Objectives In this study, we aimed to measure the awareness, acceptability and perceptions of current issues in biosecurity posed by infectious diseases dual-use research of concern (DURC) in the community. DURC is conducted today in many locations around the world for the benefit of humanity but may also cause harm through either a laboratory accident or deliberate misuse. Most DURC is approved by animal ethics committees, which do not typically consider harm to humans. Given the unique characteristics of contagion and the potential for epidemics and pandemics, the community is an important stakeholder in DURC.

Design Self-administered web-based cross-sectional survey.

Participants Participants over the age of 18 in Australia and 21 in the USA were included in the survey. A total of 604 participants completed the study. The results of 52 participants were excluded due to potential biases about DURC stemming from their employment as medical researchers, infectious diseases researchers or law enforcement professionals, leaving 552 participants. Of those, 274 respondents resided in Australia and 278 in the USA.

Outcomes Baseline awareness, acceptability and perceptions of current issues surrounding DURC. Changes in perception from baseline were measured after provision of information about DURC.

Results Presurvey, 77% of respondents were unaware of DURC and 64% found it unacceptable or were unsure. Two-thirds of respondents did not change their views. The baseline perception of high risk for laboratory accidents (29%) and deliberate bioterrorism (34%) was low but increased with increasing provision of information (42% and 44% respectively, p<0.001), with men more accepting of DURC (OR=1.79, 95% CI 1.25 to 2.57, p=0.002). Postsurvey, higher education predicted lower risk perception of laboratory accidents (OR=0.56, 95% CI 0.34 to 0.93, p=0.02) and bioterrorism (OR=0.48, 95% CI 0.29 to 0.80, p=0.004).

Conclusion The community is an important stakeholder in infectious diseases DURC but has a low awareness of this kind of research. Only a minority support DURC, and this proportion decreased with increasing provision of knowledge. There were differences of opinion between age groups, gender and education levels. The community should be informed and engaged in decisions about DURC.

Strengths and limitations of this study

  • To the best of our knowledge, this research article is the first to survey the general community regarding dual-use research of concern and virus gain of function research.

  • This study measured all responses at baseline and following the provision of information to measure changes in acceptability and risk perception.

  • These results may not be generalisable as the study population was limited to respondents living in the USA and Australia.


Dual-use research of concern (DURC) is research that is intended to benefit humanity but may also inadvertently or deliberately be used to cause harm. The term DURC is applicable to many technologies, such as artificial intelligence, drones or biology. For this study, we focused on infectious diseases DURC. DURC in infectious diseases can cause harm generally by two mechanisms: a laboratory accident or deliberate release of a pathogen. An example of DURC is influenza gain of function research (GOF), where viruses are genetically engineered to alter key characteristics and enhance their pathogenicity or transmissibility. This is sometimes referred to as ‘GOF research of concern’ (GOF-oc). GOF-oc has been controversial since 2011, when two research groups planned to publish methods to engineer an H5N1 avian influenza virus to make it transmissible in mammals.1 2 The US National Science Advisory Board for Biosecurity (NSABB) recommended that molecular details be redacted from the final manuscripts,3 before researchers self-imposed a voluntary moratorium on such research,4 and the National Institutes of Health (NIH) paused all funding for GOF-oc.5 After intense debate, NSABB allowed the methods of the two Influenza A H5N1 GOF-oc studies to be published in 2012.6 A further pause in funding occurred in 2014, but was lifted in December 2017.7 DURC, however, is not limited to research on influenza. In 2017, scientists recreated an extinct Orthopoxvirus closely related to variola virus (smallpox), and published their methods in 2018.8 The potential impact on the community of smallpox re-emergence would be high due to an increasingly unvaccinated population and rising levels of immunosuppression.9

Proponents of DURC and GOF-oc argue that such research is essential for understanding the causal relationship between mutations and the pathogenicity of lethal influenza viruses, which could aid pandemic surveillance and control efforts.4 Others, however, feel the risk of laboratory accidents is unacceptable, as is the potential for bioterrorism, due to ease of access to DURC methods and rise in poorly regulated Do It Yourself (DIY) laboratories.10–13 Furthermore, the threat that sensitive pathogens may be misappropriated by an ‘insider’, that is, scientists or security personal that work with or safeguard sensitive pathogens, is recognised as one of the most significant risks of biological research and creates new vulnerabilities in global biosecurity.14 Legislation for biosecurity exists within nations and internationally but is inconsistent and often unenforceable. The WHO’s 2005 International Health Regulations (IHR) and the Biological Weapons Convention are relevant, but do not address the governance of DURC.15 16 Individual countries have gene technology regulations similar to the Cartagena Protocol, developed for genetically modified plants and livestock, with a focus on regulating international trade in genetically modified organisms, rather than DURC.17

To date, the debate about DURC has largely occurred within the scientific community.18 19 While some parties advocate freedom of science,20 and others urge for caution,21 22 the community has largely been absent from the debate. The community, however, is an important stakeholder in the case of infectious diseases DURC because of contagion and the potential for epidemics. Infectious diseases DURC pose a unique ethical problem to the principles of the declaration of Helsinki on conduct in medical research, in that DURC is performed on animals, and undergoes animal ethics approval, but potential harm may result in humans who were never consulted nor consented to the research.23 Further, an experiment done in one country may harm people in another who were unaware of the research. The community has not been engaged in this debate, and there is little understanding of the views of community members on DURC in general. The US has taken more steps to deal with DURC issues than any other country, such as establishment of NSABB,24 a risk benefit analysis on DURC,25 the establishment of a Blue Ribbon Biodefense Panel and a National Biodefense Strategy.26 The US Department of Health and Human Services also provides guidelines to researchers on DURC.27 None of these measures have been taken in Australia, which has instead approved the use of CRISPR Cas 9 SDN-1 (clustered regularly interspaced short palindromic repeats, site directed nuclease) technology for microorganisms,28 29 and relaxed export controls on DURC technologies.30 As scientists, we have a responsibility to make ethical decisions for the benefit of communities, but we should endeavour to engage the community in far reaching debates such as this. This recognition is reflected in the inclusion of community representatives on many human research ethics committees. In this study, we aimed to measure the awareness, acceptability and perceptions of current issues in biosecurity posed by DURC in the community as a stakeholder in both the potential benefits and risks of DURC. We also sought a comparison of community awareness between Australia and the USA which has quite different policy and risk management environments.


Participants and sample size

The study was designed to measure knowledge and attitudes of the community in the USA and Australia about DURC, and changes in perception following the increasing provision of information related to DURC. A sample size of 517 respondents was required to detect knowledge of DURC of 15% with 95% confidence and 85% power. The survey was conducted in 2017 by Survey Sampling International (SSI), LLC who were provided with a representative sampling frame from the researchers by age, gender and other sociodemographic characteristics of the Australian and United States population. The two countries were selected because of very different approaches to DURC, with the US taking a risk analysis and regulatory view and Australia allowing more freedoms to researchers as explained above. Participants were selected randomly from the specified sampling frame. An algorithm was used to randomly select participants from general population representative survey panel members (n=400 000) according to the following demographic splits with +/-5% leeway for age >18 years (Australia) and >21 years (USA) and equal gender representation. The sampling method used by SSI does not provide data on non-response. A presurvey questionnaire included questions to confirm age and location, and current employment, excluding those who were medical researchers, infectious diseases researchers or law enforcement professionals, due to potential biases about DURC. Respondents were also excluded if they were under 18 in Australia or 21 in the USA. The maximum age of participants was not a restricting factor. We oversampled by 35 subjects to allow for non-response or non-completion.

Study design

We designed a cross-sectional web-based survey characterising respondent’s awareness, acceptability and perceptions of risk around DURC among residents in Australia and the USA with changes in attitudes in the same individuals recorded over the course of the survey (before and after information provision). At baseline, respondents were asked about their awareness and acceptability of DURC and other related biosecurity matters such as the storage of security sensitive pathogens and ‘Insider Threat’ answering ‘yes’, ‘no’ or ‘unsure’. Respondents were also asked for their perception of risk to their personal health and the risk of an accidental and deliberate biosecurity incidents resulting from scientific research methods in genetic engineering and synthetic genomics of infectious pathogens from negligible to very-high risk. They were also asked about DIY biology.11 Participants were presented with factual and non-partisan background information on current issues and case studies in DURC and biosecurity at each stage and the same questions were repeated at different stages to measure if perception changed overtime. The survey is included as online supplementary appendix 1.

Statistical analysis

The analysis measured change in attitudes in the same, individual participants before and after provision of information (paired responses). We conducted univariable and multivariable binary logistic regression investigating the relationship between independent demographics variables age, education, gender, country and economic status (as measured by home ownership) on responding ‘Yes’ or ‘No or Unsure’ to questions on DURC acceptability, threat and security (Survey online supplementary appendix 1). Univariable and multivariable ordinal logistic regression was used to measure the relationship between the same independent demographic variables and rankings of risk perception on a six-point scale assuming a linear increase between risk levels. For both the multivariable binary and ordinal logistic regression, only independent variables significant in the univariable analysis were included for control in the multivariable analysis. Demographic variables were coded with Male, Australia and Home ownership equal to 1, and Education ranked on a four-point scale. Age was left as reported on a continuous integer scale. To measure significant changes between questions asked presurvey and postsurvey, we conducted McNemar’s tests for paired dichotomous data where ‘No’ and ‘Unsure’ were grouped as one, while for questions with ordinal risk ratings, we conducted a non-parametric Wilcoxon signed rank test. All statistical analyses were performed using R including descriptive statistics. Significance was defined where p values <0.05. No data were missing as all questions were required to be answered. Incomplete surveys due to withdrawal were excluded.


Demographics and difference between American and Australian survey responses

The demographics of survey participants by country can be seen in table 1. There was no evidence of differences in the demographics of respondents in the USA and Australia except for education (p=0.002). At baseline, 23.2% (n=128/552) of all respondents indicated awareness of DURC (see online supplementary table S1). There was weak evidence that awareness was slightly higher in the USA compared with Australia (26.6% vs 19.7%, p=0.066). Only 36.2%, (n=200/552) believed the possible benefits of DURC outweighed the risk while almost half of respondents (49.5%, n=273/552) believed genetic engineering research of infectious organisms such as viruses might be a threat to their health. A majority (62.7%; n=346/552) believed the risk of a laboratory accident resulting in an epidemic to be moderate or higher, and 63.3% (n=349/552) rated the risk of bioterrorism as moderate or higher. There were some differences between respondents based in Australia versus the USA: there was very strong evidence that Australians were less accepting of DIY Bio Labs compared with Americans (p<0.001) although acceptance overall was very low in both countries: 3.6% (n=10/274) in Australia and 13.3% (n=37/278) in the USA. At baseline, Australians rated the risk of laboratory accidents involving engineered viruses lower than Americans (φC = 0.17, p=0.002). Additional baseline results stratified by country can be seen in online supplementary table S1.

Change from baseline attitudes to DURC postsurvey

Not all respondents changed their position following exposure to the background information. Approximately 66% (367/552) of respondents did not deviate from their original responses regarding DURC acceptability whether positive, negative or unsure. Of those, the largest fixed group thought DURC remained unacceptable (36.5%, n=134/367), followed by those who thought DURC remained acceptable (34.6%, n=127/367). Around 53.5% (106/198) of those who were unsure regarding DURC acceptability remained unsure at the end of the survey, but the remainder changed their view to positive (9.6%, n=19/198) or negative (36.8%, n=73/198).

Following the provision of further information, there was evidence that negative attitudes towards DURC increased in all question categories, with a corresponding decrease in the percentage of respondents who were unsure or had positive attitudes towards DURC. Almost 20% of respondents’ (n=109/552) perception had changed negatively about DURC by the end of the survey. The majority (51.8%, n=286/552) of respondents said they were not confident that engineered viruses were securely stored, compared with 34.8% (n=192/552) at baseline; the highest absolute percentage change of +17% (p<0.001). Forty-four per cent of respondents (n=243/552) also believed that in general DURC was unacceptable when posed as the engineering of influenza viruses (+16.1% from baseline, n=154/552, p<0.001), while 54.7% (n=302/552) felt that genetically engineered organisms might be a threat to their health (+5.2% from baseline, n=273/552, p=0.02) by the end of the survey. Percentage changes for respondent’s attitudes towards DURC can be seen in figure 1 with corresponding values and p values in online supplementary table S2.

Change from baseline perception of risk

When asked to rate the risk of a biological incident resulting from a laboratory accident or intentional bioterrorism, perceptions of risk increased significantly from baseline (see online supplementary table S2) corresponding to increases in very high/high risk ratings while moderate and low/negligible perceptions of risk decreased (figure 2). Those who were unsure also decreased from baseline. The largest percentage increase in risk perception from baseline (+13.2% from n=161/552, p<0.001) occurred in those reporting very high/high risk of a laboratory accident causing a biological incident postsurvey (n=233/552). This was followed by a 10.3% (n=188/552), p<0.001) increase in those reporting very high/high risk of bioterrorism postsurvey (n=245/552). Percentage change in DURC risk perception can be seen in figure 2. In general, negative changes in risk perception (increasing risk) was less pronounced than negative changes in attitudes towards DURC.

Table 2 shows the association between respondent demographics and responses presurvey and postsurvey identified by the multivariable logistic and ordinal regression analyses. Postsurvey, men were more likely to believe DURC was acceptable (OR=1.79; 95% CI 1.22 to 2.63; p=0.003), that pathogens associated with DURC were securely stored (OR=2.02; 95% CI 1.36 to 3.02; p=0.001), and rated the risk of laboratory accidents (OR=0.69; 95% CI 0.51 to 0.94; p=0.02) and bioterrorism (OR=0.56; 95% CI 0.42–0.77; p=0.001) lower compared with women. Whereas increasing age predicted greater negative or uncertain sentiments towards DURC such as acceptability (OR=0.99; 95% CI 0.98 to 0.99; p=0.007) and the storage of DURC pathogens (OR=0.98; 95% CI 0.97 to 0.99; p=0.002) when controlling for other variables. However, increasing age was also associated with lower rating of the risk of laboratory accidents (OR=0.99; 95% CI 0.98 to 0.99; p=0.02) but not bioterrorism (OR=0.99; 95% CI 0.99 to 1.01; p=0.069; see online supplementary table S3). Higher Education was associated with rating the risk of laboratory accidents (OR=0.56; 95% CI 0.34 to 0.93; p=0.023) and bioterrorism (OR=0.48; 95% CI 0.29 to 0.80; p=0.004) lower postsurvey more than age. Some predictors lost or gained significance presurvey or postsurvey, whereas others remained statistically significant at both time points, for example, male acceptability of DURC and belief in the secure storage of pathogens (table 2). Furthermore, some demographics were only associated with the outcomes in the univariable analysis (see online supplementary table S3), while others remained significant when controlling for other variables in the multivariable analysis (table 2), for example, higher education and residing in Australia regarding DURC acceptability.

The majority of the general community surveyed in this research was not aware of DURC, and at baseline felt that engineering of pathogens was unacceptable. Almost half also felt that infectious diseases DURC may be a threat to their health. The baseline perception of risk of laboratory accidents or unsafe storage of pathogens in laboratories was low and only a minority felt the risk of bioterrorism was high.

Exposure to factual background information on DURC and case studies changed risk perceptions among one-third of community members, with the other two-thirds having fixed views. By the end of the survey, those who felt the engineering of pathogens was unacceptable increased significantly by 16% (p<0.001). Increasing awareness of DURC as the survey progressed demonstrated increasing confidence in attitudes, as indicated by the decreasing percentage of unsure responses in every question category by the end of the survey. At baseline, negative attitudes towards DIY bio laboratories was very high with a majority believing current arrangements of self-regulation were unacceptable. This may be reflective of greater trust in government regulation of DURC or the belief that these types of research should be restricted to official research institutions.

To date, the debate about DURC has largely occurred within scientific and regulatory committees.31 32 As the primary stakeholders in the risks and benefits of infectious diseases DURC, any decision-making process involving DURC should involve the community. Many ethics committees have a community representative to weigh the risk of research to the community against the potential for community benefit. However, a sole lay person among experts and scientists may not be in an adequately informed position nor feel empowered enough to question DURC. We were unable to identify any other studies of general community attitudes to DURC. A paper-based survey of 933 medical students in Pakistan showed that almost 60% had never heard of DURC, and that medical students felt they should receive training on the subject.33

This study has implications for DURC research and for policy. In medical research, informed consent is required by persons who may be harmed, usually limited to subjects in research studies. Often DURC is conducted in animals,1 2 and thus undergoes approval through animal ethics committees. Such committees typically do not consider risk to humans of the research. Further, epidemics and pandemics that arise from such research either through accidental or deliberate release could impact people around the world who were never informed about the research nor consented to it, raising a new dimension to research ethics.34 Our results show that the community in both Australia and the USA is largely unaware of DURC and feel it may be a threat to their personal health. Research ethics committees reviewing animal DURC should include consideration of harm to humans. For policy makers, alternatives to DURC should be considered. Infectious diseases DURC such as avian influenza GOF-oc has recently expanded to include other high mortality serotypes such as avian H7N9.35 By studying the genetic changes required to increase avian influenza transmissibility in mammals, these studies aim to preempt pandemics in the future.36 37 The results of some of these GOF-oc studies have already been incorporated into government pandemic risk assessment frameworks; however, the generalisability and predictive power of these results have been frequently criticised.38 39 A US government-funded report released in 2015 concluded that the benefit and risk of GOF-oc remained inconclusive,40 while a European Union commissioned report echoed similar conclusions.41 42 Alternatives to genetic engineering for medical therapies include gene silencing, with the first such drug, ONPATTRO (Patisiran), approved in 2018 by the US Food and Drug Administration.43

Other approaches to mitigating the risk of unnatural epidemics include the development of threat assessment, surveillance and detection systems. Examples include profiling of ‘lab-specific’ infectious disease signatures using deep learning convolutional neural networks.44 Additional non-pharmaceutical alternatives include the development of new and innovative personal protective equipment (PPE), optimising logistical and operational integration, and the establishment of agile national and international oversight mechanisms.45 46 This research may also have impact in preventing and mitigating future pandemics with no additional risk to the community compared with GOF-oc. Allowing the community to critically evaluate the risks and benefits of GOF-oc while being informed of potential alternatives ensures principles of consent in medical research are maintained. The risk of infectious diseases DURC to the community via accidental release or insider threat cannot be dismissed, while the benefits remain inconclusive.23 47

The strengths of this study include being the first study we are aware of to explore general community views on DURC, and the use of a before-and-after design to measure baseline views and changes following provision of information. The use of an established online community surveying methodology with a representative community sample is also a strength, as it is more convenient for participants and provides similar representativeness and results to paper-based surveys.48 The limitations of this study include the potential of bias in the framing of the survey, but we aimed to minimise this in our design. The small sample size is also a limitation, and larger studies would be useful as a follow-up. The method of the online survey using SSI precluded collection of information on non-response, which could introduce non-response bias. However, in the sample, we were able to measure changes in attitudes before and after provision of information.

The community is an important stakeholder in infectious diseases DURC but has a low awareness of this kind of research. Only a minority support DURC, and baseline perceptions of risk of laboratory accidents, unsafe storage of pathogens and bioterrorism increased with the provision of knowledge. There is very little community support for self-regulation of DIY biology, which represents another area of concern. The net-benefit argument supporting DURC remains inconclusive, and more risk analysis research is required around this question. Engaging with the community should be priority for future research and for regulatory agencies. More research is needed in this area, and also on the views of specific stakeholder groups such as researchers, policy makers, security, defence and law enforcement personnel.
