SMIS - Association of Microbiologists, Immunologists and Statisticians

SMIS - Sdružení mikrobiologů, imunologů a statistiků (the Association of Microbiologists, Immunologists and Statisticians) is a Czech professional association that brings together specialists from microbiology, immunology and statistics. Its stated motivation, described on its official website, arose from the COVID-19 pandemic: the group argues that there is a fundamental difference between reality itself and the picture of reality obtained through various measurements. A positive PCR test result, for example, does not necessarily mean a person is ill, and a negative result does not necessarily mean a person is healthy. The association's central intellectual theme is Bayesian logic, which it describes as a technical term for sound common sense. SMIS argues that if laboratory and diagnostic data are to be used as a basis for correct decisions, they must be evaluated with an appropriate degree of uncertainty. The organization therefore positions itself at the intersection of laboratory medicine and statistical methodology, advocating for probabilistic reasoning in medical testing and public-health decision-making. SMIS maintains an active online presence at smis-lab.cz, where it publishes articles, commentary and news. Its content has addressed topics such as the interpretation of PCR testing, the handling of COVID-19 data by institutions such as the CDC, and questions surrounding mRNA vaccine safety, including reports of myocarditis. The association also engages with the Czech statistical community; its members have participated in events such as the Olomoucké statistické dny (Olomouc Statistical Days), held at the botanical garden of the Faculty of Science of Palacký University and organized by the Czech Statistical Society together with the Department of Mathematical Analysis and Applications of Mathematics. As a professional association rather than a commercial manufacturer, SMIS does not sell physical products; its output consists of expert commentary, educational content and contributions to professional debate. It operates primarily in the Czech Republic and communicates in Czech.

SMIS - Sdružení mikrobiologů, imunologů a statistiků is a Czech association whose public activity, as described on its official website, was galvanized by the COVID-19 pandemic. The association explains its origins by pointing to a lesson the pandemic made vivid: there is a difference between reality itself and the image of reality produced by measurement. A positive PCR test does not necessarily mean a person is sick, and a negative test does not necessarily mean a person is healthy. SMIS argues that laboratory and diagnostic data can only support correct decisions if they are evaluated with a proper measure of uncertainty, and it identifies Bayesian logic — which it calls a technical term for sound common sense — as the framework for doing so. From this starting point, SMIS has built an online publication platform at smis-lab.cz through which it distributes articles, commentary and news aimed at professionals and the interested public. Its output has focused heavily on the interpretation and misuse of COVID-19 data. One recurring theme has been criticism of how institutions such as the U.S. Centers for Disease Control and Prevention handled pandemic statistics; an SMIS article titled 'deaths by rule of three' is cited years later by the association's contributor Tomáš Fürst in a piece arguing that American healthcare during COVID-19 was led by even greater ignoramuses than previously thought. Another strand of SMIS content concerns vaccine safety. In September 2026 the site published an article by Zuzana Krátká reporting that the first cases of serious health problems and deaths among people vaccinated with mRNA vaccines had appeared already in manufacturers' clinical trials, but increased significantly after vaccination began in Israel, and that an early Israeli warning about myocarditis was ignored by the world health agency; the article cites Israeli authors Yaffa Shir-Raz and Yaakov Ophir. SMIS also participates in the Czech statistical community. In September 2026, the Olomouc Statistical Days were held on 10–11 September at the botanical garden of the Faculty of Science of Palacký University, organized by the Czech Statistical Society together with the Department of Mathematical Analysis and Applications of Mathematics. The opening section of the conference, reported on the SMIS site, pleased supporters of the association, indicating that SMIS members are present in national statistical forums as well as in online commentary. The association's precise founding date, formal legal structure, membership numbers and leadership are not documented in the available evidence. What is clear is that SMIS operates as a Czech-language professional and advocacy association, active online and engaged with both the statistical and medical communities in the Czech Republic.
