Protecting vulnerable populations in research isn’t just the right thing to do—it’s essential for ensuring ethical integrity and credible outcomes.
Neglecting these safeguards can lead to significant harm for participants and lasting damage to organizations. Let’s explore who these vulnerable groups are, why they need extra care, and how researchers can implement best practices to protect them.
And a reminder that vulnerable populations in research is a module in our PPRE training. If you’re interested in learning more, you can find more information here.
Who are vulnerable populations?
Vulnerable populations are individuals who are more likely to experience harm or exploitation during research. According to the U.S. Department of Health and Human Services, these groups include but aren’t limited to:
- Pregnant women, fetuses, and neonates: Risks in biomedical research can affect both mother and child.
- Prisoners: Limited autonomy makes them more susceptible to coercion.
- Minors (under 18 years old): Their ability to comprehend risks complicates informed consent.
- Individuals with impaired decision-making capacity: Cognitive challenges make it harder to evaluate risks and benefits.
- Economically and educationally disadvantaged individuals: Financial incentives to take part in research might create undue influence on participation.
- Native/Indigenous populations: Historical trauma, systemic oppression, limited healthcare access.
- Folks for whom English is a second language or are non-English speaking:
Language barriers, limited resources, difficulty accessing essential services.
- Elderly individuals: Physical vulnerabilities, social isolation, financial insecurity.
- Those with chronic health conditions: Ongoing medical needs, financial burdens, reduced mobility.
- Those with limited literacy: Difficulty accessing information, job barriers, reliance on others.
Recognizing these groups is the first step to creating ethical research frameworks that prioritize their safety and dignity.
Why is protection so important?
Protecting vulnerable populations isn’t just about avoiding harm—it’s about ensuring the research is ethical, impactful, and trustworthy.
When we do research and evaluation IN partnership with people, we reduce exploitation and increase trust. There’s more integrity, validity, and reliability and ultimately better data = better insights = better action.
And on a pragmatic level, this also means your data is more likely to result in landing the grants your organization deserves.
- Preventing exploitation: Safeguards ensure participation is voluntary and informed, not coerced by circumstances or incentives.
- Building trust: Ethical practices create confidence in both the research process and its outcomes, benefiting participants and the community.
- Strengthening data integrity: When research is conducted ethically, results are more reliable and applicable to broader populations.
Without these protections, the consequences can be severe—for both participants and the organizations conducting the research.
What happens when protections are overlooked?
Neglecting the safety and rights of vulnerable populations can have far-reaching consequences:
- Harm to participants: Physical, psychological, and social harm can occur. Participants may lose trust in research altogether, impacting their willingness to engage in future studies. They may share their concerns with other people in their community, creating a resistance to research within the entire population.
- Legal and financial repercussions: Lawsuits, hefty fines, and loss of funding can derail an organization’s work. Pfizer’s 1996 clinical trial in Nigeria violated ethical standards by failing to obtain informed consent and exploiting vulnerable populations, resulting in child fatalities, long-term harm, lawsuits, and a $75 million settlement.
- Reputation damage: Once trust is broken, it can take years to rebuild, affecting partnerships, public perception, and the ability to secure grants or participants.
Remember, these protections are not just for the participant – they are for you, the researcher, your organization, and the integrity of your work.
How to conduct ethical research with vulnerable populations
When we make the research process better for vulnerable, historically excluded, marginalized, and harmed groups — it makes the experience better FOR EVERYONE. It’s just good practice.
Ethical research is about more than compliance—it’s about fostering trust and prioritizing the well-being of participants. Here’s how:
- Obtain clear informed consent: Use accessible language and methods to ensure participants understand what they’re agreeing to.
- Implement extra safeguards: Use community advisory boards to protect participants’ rights and well-being.
- Design thoughtful incentives: Compensation should recognize participants’ time and effort without creating undue pressure to participate. You might think you are being super generous with an incentive (and you may be), but consider whether the single parent, broke college student, or dislocated worker you are asking to participate can afford NOT TO participate.
- Customize your approach: Every population is different. Tailor your research methods to reflect the specific needs and vulnerabilities of your participants. Don’t know how? Ask someone that regularly works with that population, or is themself a member of that population (or both!).
