NEWS BRIEF OF THE DAY  (11/14/2020):

SARS-CoV-2 mRNA vaccine technologies 

 LINK

There are four main safety and efficacy advantages of the use of mRNA-based antiviral vaccines over traditional approaches. First, mRNA-based antiviral vaccines minimize the potential risk of infection and insertion-induced mutagenesis due to natural degradation of mRNA in the cellular microenvironment. Second, the immunogen’s high efficacy due to engineered mRNA structural modifications improves its stability and translation efficacy. Third, the high potency of mRNA-based vaccines capable of generating potent antiviral neutralizing immunoglobulins with only one or two low-dose immunizations may induce strong immune responses by activating both CD8+ and CD4+ T cells. Fourth, engineered mRNA production facilitates large-scale production of sufficient vaccine doses required to treat mass populations. All these factors make the mRNA vaccine more suitable for a rapid response to the emerging COVID-19 pandemic.

NEW TOPIC of CONTROVERSY:


"Herd Immunity" by rampant infection? -  Is it a possibility?   NO. 

Why?  No infectious agent has ever done so on its own.  The premise is a thought experiment where people of low risk get infected and resolve the infection without harm and that it would have to be about 65% of the US population placed at risk of infection sequelae (aka the "long haulers").


Herd immunity might be possible for COVID-19 by immunization. However, the antibody response wanes in a few months and advocates suggest T-cell memory will reinstate B-cell antibodies upon a reinfection.  The problem is clonal replenishment of Abs takes weeks,  coupled with the known damping of INF by COVID-19, provides for sustained viral injury and future health staus is likely compromised.with each new re-infection. 


If we allow rampant infection with a 2.75% death rate (current Oct) then 210M (65% of 328M population) will yield 5.7M deaths.

 NEWS!!!   Jan 1, 2021:  The US has hit 20M infections and 350,000 deaths.  The CDC expects another 70,000 deaths by Jan 20th. The rate of vaccinations is 13% of what was expected (2.7M vaccinations vs 20M anticipated).  What have we learned about COVID-19 in 2020?  Here is a short summary (click the link):  15 Lessons on COVID-19

We have our December Update (No 7 in the series) ready and it is available - HERE 
Plus New Supplement No. 1 on:
  Vitamin D and COVID-19
and a New Supplement No. 2 (Jan 11th update) on: 
The UK and South African COVID-19 Variants and Risk 
The South African and UK variants are showing greater "infectivity" with Ct values (PCR cycle numbers) less than the preexisting variants

and a new supplement on Radiation Injury and COVID-19 Injury

The Ct score is the PCR "cycle number" (number of amplification cycles) to obtain a statistically "real" signal (viral copy number). The South African variant has a lower (more infectious) Ct score versus three other previous variants. 

Our COVID-19 Bimonthly Update Presentations.  We have delved deep into the science behind this pandemic and the public needs help in understanding the terminology, the tests, the risks and how to navigate these troubled times.  We hope these slide decks will help you.
