In light of the present COVID-19 crisis, we are seeing an intense specialise in the question of how soon we will make a vaccine available to guard the general public from the novel SARS-CoV-
2 coronavirus. Typically, developing a vaccine against any illness can take years and many dollars, and in some cases we still might not have complete success  for instance , we've a vaccine for influenza, but it's not a universal vaccine; there's no vaccine for HIV, even after decades of research.
According to the WHO, HCTs are “trials during which participants are intentionally challenged (whether or not they need been vaccinated) with an communicable disease organism. This challenge organism could also be on the brink of wild-type and pathogenic, adapted and/or attenuated from wild-type with less or no pathogenicity, or genetically modified in some manner.”
The purpose of an HCT is that the same as that of animal challenge studies and models, with the added advantage of studying the potential drug vaccine candidates directly in humans during a controlled environment. This enables the research community to screen potential drug vaccine candidates and move the foremost promising candidates to larger trials .
Public engagement can help to assess the local acceptability of human challenge studies, maximise transparency by responding to any community concerns, and elucidate the potential effect of research on the community .
The ethical acceptability of COVID-19 human challenge studies would be in part contingent on there being potential benefits (for public health or for participants) that outweigh the expected risks. Important potential benefits to public health include those arising from the acceleration of vaccine development, the development of more effective vaccines, and the improvement of relevant scientific knowledge that can inform public health practice results regarding correlates of protection or the risks of transmission from asymptomatic individuals .
All of this could be done supported what challenge agent the Challenge Unit plans to figure with, so it's important to possess agile facilities which will adapt to the various requirements of various organisms being studied. It is additionally important for the operational team to understand the bounds of its facilities and resources, and to never comply with study an organism that's incompatible with the grade of the facilities. Know your expertise, but also know your limitations .
