During the past year COVID-19 changed the lives of peo-
ple globally. Its threat to health and economy triggered an
unprecedented global research response, which resulted in
the speedy development of various vaccines as well as rapid
testing and assessment of medication. In the meantime, how-
ever, the healthcare system had to deal with surging numbers
of COVID-19 patients. The resolve to achieve progress in
research and the need to provide patient care under testing
circumstances triggered a variety of ethical difficulties.
Ethical challenges
The first three papers in the current issue highlight some of
the ethical questions triggered by COVID-19. Solbakk et al.
(2021) advance arguments against controlled human infec-
tion studies making a case for upholding well-established
research ethics guidelines, even under exceptional pandemic
circumstances. Da Silva et al. (2021) look at problems in
academic publishing such as keeping up the rigor of peer
review and the quality of editorial decision making when
dealing with a significantly increased manuscript flow and
facing the urgency to work faster rather than slower. They
advance six recommendations in order to minimize risks of
publishing questionable original research on public health
research related to COVID-19 (ibid.). Rashi (2021), finally,
tackles the dangers that health care workers and their fami-
lies are exposed to because of COVID-19. Should these risks
be accepted by health care workers? What are the justifica-
tions for the professional obligation to continue work under
circumstances of increased risk? When do working condi-
tions become unacceptably dangerous?

The case against exceptionalism
This editorial focuses on the first paper by Solbakk et al.
(2021) about human challenge trials, i.e., experiments where
human participants are intentionally exposed to pathogens.
The pandemic has triggered a debate about these studies
with advocates and opponents advancing a variety of argu-
ments (see ibid. table 2 for references). Yet, our authors are
not in favour of allowing any ethical exceptions or short-
cuts (ibid.). On the contrary, especially when it comes to
COVID-19 research they deem it pivotal to stick to existing
research ethics guidelines, the priority of the individual
principle being the most fundamental (ibid.). The inter-
ests of individual trial participants should always trump
those of society. Variations of this principle can be found
in the different versions of the Declaration of Helsinki and
in the UNESCO Universal Declaration on Bioethics and
Human Rights.
It remains unclear whether the authors assert that chal-
lenge trials are categorically unethical or whether their claim
is restricted to the specific case of COVID-19. The first
interpretation is suggested where they generically claim that
the primacy of the interests of individual research partici-
pants should be upheld whatever the circumstances. There
is no exception for times of crisis, or for instances where
societal interests are large (ibid.). The second interpreta-
tion is implied where they declare that the principle ...
prohibits the conduct of SARS-CoV-2 challenge studies at
the present time where the challenge virus would be the
native virus with full virulence and where there is no rescue
treatment yet available (ibid.). The two clauses indicate that
if the challenge virus were not fully virulent and/or there
was a rescue treatment, challenge trials might be acceptable
after all. Be this as it may, two questions must be clearly
distinguished.
