Infectious agents are still in circulation in different parts of the world, and globalization, with travel on the agenda, migration, and poverty, makes vaccination a tool more than ever necessary. Despite the impressive number of studies carried out since the virus was first characterized, there are still many unknowns about this disease. Moreover, it is precisely these unknowns that fully justify the very different conceptual and technological strategies that are currently pursued in the preparation of vaccines against COVID-19. Due to the short development time and the novelty of the technologies adopted, these vaccines will be deployed with several unresolved issues that only the passage of time will permit to clarify. Technical problems connected with the production of billions of doses and ethical ones connected will be needed to ensure equitable global access, protection of diverse subjects, and immunity against viral variants.
