in NHP models suggested that the re-positivity from discharged patients could not be due to reinfection.

Re-detectable positive RNA test in recovered patients.
https://www.medrxiv.org/content/10.1101/2020.03.26.20044222v1.full.pdf

Maybe the new test was hypersensitive in these RP patients (RP = re-detectable positive)?

The study found that the patients remained asymptomatic, their disease did not progress, and they did not cause infections to others.

Excerpt from the discussion
And from a recent longitudinal study in SARS-CoV-2 infected rhesus macaques, reinfection could not occur in convalescent monkeys [20]. Long-term follow-up of these close contacts with RP patients will warrant the evaluation of the possible risk of RP

It may have been a less sensitive test.
Excerpt from the study
Our data support the notion that the false negatives using commercial kit may partially account for the RP because the kits had only 30%–50% positive rate of detection

Maybe the immune response via IgA was not sufficient to clear the virus from the mucus membranes?
Excerpt from the study
Nor could we exclude immunological factors including low mucosal immune responses such as low IgA levels.

Study where patients were positive after 5-13 days of discharge. They did not have disease progression and they did not make their family members sick.
https://jamanetwork.com/journals/jama/fullarticle/2762452
The study thinks that these folks may be carriers.

Let’s understand the antibodies. Immune cell behavior, and memory cells. Let’s also look at the passive immunity i.e. antibodies given from outside.

Antibodies are produced for about 7-10 days. IgM first and then IgG.

Memory B cells respond within 24-48 hours. (Reference: https://academic.oup.com/occmed/article/57/8/552/1474357)

Passive immunity lasts from a few weeks to months.

Will Coronavirus Pandemic Diminish by Summer?
March 17, 2020
https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3556998

83% of testing has been in non-tropical countries (30N and above).
90% of the cases are recorded in the range of 3C to 17C.
72% of the cases are in the areas with humidity between 3 to 9 g/m3.

Most tropical countries have not tested as extensively as northern countries. (Mobeen’s comment: what about China and South Korea? South Korea did a lot of testing. South Korea is 35.90N)

Several countries between 30N and 30S such as Australia, UAE, Qatar, Singapore, Bahrain, Qatar, and Taiwan have performed extensive testing per capita and the number of positive 2019-nCoV cases per capita is lower in these countries compared to several European countries and the US.

Current data, although limited, suggests that it is extremely unlikely that the spread of 2019-nCoV would slow down in the USA or Europe, due to environmental factors, because a large number of cases have already been reported in the range of AH and T experienced by these regions for the most part of the year.

if, new cases in April and May continue to cluster within the current observed range of AH i.e. 3 to 9g/m3, then the countries experiencing monsoon, i.e. having high absolute humidity (more than 10 g/m3) could see a slowdown in transmissions, due to climatic factors.

Our results in no way suggest that 2019-nCoV would not spread in warm humid regions and effective public health interventions should be implemented across the world to slow down the transmission of 2019-nCoV.

Excerpt
"Wherever the temperatures were colder, the number of the cases started increasing quickly," said Qasim Bukhari, a computational scientist at MIT and a co-author of the study. "You see this in Europe, even though the health care there is among the world's best," Bukhari said.

https://www.cdc.gov/mmwr/volumes/69/wr/mm6913e1.htm

Conclusion

This analysis suggests that symptom screening could initially fail to identify approximately one half of SNF residents with SARS-CoV-2 infection. Unrecognized asymptomatic and presymptomatic infections might contribute to transmission in these settings. During the current COVID-19 pandemic, SNFs and all long-term care facilities should take proactive steps to prevent introduction of SARS-CoV-2, including restricting visitors except in compassionate care situations, restricting nonessential personnel from entering the building, asking staff members to monitor themselves for fever and other symptoms, screening all staff members at the beginning of their shift for fever and other symptoms, and supporting staff member sick leave, including for those with mild symptoms (3). Once a facility has a case of COVID-19, broad strategies should be implemented to prevent transmission, including restriction of resident-to-resident interactions, universal use of facemasks for all health care personnel while in the facility, and if possible, use of CDC-recommended PPE for the care of all residents (i.e., gown, gloves, eye protection, N95 respirator, or, if not available, a face mask) (3). In settings where PPE supplies are limited, strategies for extended PPE use and limited reuse should be employed (4). As testing availability improves, consideration might be given to test-based strategies for identifying residents with SARS-CoV-2 infection for the purpose of cohorting, either in designated units within a facility or in a separate facility designated for residents with COVID-19. During the COVID-19 pandemic, collaborative efforts are crucial to protecting the most vulnerable populations.

Soluble Spike Proteins by Adenovirus Vaccines?

A pre-print study has caused a lot of sensation for two reasons. One, that it proves how Adenovirus based vaccines especially AstraZeneca causes clotting. And, second that it shows how the spike proteins are found in the blood. Let’s review this study.

Pre-print
https://www.researchsquare.com/article/rs-558954/v1

PDF of the hypothesis/pre-print
https://assets.researchsquare.com/files/rs-558954/v1/8c30a186-e9e2-47c1-a76c-dc3bdf10c22a.pdf

What has to happen to prove this hypothesis?
1. Incorrect gene splicing has to occur. If not then the rest is not going to work.
2. Spike protein has to be built, but not have the anchoring part.
3. Spike protein has to be soluble, or part of it has to become soluble.
4. It has to be secreted but not able to attach on the surface of the cell.
5. Vaccine has to fail in producing neutralizing antibodies. (Mobeen, spike protein antibodies of any sort that can bind with this free and soluble spike protein.)
6. It has to enter the blood stream safely. Without getting phagocytosed. And, move through the capillary gap junctions.
7. It has to end up in the blood stream, and then combine with ACE2 as well. However, it has to not combine with the ACE2 in the local tissue where these were actually released.
8. Now this combination should be attacked by the antibodies resulting in the local inflammation. But, did we not say that these proteins got out and floated about because there was no antibody to bind to them? So, why there are antibodies binding now when the protein is in the blood?
9. Now, also, the NK cells will attack this complex causing local inflammation. They also need antibodies to be bound to this soluble protein.
10. Complement will also become activated by the Fc receptors. Attracting C3b or activating the complement cascade.

Relative Risk = Risk in vaccinated/risk in placebo = 0.06/3.9 = 0.015
Efficacy: 1 - Relative Risk = 1 - 0.015 = 0.985 = 98%

Cases in the cohort that received 1 dose: 3,953
Deaths: 18 (0.45%)

Unvaccinated: 976
Deaths: 38 (3.9%)

Consider that received second dose can still be a risky time.
Absolute risk reduction: 3.9-0.45 = 3.45%
Relative Risk = Risk in vaccinated/risk in placebo = 0.45/3.9 = 0.12
Efficacy: 1 - Relative Risk = 1 - 0.12 = 0.88 = 88%
