I&#8217;ve been thinking about what to do with this site ever since.  Some people do seem to find it useful&#8212;there have been nearly 25,000 visitors from all over the world since I started writing about vaccine efficacy, and I hope that those people found information that was valuable to them. To the extent that they did, it makes me somewhat proud, since I am a statistics person rather than a clinically-trained person, so having an impact in the COVID-19 pandemic, however small, feels like an achievement.  On the other hand, that same lack of clinical training means that I have to watch myself so as to write things that are justified by data, and keep from making wild, poorly-informed statements that do more harm than good.  I feel that so far I&#8217;ve stayed on the right side of that line.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">I may risk that balance in the next phase of this blog&#8217;s development.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">I plan to write a few observations of my own on the state of epidemic surveillance, epidemic modeling, and epidemic data, specifically with respect to the COVID-19 epidemic. I am doing this in part because I&#8217;ve been more deeply involved in data-driven epidemiological work, especially with respect to vaccine <em>effectiveness<\/em> (different from efficacy, because it characterized real risk reduction in real populations, rather than &#8220;pure&#8221; clinical properties of vaccines), culminating in a <a href=\"https:\/\/www.medrxiv.org\/content\/10.1101\/2021.09.18.21263783v3\">paper<\/a> demonstrating the possibilities of large-scale data analytics for epidemic surveillance and vaccine assessment.  In the process, I have become somewhat frustrated with the state of data curation and availability, but also with some of the model-premises underlying discussions of subjects such as vaccines, &#8220;breakthrough&#8221; infections, variants and their potential for vaccine escape, and so on.  In my opinion there is a great deal of intellectual confusion about these terms and concepts, and this confusion is feeding needless media and policy panic (and occasionally distracting from necessary panic). I feel I need a place to write down everything that I feel is (usually) subtly or (occasionally) grossly wrong about the public and scientific discussions of these issues. And I happen to have a more-or-less epidemiological blog. So I might as well do it here.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The cost of this change of direction is that I doubt that I can maintain the careful stance of defensible scientific statements that I tried to keep this blog to so far. Quasi-editorials on epidemiology by a statistically well-informed but barely-clinically-literate observer of the field should <em>by no means<\/em> be taken as authoritative refutations of anything, or in fact as anything more than spurs for further discussion by people working in the field, with whom I would be delighted to engage, and be told in exhausting detail all the reasons why what I&#8217;m writing is wrong-headed. I do listen, and try to learn. But I will also argue. I feel that I will have accomplished something useful if I at least bring to light a few unexamined or under-examined assumptions, and occasion a fruitful discussion of those assumptions, even if in the end I am the only one who feels educated by the process.  <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Nonetheless, I have a strong suspicion that I&#8217;ve seen some real issues&#8212;defects in how clinical data is created and curated and made available, defects of modeling, catastrophic terminological confusion&#8212;that need to be brought into the light. I&#8217;ll be discussing these in a series of posts.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What&#8217;s This About?
