A Question for Mandated-Vaccination Advocates

 

How are you quantifying the public health risk represented by any given individual not getting vaccinated? Can you give it to me in units of, say, third-party life years lost per year by the decision to remain unvaccinated? Can you give me an estimated probability that the failure of individual X to get vaccinated will result in the COVID death of some individual Y?

No? Can you at least try?

Because you’re giving us a value-of-freedom vs. cost-of-risk inequality that looks something like this:

Freedom < Risk

And I want to know when you think the cost of the risk no longer outweighs our personal freedom to make health care choices for ourselves.

If you can’t give me a number, can you give me a ratio? Can you tell us what relative reduction in risk will drop it below the value you seem to place in individual choice?

Don’t tell me you don’t know. We don’t want to trade our freedom for don’t know.

And it isn’t obvious to me that you’ve got the direction of that inequality right even now. If neither of us knows what the actual risk is, I at least know how much I value individual freedom. So the ball’s in your court and, until you come back with some science and a better argument than I’ve heard, I’m going to assume the freedom I value outweighs the risk you can’t or won’t quantify.

And, until you put a number on it, don’t call it science.

    Jerry Giordano (Arizona Patrio&hellip; (View Comment):
    The expected number of deaths from my decision not to be vaccinated is 0.88. This can be split into an expected number of 0.77 deaths of unvaccinated persons and 0.11 deaths of vaccinated persons. Another way of looking at is that if I decide not to be vaccinated — hypothetically, as I actually am vaccinated — then there is a 77% chance that some unvaccinated person will die, and a 12% chance that some vaccinated person will die.

    If an unvaccinated person results in .88 deaths, shouldn’t there be like 150-200 MILLION people dead in the US, especially since there was no vaccination for quite a while?

    Good question.

    First of all, this is a calculation using the Delta transmissibility figure, which is more recent.

    More importantly, though, as I pointed out in my comment # 78, the calculation involves a chain of transmission from the initial infected unvaccinated individual through many others — 73 in this particular calculation, which considers the death risk resulting from the first 4 transmission steps.

    I might not have been clear about how this works. Based on my assumptions, each infected unvaccinated person will infect 2.6 other unvaccinated persons. The 2.6 figure is from the assumed transmissibility of the Delta variant (6.5) times the assumed percentage of the population unvaccinated (40%).

    So if I were infected and unvaccinated, I would infect (statistically) 2.6 other unvaccinated people. That’s the first step. They would each infect another 2.6 — a total of 6.76 at the second step. They would each infect another 2.6 — 17.576 at the third step. And they would each infect another 2.6 — 45.6976 at the fourth step.

    If you add these up, plus me, you get 73.6336 unvaccinated people who become infected in the first four steps. For each such person X, the increased risk of death to a person in the next step, compared to the risk if person X was vaccinated, is 0.01196. Multiply 73.6336 by 0.01196 and you get 0.8806579, which I rounded to .88 in reporting the expected number of deaths from my (hypothetical) decision not to be vaccinated.

    What happens when the unvaccinated carrier can’t find other unvaccinated victims?

    So much of this sounds like the Star Trek savants. They were “sure,” too.

    Right.  So was Churchill.

    This is a pretty weak response to an argument that you can’t rebut.

    If you are unvaccinated: When you get Covid, you will infect 6.5 others, 3.9 vaccinated and 2.6 unvaccinated. The expected number of deaths is 0.0005 among the vaccinated and 0.013 among the unvaccinated. The total number of expected deaths, from the direct infections that you would cause if unvaccinated, is 0.01495.

    If you are vaccinated, you will infect 1.3 others, 0.78 vaccinated and 0.52 unvaccinated. The expected number of deaths is 0.0005 among the vaccinated and 0.0026 among the unvaccinated, a total number of deaths from direct infections that you would cause if you were vaccinated of 0.00299.

    The reduction in this first-order expected number of deaths, from your vaccination, is 0.01196.

    My emphasis in your quote. I can’t validate your numbers, but we are in agreement as to decreased transmission for those vaccinated.

    Yet, the vaccinated are more likely to become infected than their proportion of the population – meaning that the vaccine increases their chance of catching COVID.

     

    I have not seen that. Recent article of hospitalizations in NY (I can’t remember if state or city) said that we were averaging 330-something of non vaccinated per week against 70-something per week vaccinated.

    But the vaccinated get less severe Covid so don’t require hospitalization at the same rate as unvaccinated.

    Right. That alone should tell you to get vaccinated. To answer your other reply, there may not be a difference in getting the virus between vaccinated and not. My argument is that vaccinated people have less time to transmit the virus if they get it.

    Depends on what you mean by asymptomatic. If you’re asymptomatic and not carrying the virus, then you can’t transmit it because you don’t have it. If you’re asymptomatic and are virally infected (which is possible) then of course you can transmit it like anyone who is is infected but symptomatic. One caveat, I don’t know if the transmission rate is the same.

    There is no way that bein asymptomatic is the same as someone who has symptoms. No way. that would be unlike any other virus in history.

     

    That’s probably true.

    Did you see my comment earlier:

    Doctor Peter McCullough says that when we had a new vaccine developed for swine flu in the 1970’s, when there were 53 unexplained deaths attributed to the vaccine, vaccinations were stopped. A quarter of America’s population had gotten the swine flu shots before it was stopped. I had an uncle who got Guillain-Barre Syndrome from the shot and was paralyzed for a period of time and was never the same physically. 

    Has the FDA dispensed with the safety standards formerly in place?

    This is why I oppose any mandate.

    I see it differently.  Your burden is proving your figures are accurate, and the process is valid.  Nobody, including you, knows enough to maintain either of those positions.  It may end up that even decades from now, we still won’t really know.

    If your assumptions are correct, shouldn’t there be a correlation between vaccination rate and infection rate? Instead, I have read in several places that data don’t show such a correlation.

    Thanks for linking this.  It was reported by Dr. Zubin Damania, aka ZDogg, over a month ago.  In the first video below, he and Dr. Monica Gandhi, an infectious diseases doc,  discuss viability of the virus in vaccinated people about 5 minutes in.  All in all, the entire hour long talk is worth a listen.  In fact, he’s worth listening to on a whole variety of subjects, Covid in particular.

    Jerry, again, I appreciate your effort to respond quantitatively. I’m still trying to decide how to approach the numbers, so I’m going to think out loud.

    Your comment #10 begins with this:

    Jerry Giordano (Arizona Patrio&hellip; (View Comment):
    I assume that Covid will be endemic, which basically means that you will get it eventually.

    That assumption that every unvaccinated person will get it eventually makes me uneasy. First, I’m not sure how it relates to the hundred million or so who are estimated to have already been infected, some of whom are no doubt not vaccinated. Secondly, if almost every unvaccinated person is going to get it no more than once (because of subsequent natural immunity), then I want to divide the probability of getting it by the estimated lifespan of the average American, to get a likelihood that, in any given year, an unvaccinated person will become infected.

    Then I want to multiply the estimated cost of an unvaccinated person being infected by the probability that, in any given year, that unvaccinated person will have become infected.

    As regards children, it would be nice to know if natural immunity is superior to immunization as a mechanism for preventing future infection. While I remain steadfastly opposed to mandatory vaccination for philosophical reasons, I’m not opposed to vaccination itself — except possibly in the case of children, where I’m unconvinced that vaccination is superior to natural immunity.

    The relative efficacy of past infection versus vaccination also interests me — and, again, particularly as it involves children. My kids all had chickenpox when they were young, but I understand that the varicella vaccine is now common; it’s mandated in my state for school children who do not have evidence of past chickenpox illness. I wonder about the long-term efficacy of the vaccine, and about the implications if it proves to be substantially less effective 30 or 40 years down the road than traditional childhood immunity from past infection, given that adult-onset chickenpox is, I think, generally more serious than the disease’s presentation in a child. And I wonder if something similar might be true of coronaviruses in general, and the Wuhan strain in particular.

    I might not have been clear about how this works. Based on my assumptions, each infected unvaccinated person will infect 2.6 other unvaccinated persons.

    Sorry, I don’t know. From my recollection early in the pandemic, the course of infection typically ran about 2-3 weeks, so I’d guess that it’s in this window.

    No. We don’t really know what it was before, either.

    I mentioned this in one of the comments above, but it was in the middle of a bunch of mathematical explanation, so it would be easily missed.

    The 2.6 transmission rate used in my calculation wasn’t the base transmission rate.  It was my estimate of the Delta variant R0 (6.5), multiplied by my assumption about the percentage of the population that is unvaccinated (40%).

    My quick research indicated that the original Covid R0 was estimated in the 2-3 range, with a large increase to the 6-7 range with the Delta variant.  I used the midpoint of this 6-7 range for my calculation.

    I might not have been clear about how this works. Based on my assumptions, each infected unvaccinated person will infect 2.6 other unvaccinated persons.

    Jerry, how long does this 2.6 transmission take?

    Sorry, I don’t know. From my recollection early in the pandemic, the course of infection typically ran about 2-3 weeks, so I’d guess that it’s in this window.

    So we’re now approaching the end of the second year. 104weeks/3weeks is about 34 times. That is a really big number. I stopped at 20 times and that was 124,550,930 if I’ve done the math correctly. The transmission rate may have been 2.6 at some points, but not always. Do we know what it is now?

    No. We don’t really know what it was before, either.

    I mentioned this in one of the comments above, but it was in the middle of a bunch of mathematical explanation, so it would be easily missed.

    The 2.6 transmission rate used in my calculation wasn’t the base transmission rate. It was my estimate of the Delta variant R0 (6.5), multiplied by my assumption about the percentage of the population that is unvaccinated (40%).

    My quick research indicated that the original Covid R0 was estimated in the 2-3 range, with a large increase to the 6-7 range with the Delta variant. I used the midpoint of this 6-7 range for my calculation.

    And yet it’s still possible that NONE of those numbers is actually correct.

    I just read that 95 percent of Americans aged 65 and older have been vaccinated. That is much, much higher than I had thought.

    They want to make it seem like most everyone is being delinquent. If that’s true, that’s a good sign and we can start taking away all the chains on the economy.

    My initial reaction was that this was too high of an estimate, HW, but I think that you’re (mostly) right. 

    The technical quibble is that the correct figure depends on what you mean by “vaccinated.”  The CDC dashboard (here) reports that among Americans 65 and over, 95.5% have received at least one vaccine dose, and 84.3% are fully vaccinated.

    Quibbles aside, that’s very good news.  Better than I thought.
