The new variant of significance coming from Botswana/ S. Africa (B.1.1.529/”Nu”)– not the unvaccinated in the states as I noted many times here. We are likely over vaccinating here when the variants are coming from countries with limited vaccination and sanitization. Many think we can just stop it by vaccinating here in the states – its not going to happen unless we want to isolate from the world. Last report we noted the diminishing returns of vaccinating beyond 60%. – https://covid19mathblog.com/2021/11/covid-11-24-21/

“Researchers spotted B.1.1.529 in genome-sequencing data from Botswana. The variant stood out because it contains more than 30 changes to the spike protein — the SARS-CoV-2 protein that recognizes host cells and is the main target of the body’s immune responses. Many of the changes have been found in variants such as Delta and Alpha and are linked to heightened infectivity and the ability to evade infection-blocking antibodies.
But the variant’s apparent sharp rise in South Africa’s Gauteng province — home to Johannesburg — is also setting off alarm bells. Cases increased rapidly in the province in November, particularly in schools and among young people, according to Lessells. Genome sequencing and other genetic analysis from de Oliveira’s team found that the B.1.1.529 variant was responsible for all of 77 of the virus samples they analysed from Gauteng, collected between 12 and 20 November. Analysis of hundreds more samples are in the works.
The variant harbours a spike mutation that allows it to be detected by genotyping tests that deliver results much more rapidly than genome sequencing,”
“The variant harbours a high number of mutations in regions of the spike protein that antibodies recognize, potentially dampening their potency. “Many mutations we know are problematic, but many more look like they are likely contributing to further evasion,” says Moore. There are even hints from computer modelling that B.1.1.529 could dodge immunity conferred by another component of the immune system called T cells,”
Good news S. Africa is not seeing a super surge relative to last year. But note vaccination rate per capita still under 25%
Looks like NU is in Belgium – https://www.newsweek.com/nu-b-1-1-529-covid-variant-botswana-south-africa-belgium-europe-1653545
Belgium is surging even with a 75% vaccination rate! About to breach last years peak.
So much effort put in vaccine – perhaps we could have overlooked the obvious? Common allergy medicine to treat covid-19 e.g. Benadryl? https://www.mdpi.com/2076-0817/10/11/1514/htm
“Conclusions: Sigma receptor ligands and drugs with off-target sigma receptor binding characteristics were effective at inhibiting SARS-CoV-2 infection in primate and human cells, representing a potential therapeutic avenue for COVID-19 prevention and treatment.”
“Common antihistamines that exhibit off-target antiviral activity include hydroxyzine, azelastine and diphenhydramine”
“It is clear that multiple sigma receptor ligands exhibit antiviral properties against SARS-CoV-2, but the relative roles of the sigma-1 receptor and sigma-2 receptor agonism and antagonism in modulating antiviral activities are not known.”
“We investigated the ability of diphenhydramine to inhibit SARS-CoV-2 induced cytotoxicity and found an EC50 of 122.0 μg/mL (418 μM; Figure 8A,B), about 7 times higher than that found in the plaque reduction assay, similar to our findings with AZ66. We hypothesized that diphenhydramine could be combined with structurally distinct antiviral agents (binding other receptors, not sigma) to reduce its EC50 for antiviral activity against SARS-CoV-2.”
“The combination of diphenhydramine+lactoferrin showed a combined ability to reduce SARS-CoV-2 repication by half that observed for diphenhdydramine alone. The data from the more physiologically relevant human lung cell lines demonstrate the potential for sigma receptor ligands and drugs with off-target effects on sigma receptors to inhibit SARS-CoV-2 replication.”
“Data suggests that specific drugs that bind SARS-CoV-2, or interacting host proteins, also have the potential to prevent COVID-19. For example, hydroxyzine is a first-generation antihistamine that exhibited off-target binding to the SARS-CoV-2 host receptor ACE2 [37] and the sigma-1 receptor. Usage of hydroxyzine (and structurally related antihistamines diphenhydramine and azelastine) was associated with reduced incidence of SARS-CoV-2 positivity in a population of more than 219,000 individuals in California [8]. Hydroxyzine, diphenhydramine and azelastine exhibited direct antiviral activity against SARS-CoV-2 infection of Vero E6 cells in vitro. Since antihistamines act as nasal decongestants and cough suppressants, the on- and off-target binding properties of drugs such as diphenhydramine may have broad utility in prevention and treatment of COVID-19.”
“We found that co-administration of 400 μg/mL of lactoferrin with diphenhydramine reduced SARS-CoV-2 induced cytotoxicity and decreased the EC50 (Figure 8C,D). The antiviral enhancement effects of lactoferrin were more apparent at lower, therapeutically relevant concentrations of diphenhydramine (Figure 8E). Combining lactoferrin with diphenhydramine resulted in synergistic effects on antiviral activity against SARS-CoV-2 (Figure 8F). Compounds we found effective in Vero E6 were validated in their ability to reduce infectious SARS-CoV-2 production following infection of human lung epithelial cells”
Diphenhydramine – this is just Benadryl – also relatively cheap.
Charging various levels of insurance will open a pandora’s box – hopefully move beyond just the vaccination status as it looks to be legal to have a spread on insurance per health – https://www.npr.org/2021/11/22/1056238770/covid-delta-unvaccinated-higher-health-insurance-premiums
“As Covid cases surged over the summer, Delta Air Lines CEO Ed Bastian took action: Unvaccinated workers would have to pay an extra $200 a month for their health insurance, starting Nov. 1.”
“Now, as Covid cases climb once again, more companies are putting aside carrots and turning to sticks in an effort to protect their workers. From Utah grocery chain Harmons to Wall Street banking giant JPMorgan Chase, companies are telling their unvaccinated workers to get the shots or pay more for health insurance.
In a September survey, the Society for Human Resource Management found less than 1% of organizations had raised health insurance premiums for unvaccinated workers and 13% have considered doing so. It was higher among large companies, where nearly 20% were considering the move. ”
“According to federal law, companies are allowed to charge employees different amounts for health care as long as they do it through a program designed to promote healthy behaviors and prevent disease.
For example, a company may run a wellness program that encourages employees to accumulate a certain number of steps every day or sets targets for BMI, a measurement of body fat based on height and weight. There are also wellness programs aimed at preventing and curbing tobacco use.”
“As part of these programs, companies can offer rewards or penalties for meeting certain targets, such as getting vaccinated. But they must not exceed 30% of the cost of the employee’s health care plan, calculated as the amount paid by the employee and the employer combined. The maximum penalty rises to 50% for wellness programs targeting tobacco use.”
“To ensure that wellness programs do not violate discrimination laws, companies must provide waivers for individuals who have medical reasons for not meeting the stated targets or alternative ways for them to satisfy the requirements.”
I will state unequivocally that a healthy young unvaccinated adult would be superior to an older obese person that is vaccinated in terms of reducing transmission of covid and long term health care cost.
To state the vaccine is 100% safe is not true – therefore it should be a doctor patient consult to conclude the risk/reward for vaccination. – https://www.ahajournals.org/doi/abs/10.1161/circ.144.suppl_1.10712?s=09
“Our group has been using the PLUS Cardiac Test (GD Biosciences, Inc, Irvine, CA) a clinically validated measurement of multiple protein biomarkers which generates a score predicting the 5 yr risk (percentage chance) of a new Acute Coronary Syndrome (ACS)”
“The score has been measured every 3-6 months in our patient population for 8 years. Recently, with the advent of the mRNA COVID 19 vaccines (vac) by Moderna and Pfizer, dramatic changes in the PULS score became apparent in most patients.This report summarizes those results. A total of 566 pts, aged 28 to 97, M:F ratio 1:1 seen in a preventive cardiology practice had a new PULS test drawn from 2 to 10 weeks following the 2nd COVID shot and was compared to the previous PULS score drawn 3 to 5 months previously pre- shot. Baseline IL-16 increased from 35=/-20 above the norm to 82 =/- 75 above the norm post-vac; sFas increased from 22+/- 15 above the norm to 46=/-24 above the norm post-vac; HGF increased from 42+/-12 above the norm to 86+/-31 above the norm post-vac. These changes resulted in an increase of the PULS score from 11% 5 yr ACS risk to 25% 5 yr ACS risk. At the time of this report, these changes persist for at least 2.5 months post second dose of vac.We conclude that the mRNA vacs dramatically increase inflammation on the endothelium and T cell infiltration of cardiac muscle and may account for the observations of increased thrombosis, cardiomyopathy, and other vascular events following vaccination.”
Vaccines impact beyond cardio observed and one needs/should consult with your doctor to make the best decision for you – NOT just generically take the vaccine without a true consult – https://academic.oup.com/rheumatology/article/60/SI/SI90/6225015?s=09
“The safety profile of mRNA-based vaccines in patients with autoimmune inflammatory rheumatic diseases (AIIRD) is unknown.”
“Epidemiologic studies on the safety of the mRNA-based COVID-19 vaccines in patients with AIIRD are needed to clarify the association between the BNT162b2 mRNA vaccination and reactivation of zoster.”
Europe is surging.
Europe includes Russia Below.
Germany is surging
NY is surging now —-its cold now.
NY is over 60% vaccinated. Showing major improvement in fatality rate but this comparing with many deaths from poor nursing home strategies.
The spread is coming to the cold parts of the country without much help from being vaccinated.
