Mining the Lancet Letter on relevance of the vaccinated & CDC Study of Delta Variant Infections

 +
JMJ

 The "vaccines" prevent neither infection nor transmission.  A recent article in The Lancet showed no statistical difference in secondary attack rates in households based on vaccine status.  A CDC study of an outbreak in a Texas prison showed 24% effectiveness in preventing disease across the entire study period and 3% for time more than 4 months beyond "full vaccination".( Suscipe Domine: Strickland: ‘I’d rather die than benefit from anything produced by using aborted ... )

The words above were written by Rock on the Suscipe Domine forum (link to post), and being of a critical mind (which sometimes gets me into trouble), I wondered what the source materials stated and if this aligned with Rocks perspective.

 Reading the above quote there are three assertions:

  1. Vaccines prevent neither infection nor transmission.
  2. There is no statistical difference in secondary attack rates based on vaccine status. 
  3. Vaccine efficacy in Texas prison was 24% across study period and 3% at four months+

 Rock kindly provided links to the documents and here's my thoughts after reading the reports.

First, the Lancet Letter. These are letters sent to the editor and are not peer reviewed. 

The letter itself discusses infection of other household members by breakthrough cases and the German reference is in the 60+ age cohort. The rates are the same between breakthrough and unvaccinated. 

Meaning that if you get infected by a breakthrough case the viral load is the same for unvaccainted.  

This doesn't mean that the vaccinated with no 'breakthrough' cases transmit SARS-CoV-2.

Neither of these results are surprising given what we know about immune system performance in that cohort. The whole point of the letter is that public health agencies need to take into consideration that the vaccinated need to be considered as a "relevant source of transmission".

Lancet Letters: The epidemiological relevance of the COVID-19-vaccinated population is increasing

The thirst claim is that vaccine efficacy was as low as 24% and 3% at four months.  Yup.  The scenerio with a bunch of inmates in close quarters would create high viral loads - so I'm not surprised that they had issues. 

 Interestingly, given the 'experiment' conditions:

The attack rate was higher among unvaccinated versus fully vaccinated persons (39 of 42, 93% versus 129 of 185, 70%; p = 0.002).

So in a closed environment where dozens of people are close proximity, there will be more transmission and higher viral loads.

This reminds me, I wonder if they have figured out the viral load needed for symptomatic disease.  

CDC: Outbreak of SARS-CoV-2 B.1.617.2 (Delta) Variant Infections Among Incarcerated Persons in a Federal Prison — Texas, July–August 2021

Caveat: I am tired, so I may have misread the study papers.

Tradical Thoughts


What is the goal of the vaccination campaign? 

Ultimately to remove 'novel' from the phase Novel Coronavirus.


The problem with SARS-CoV-2 is that it is 'novel'.  Meaning it is (was) sufficiently different from the previous viruses that by the time a large number of our immune systems would mount a response it would be too little, too late.

The vaccinations are an attempt to aid in removing the novelty from the equation. 

The data that I've heard about (caveat not fact checked deeply) is that even the break through infections are milder that those without infection.

So combining infection survivors and vaccinated people - eventually the pandemic will burn itself out.

That is lifecycle of pandemics - it comes - it kills - people survive - and immunity is good for a while ... until the next virus. 
 
In my work, I have reviewing various biological threats and my conclusion is that SARS-CoV-2 is a wake-up call.  The measures put in place after SARS-CoV-1 were dropped shortly afterwards and complacency became the norm.  The stage was set for this outbreak to turn into a pandemic.

If this has been any of the more lethal viruses, then the morgues would be over capacity as well as the hospitals.

So what to do?  

Well, I think in the grand scheme of things it is a case of: 


Keep up your Spritual Life, study the Faith, receive the Sacraments. This way you'll know what "hill to die" ... hopefully only metaphorically.

Rome,the SSPX and this time of Crisis - Updated

+ JMJ Obviously there's lots of events right now. First we have the April 1st - I almost thought it was April Fools - meeting between Pope Francis and Bishop Fellay.  Nothing really news worthy as this is a natural progression as Rome appears to be considering fulfilling Archbishop Lefebvre's wish to 'accept us as we are'. Second we have the April 8th publication of what will be a verbose exhortation of the Synod of the Family. I'm willing to bet that the Pope will give with one hand (unilateral regularization of SSPX) and take with the other (ambiguous document that opens the flood gates of sin further). Much to pray for.

The Vatican and SSPX – An Organizational Culture Perspective

Introduction The recent and continuing interactions between the Vatican and the SSPX have been a great opportunity for prayer and reflection.  The basis for the disagreement is theological and not liturgical. As noted by Dr. Lamont (2012), the SSPX theological position on the four key controversial aspects of the Second Vatican Council are base on prior theological work that resulted from relevant magisterial pronouncements.  So it is difficult to understand the apparent rejection of the theological position of the SSPX.

A Reply to Martin Blackshaw’s FLAWED Remnant article titled: FLAWED: SSPX Advice on Abortion-tainted Vaccines

 + JMJ    An article has appeared in the Remnant (link to article) and I am afraid that there are a number of flaws in it that need to be addressed. The author, Martin Blackshaw, believes that both the Church and the SSPX are misapplying the principle of Moral Theology called 'Cooperation In Evil'.  Unfortunately, Mr. Blackshaw rests most of his arguments on citing authors that support his position, without considering the possibility that they are wrong. This highlights a key factor in this crisis: ignorance of the faith and its application . I don't am not singling out Mr. Blackshaw for this criticism, I have observed that it applies to laity and religious, superior and subject a like.  No one seems immune in this enduring crisis, myself included.  I further believe that this ignorance is why so many Catholics, both traditional and non, rely on their gut feeling or "Catholic conscience" for charting their way through this crisis of the faith.  While...

Battle Joy

+ JMJ I was listening to a Cd of John Vennari on Battle Joy ( Recapture the Flag: Dedication and Battle Joy - by John Vennari ) and it really captures a key point that Catholics (Traditional and otherwise labelled) need to adopt. We should see this conflict as a chance to prove our mettle for our King and to earn our unending reward.  As veterans we'll be able to talk about the old battles in which we fought and the honour we gained in fighting for our King! Attached is a preview of course that, although secular, contains some of the elements of Battle Joy. P^3 https://www.coursera.org/learn/war/lecture/VDwfk/the-joy-of-battle

SSPX and the Resistance - A Comparison Of Ecclesiology

Shining the light of Church Teaching on the doctrinal positions of the SSPX and the Resistance. Principles are guides used to aid in decision making.  It stands to reason that bad principles will lead to bad decisions. The recent interactions between Rome and the SSPX has challenged a number of closely held cultural assumptions of people in both sides of the disagreement. This has resulted in cultural skirmishes in both Rome and the SSPX. Since it is the smaller of the two, the skirmishes have been more evident within the SSPX.  The cultural fault-line that Bishop Fellay crossed appears to be linked to two points of Catholic Doctrine: Ecclesiology and Obedience.  The cultural difference of view points is strong enough that it has resulted in the expulsion of a number of members.  It should also be noted that some other priests expelled since the beginning of the latest interactions (starting in 2000) held the same view points and have joined with the l...
