  -content: """
    \r\n
    <p>The media, naturally, said “thank you” for the rekindled fire, and threw gasoline on it: the story, and its attendant anxiety,&nbsp;<a href="https://www.cnn.com/2020/04/25/us/who-immunity-antibodies-covid-19/index.html" target="_blank" rel="nofollow noopener">were everywhere</a>.&nbsp;As my friend&nbsp;<a href="https://www.tesh.com/" target="_blank" rel="nofollow noopener">John Tesh</a>&nbsp;reminds me about media, “<em>if it bleeds, it leads</em>.”&nbsp;Sticking with my more flammable version of that sentiment, perhaps we may paraphrase: “if it combusts, it’s among the front-page musts.”</p>\r\n
    <p>As it happened, I was conferring with Tom Friedman at the time about&nbsp;<a href="https://www.nytimes.com/2020/04/28/opinion/coronavirus-sweden.html" target="_blank" rel="nofollow noopener">his latest column for the&nbsp;<em>New York Times</em></a>.&nbsp;When we spoke on Monday, I made this observation as part of our discussion: “you realize, of course, that if infection itself does not confer immunity, there is just about zero hope that any vaccine could.”&nbsp;</p>\r\n
    <p>Somehow, the WHO precaution left the world thinking that since infection may not confer immunity- we’ve got to have a vaccine.&nbsp;But that notion is just about oxymoronic, give or take the “oxy.”&nbsp;Tom asked me to explain why, and here’s that explanation, expanded.</p>\r\n
    <p>You can think of the immune system as your personal security team, on the job, round the clock, to defend you from dangerous intruders.&nbsp;So, let’s say your front door has been assaulted by some such intruders in broad daylight, faces fully on display.&nbsp;If those same folks turn up again, your security team will recognize them immediately as a threat, and take protective, defensive action accordingly.&nbsp;Forewarned is forearmed when it comes to immunity- and a good look at the threat in question is the priming event for both.&nbsp;In the case of a pathogen, that “good look” comes in the form of an infection.</p>\r\n
    <p>But what if instead of seeing the assailants, you only got a glimpse, or a narrow view?&nbsp;What if you just saw the back of a head, or the left shoulder, or a silhouette?&nbsp;All of these might help recognize the threat when these folks turn up again- but maybe not.&nbsp;Certainly, you would be less reliably forearmed than if you had seen the threat clearly, and fully.</p>\r\n
    <p>A vaccine is something like that partial view.&nbsp;Let’s keep this simple, and pretend that there are three&nbsp;<a href="https://www.cdc.gov/vaccines/index.html" target="_blank" rel="nofollow noopener">kinds of vaccines</a>&nbsp;(there are more, but these three cover the key considerations).&nbsp;The first is made using just a small part of a virus (or other pathogen), i.e., one or more proteins.&nbsp;The second is made using the whole virus, but killing it first.&nbsp;The third is made by “attenuating” the virus without killing it- in other words, beating it up enough so it is too punch-drunk to cause its native harm.&nbsp;</p>\r\n
    <p>Each of these is a stand-in for the native pathogen, intended to trigger a defensive response.&nbsp;But as with our perpetrators at the door- they do so with variable reliability.&nbsp;The more like the native infection, the stronger and more reliable the immune trigger.&nbsp;The less like the native infection, the less robust, generally, the immune trigger.&nbsp;Accordingly, the “protein only” vaccine is less potent than the killed pathogen vaccine, which is in turn less potent than the live, attenuated (“punch drunk”) vaccine.&nbsp;And none of these is as potent as…the infection itself.</p>\r\n
    <p><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5863094/" target="_blank" rel="nofollow noopener">Measles</a>&nbsp;is a good example.&nbsp;The vaccine (administered in combination, as the MMR) is among the best, because it is a live, attenuated vaccine.&nbsp;But even so, it appears to confer immunity that wanes over some number of years- as opposed to getting the measles, and recovering from it, which appears to confer robust immunity to last a lifetime (at the cost of far greater danger, of course).</p>\r\n
    <p>This story reverberates through the very invention of “vaccines,” the very reason we call them “vaccines,” which is derived from the Latin word for “cow.”&nbsp;</p>\r\n
    <p><a href="https://www.who.int/csr/disease/smallpox/vaccines/en/" target="_blank" rel="nofollow noopener">Edward Jenner</a>&nbsp;famously recognized that “milkmaids” who had recovered from cow pox were resistant to the far more dangerous small pox.&nbsp;The two were enough alike that exposure to the one primed the immune system to the other.&nbsp;The smallpox vaccine was born.&nbsp;Getting smallpox itself -and recovering from it- likely resulted in even more robust immunity against it, but thank goodness, cowpox exposure proved to be good enough.</p>\r\n
    <p>There is, of course, more to the vaccine story, and ways to work around roadblocks, involving haptens, and combination vaccines.&nbsp;Those details are beyond the scope of this telling.&nbsp;The general rule prevails: vaccines tend to confer lesser immunity than the infections they prevent.&nbsp;When the infections themselves don’t produce immunity- as is true, for instance, of herpes viruses and HIV- vaccines prove elusive at best, impossible at worst.</p>\r\n
    <p>I shared this perspective on Monday, and then it showed up&nbsp;<a href="https://www.usatoday.com/story/news/world/2020/04/28/coronavirus-covid-19-sweden-anders-tegnell-herd-immunity/3031536001/" target="_blank" rel="nofollow noopener">in&nbsp;<em>USA Today</em>&nbsp;on Tuesday</a>, courtesy of the chief epidemiologist for Sweden’s public health agency.&nbsp;<em>Deux beaux esprits se rencontrent.</em></p>\r\n
    <p>That all explains why the apparent message this past weekend, “we can’t rely on herd immunity, so let’s count on a vaccine,” was intrinsically nonsensical.&nbsp;But there’s good news to append: it was also almost certainly wrong.</p>\r\n
    <p>The WHO was not saying that we don’t get immunity from COVID19; they were simply saying we don’t have PROOF yet that we do.&nbsp;That’s true.&nbsp;We haven’t yet had time to aggregate data from people who (a) got the infection; (b) got over it; (c) made measurable antibodies to prove they were over it; (d) got re-exposed whether accidentally or on purpose; and then (e) were reassessed for infection.&nbsp;The WHO was not saying we have evidence against immunity; they were simply saying we don’t yet have decisive proof of immunity.&nbsp;</p>\r\n
    <p>But, in fact, there is a mass of support for immunity, including&nbsp;<a href="https://www.the-scientist.com/news-opinion/monkeys-develop-protective-antibodies-to-sars-cov-2-67281" target="_blank" rel="nofollow noopener">animal studies</a>, the apparent pattern of global epidemiology to date, and precedent with a wide range of related pathogens.&nbsp;This was my impression, but I ran it by&nbsp;<a href="https://directory.sph.umn.edu/bio/sph-a-z/michael-osterholm" target="_blank" rel="nofollow noopener">Dr. Michael Osterholm</a>&nbsp;whose perspective on all this I value greatly- and he concurred.</p>\r\n
    <p>The WHO announcement, in other words, was simply about absence of evidence.&nbsp;It was played up by the media as if indicating evidence of absence.&nbsp;They are entirely different.</p>\r\n
    <p>To be clear: there is no evidence against the prospect of herd immunity. And Sweden reports being well on its way.</p>\r\n
    <p>So, along with the reality check about immunity- I think we need one about the role of media in all this.&nbsp;If it bleeds, it leads – is, indeed, a media aphorism.&nbsp;So is: “comfort the afflicted, afflict the comfortable.”&nbsp;If you are getting comfortable with the idea that herd immunity is the way back to life as we formerly knew it- there’s incentive for the media to afflict it.</p>\r\n
    <p>Why?&nbsp;Just consider how we all crane our necks driving past a pile up.&nbsp;Morbid fascination seems to be wired into Homo sapien DNA.</p>\r\n
    <p>In addition, if our comfortable knowledge is forever afflicted, we remain perpetually uncertain, doubtful, and confused.&nbsp;What to do in those circumstances?&nbsp;Tune in tomorrow in the hope of answers.&nbsp;When tomorrow produces new confusion, tune in the next day.</p>\r\n
    <p>This is familiar terrain.&nbsp;The truth about diet and health hides in plain sight, obscured by media devotion to perpetuating confusion.&nbsp;In America,&nbsp;<a href="https://www.nytimes.com/2019/08/26/opinion/food-nutrition-health-care.html" target="_blank" rel="nofollow noopener">diet is the leading cause of premature death and chronic disease</a>, and is now an&nbsp;<a href="https://www.ehn.org/obesity-coronavirus-2645861896.html" target="_blank" rel="nofollow noopener">acute risk factor for severe COVID infection</a>&nbsp;into the bargain.&nbsp;Where diet most reliably optimizes immunity, defends acutely against infection, promotes vitality, and defends longitudinally against diverse assaults on years in life and life in years- it is not courtesy of a rogue theory, new fad, or morning show flavor of the week.&nbsp;It tends to be&nbsp;<a href="https://www.bluezones.com/" target="_blank" rel="nofollow noopener">time honored</a>, the&nbsp;<a href="https://oldwayspt.org/" target="_blank" rel="nofollow noopener">heritage-based</a>&nbsp;pattern of many generations.</p>\r\n
    <p>I am gratified that many people report loving my most recent book,&nbsp;<a href="https://davidkatzmd.com/books/how-to-eat-all-your-food-and-diet-questions-answered/" target="_blank" rel="nofollow noopener"><em>How to Eat</em></a>, co-authored with Mark Bittman.&nbsp;But I could not help but notice a theme among those who don’t: “<em>there’s nothing new here!</em>”&nbsp;Well…exactly, except the argument that there’s nothing new here!&nbsp;</p>\r\n
    <p>The most important news about diet for health is that there is no real news about diet for health.&nbsp;Pick&nbsp;<a href="https://www.dietid.com/" target="_blank" rel="nofollow noopener">any balanced dietary pattern</a>&nbsp;of real foods that has stood the test of time and you are reliably better off than feeding on any given pop-culture fad.&nbsp;There, we said it.&nbsp;Deal with it.</p>\r\n
    <p>I very much doubt COVID19 reinfection is much of a threat, and may be no threat at all.&nbsp;All signs suggest the opportunity to devise a safe,&nbsp;<a href="https://www.linkedin.com/pulse/out-blight-contagion-light-pandemic-pyramid-david/" target="_blank" rel="noopener">data-driven</a>&nbsp;course to the collective protection of herd immunity.&nbsp;That is&nbsp;<a href="https://www.truehealthinitiative.org/covid/" target="_blank" rel="nofollow noopener">the all clear</a>&nbsp;that lets grandparents hug their grandchildren once more; that is how we get our lives back.</p>\r\n
    <p>But the threat of perpetual reinfection with doubt, confusion, and worry- about COVID, or diet- with every news cycle, that’s another matter altogether.&nbsp;That is a clear, constant, and omnipresent danger.&nbsp;Beware, accordingly- and if you can, work on your immunity to it.</p>
