The aim of this lesson was to objectively analyze the role of vaccines in infectious disease control at a time when vaccine mistrust threatens to undermine the global public health model inherited from the 20th century, of which vaccines are a major pillar. This lesson examined the roots of this mistrust, noting, for example, the sociological sensitivity to mass vaccination campaigns such as those against hepatitis B in the 1990s and against the H1N1 flu in 2009. This resonated as an anticipation of the concerns generated by the rapid development of a vaccine against Covid-19, destined for universal use, in order to effectively control the pandemic. This lesson had particularly emphasized the uncertain place of vaccination against an emerging epidemic/pandemic, insofar as the " scientific time frame " of development was not compatible with the urgency of pandemic control. It did, however, open the door on the basis of the recent accelerated development of a vaccine against the Ebola virus, but did not anticipate the extraordinary development of mRNA vaccines against SARS-CoV-2, integrating vaccination as a solution to the control of an emerging pandemic.
