High-level biocontainment laboratories: risks and necessity for society

Abstract

Advancements in the biological sciences have made it possible to manipulate life forms in unprecedented ways. Recognizing the possible dangers connected with this activity, as well as with work involving natural pathogens, countries have promoted the building of High Safety and High Containment Laboratories, classified as Biological Safety Levels 3 and 4. In this article I briefly summarize the major features of these laboratories, exemplify some of the research that they host, highlight the possible dangers, and argue for the opportunity of a reduction of possibly dangerous research, and for more transparency and openness about activities that imply risks not only for those involved, but for human and environmental health as well.
