In an invigorating comparative and interdisciplinary reconsideration of the role of different types of medical counting, this wide-ranging bilingual volume takes us from the mortality tables of the eighteenth century to the movement for evidence-based medicine in our own day. Culled from the proceedings of La quantification dans les sciences médicales et de la santé: perspective historique held at the Musée Claude-Bernard in France in 2002, Body Counts moves beyond the usual emphasis on public health and clinical medicine to include the central role of numbers in laboratory work and medical instrumentation. Body Counts provides an innovative, historical, and sociological account of the functions of quantification.

Pertussis vaccination policy varies across Europe, not only in the type of vaccine—whole cell (wP) vs. acellular (aP1/2/3/5)—but also in the schedule and recommendation for parents. This study aims to investigate the determining factors for the type of vaccine, immunization schedule and maternal immunization recommendation. From March to May 2019, experts in national health agencies and major academic or research institutions from Denmark, France, Poland, Sweden and the UK were invited to a semi-structured interview. Thematic analysis was performed on the transcripts using a codebook formulated by three coders. Inter-coder agreement was assessed. Fifteen expert interviews were conducted. The identified driving factors for pertussis vaccine policy were classified into three domains: scientific factors, sociological factors, and pragmatic factors. The determining factors for the type of vaccine were prescriber’s preference, concern of adverse events following immunization (AEFI), effectiveness, and consideration of other vaccine components in combined vaccines. The determining factors for infant schedule were immunity response and the potential to improve coverage and timeliness. The determining factors for maternal immunization were infant mortality and public acceptability. To conclude, socio-political and pragmatic factors were, besides scientific factors, important in determining the pertussis vaccine type, schedule of childhood immunization and recommendations for parents.

The severity and endemicity of malaria declined gradually in Europe until WWI. During and after the war, the number of malaria cases increased substantially and peaked in 1922-1924. This prompted the Hygiene Commission of the League of Nations to establish a Malaria Commission in 1923 to define the most efficient anti-malaria procedures. Additionally, between 1924 and 1930 there were several international meetings and collaborations concerning malaria, which involved the main institutes of parasitology and the Rockefeller Foundation. The Commission reports, the guidelines for anti-malaria campaigns and the scientific programs which came out of these meetings and collaborations are analyzed in the present paper.
