While there has been much discussion about how effective various public health measures are against COVID-19, there has been less discussion about the moral and ethical issues raised by the pandemic. What are our moral obligations in the face of COVID-19?

To discuss these issues we reached out to Karey Harwood, a bioethicist and associate professor of religious studies at NC State. Harwood’s work focuses on ethical issues related to biomedicine and biomedical technologies, as well as how religious beliefs inform our understanding of these issues.

This post is part of a series of Q&As in which NC State experts address questions about the vaccines on issues ranging from safety to manufacturing to distribution.

The Abstract: Does anyone have a moral obligation to get vaccinated or wear a mask?

Karey Harwood: Yes, people who are healthy enough to be vaccinated have a moral obligation to get vaccinated.

Simply put, no person is an island. Our immunity to disease is a shared resource that we all have a responsibility to protect. It can be difficult in a highly individualistic society to find ways to think about collective responsibilities. But really, it’s not at all strange or radical to think about responsibilities that we willingly share for the good of the human community. What’s strange is how Americans have grown alienated from these ideas. For the same reason it would be wrong to poison drinking water (a shared resource), or to abandon all the rules of the road (also a shared resource) while driving, it is also wrong to knowingly endanger our collective immunity to disease.

A utilitarian argument for universal vaccination would say herd immunity is a worthwhile and defensible goal because it creates the “greatest good for the greatest number.” Utilitarianism would even tolerate some risk of harm to a few individuals for the benefit of the many. However, we don’t need absolutely everyone to get vaccinated to create and sustain herd immunity. People who cannot safely be vaccinated should receive a medical exemption, period. No one is asking for heroic sacrifice. We just need more people to step up. Unfortunately, the goal of herd immunity keeps slipping away because far too many people are refusing vaccination without a good reason. As we all know, this gives new variants of the virus a continual supply of hosts.

It is remarkable that people were so much more willing to take the risk of trying the experimental polio vaccine in the 1950s – or I should say subjecting their children to trying the polio vaccine – than they are now to take the fully FDA-approved Pfizer vaccine for COVID-19. The science and safety of vaccines has improved significantly since the mid 20th century. Why hasn’t public confidence kept pace? I think the answer to that is complicated. The fear, paranoia, and misinformation surrounding the COVID vaccines have clearly affected people’s judgment, but the reasons for the alienation – from a sense of community and shared humanity – run deep.

As for masks, wearing one has seemed from the beginning of this pandemic like such a small ask. We see old black and white photographs of people wearing cloth masks during the 1918 flu pandemic, going to ballgames, going about their business. We don’t get the sense that these people were angrily protesting masks and shouting, “live free or die.” Unless there is a medical reason why a person cannot safely wear a mask, yes, there is a moral obligation to wear one to reduce the transmission of disease. Notwithstanding the cases of violence that have erupted over the issue of masks, my sense is that most Americans, most of the time, have adapted quite readily to mask wearing. Because that is what humans do – they innovate, adapt, and work together for the good of the community.

TA: Does anyone have a moral obligation to get tested if they are experiencing symptoms?

Harwood: Getting a definitive test result is always a good idea if the illness being tested is transmissible and the test to identify the illness is accurate. A false positive or a false negative doesn’t provide any useful knowledge. But knowing for sure that you have strep throat rather than allergies, for example, is crucial information for getting the right treatment and justifying isolation from others.

Individuals who are experiencing symptoms of COVID – which by now we know better how to recognize – should get tested with the most reliable test (PCR test) because the results (whether positive or negative) provide crucially important information for the good of the local, state, national, and global community. Being sick with COVID is not a solitary event. It is contracted from others and can be passed on to others – family members, fellow students, co-workers, fellow shoppers at the grocery store. People who test positive should notify the people close to them, insofar as they are able to do that work, and notify their employers or schools. We could and should build better systems for contact tracing and notification that would share the responsibility and the labor of notification. I think that would be prudent and fair. But step one is getting tested so that steps can be taken to reduce further transmission of disease.

TA: Does anyone have a moral obligation to tell others if they have been diagnosed with COVID?

Harwood: With a positive COVID test, there is unquestionably an obligation to quarantine. It’s almost unthinkable that someone who knows they are positive for COVID would step onto an airplane, or attend a social gathering, and yet we know there are instances of this happening. People have their reasons for thinking their personal priorities trump public health, but such thinking demonstrates an appalling disregard for others. Indeed, one can easily imagine criminal liability for such behavior. [Editor’s note: here is an example under North Carolina law.]

As for an obligation to tell others of a positive COVID diagnosis, it depends on the nature of the contact and the nature of the relationship. Notifying people with whom you share living space, e.g., family members or roommates, would be obligatory, as would be notifying the guests at a party you threw while unknowingly coming down with COVID. But calling up everyone in the lecture hall where you attended class? Such an obligation would be burdensome, unrealistic, and arguably an erosion of your privacy. Better would be to notify the school and let a team of paid and capable contract tracers promptly identify and notify those individuals who need to know.

TA: What are the ethics of workplaces requiring vaccination?

Harwood: Now that the Pfizer vaccine has received full FDA approval, employers are justified in requiring vaccination of their employees. They are not asking their employees to do something dangerous or take an unnecessary risk. They are not being unduly paternalistic. Requiring vaccination protects everyone in the workplace and it reduces community spread overall, thereby protecting vulnerable people who cannot get vaccinated and all children younger than 12 who are not yet eligible.

TA: In places that are requiring vaccination, there are often religious exemptions. Given your expertise on the relationship between religious traditions and biomedical ethics, what are the theological justifications for these exemptions?

Harwood: It certainly seems that people are straining credulity in what they characterize as a “religious” reason for requesting an exemption from vaccination. Some are turning to religious exemptions as a last resort, when the “nonreligious personal belief” exemption is no longer available. So there is an expediency to this use of the religious exemption that undermines its authenticity in many cases.

One might expect a group like Christian Scientists to refuse vaccination across the board, but this is not the case. Although Christian Scientists normally rely on the power of prayer for healing, rather than modern medicine, they recognize their obligations to public health: “For more than a century, our denomination has counseled respect for public health authorities and conscientious obedience to the laws of the land, including those requiring vaccination. Christian Scientists report suspected communicable disease, obey quarantines, and strive to cooperate with measures considered necessary by public health officials. We see this as a matter of basic Golden Rule ethics and New Testament love.”

By contrast, some white Evangelicals have adopted a problematic understanding of moral purity that compels them to avoid what they perceive to be polluting or contaminating medical procedures. It is not hard to see this fear of contamination among people seeking religious exemptions from vaccination. However, as philosopher Ruth Groenhout has observed, Evangelicals’ obsession with purity puts them, ironically, “into precisely the position of the Pharisees, the only group of people consistently criticized by Jesus for privileging their own moral purity and observance of the finer points of the law over providing assistance to the needy or care for the ill (Matt. 23:1-39. Luke 11: 37-54). The New Testament provides little comfort for religious believers who focus so exclusively on their own moral purity that they are willing to see others suffer for it.”

Groenhout goes on to say that in her reading of the New Testament, Jesus “advocated an ethics of service and assistance to all (Matt. 26:14-39, Luke 22: 24-27, John 13: 1-17), but especially to those seen as one’s enemies (Matt. 5:43-48, Luke 6: 27-36) and to the sick and poor (Matt. 25:31-46).”

So, although people may cite verses from the Bible to explain their desire to refuse the vaccination, and they may claim that their beliefs are “sincerely held,” these things by themselves do not constitute a plausible and coherent theological justification for a vaccine refusal.

  1. Why do those pushing the vaccine ignore the science behind natural immunity? If one has been infected with covid-19, then one does not need a vaccine. They have natural immunities. I listened to a interview from the scientist who pioneered the mechanism for MNRA vaccines. He said you cannot vaccinate you way out of a pandemic. That the vaccinated are actually the reason the virus to mutates. Those that are healthy and not within the high risk groups will eventually be exposed to the virus, it’ll run its course and they will survive 99% of the time. Why do you suppose so many front line health care workers, are refusing to take the vaccine? Because they have been exposed, they understand the science and refuse to put foreign substance into their body unnecessarily.

    1. Unfortunately, the available science on natural immunity is not as comforting as you suggest — for several reasons. The evidence suggests that natural immunity wanes more quickly than vaccine-induced immunity. It is also more variable, with the available evidence suggesting that people who have had a “mild” case of COVID also having a less pronounced immune response. What’s more, the only way to get natural immunity is to become infected with COVID-19, which raises the possibility of death, serious illness, and (in more than a third of cases) the condition known as “long COVID.” There’s a fairly straightforward infographic that explains the differences between natural immunity and vaccine-induced immunity here: https://www.immunology.org/coronavirus/connect-coronavirus-public-engagement-resources/covid-immunity-natural-infection-vaccine

  2. People who refuse to get the vaccine and then proceed to go out into society without regards for the harm they are causing others by being asymptomatic carriers is an action done with forethought and and malice. There can be no claim to “I didn’t know or mean to harm”, given the way Covid has dominated all our lives for the past 18 months. The choice not to vaccinate does not come with the right to harm ( even kill) others.

  3. Attending NCSU, completing your studies, and having the honor of being an alumnus of State were also choices you made. You were required to show proof of vaccination for specific diseases and proof of a negative TB test in order to do so. Unless you are living off the grid and in social isolation, you are a part of the society that our government represents. You submit to many government mandates (traffic laws, airline travel restrictions, food safety requirement, public health directives, etc.) however indirectly they may seem to effect your life, every day you participate in our society.

    You expect more from our society and its government than you are apparently willing to admit.

  4. You just compared my moral obligation to getting a vaccine to poisoning drinking water. 1. Poisoning drinking water is done with malice, forethought and intent to harm. No way is that the same as not taking an action in getting a vaccine.. 2. Driving a car is a privilege in society not a right. You agree to the the rules of the road when you accept a driving license. There are laws and consequences if you break these rules. 3. Yes an employer can require a vaccine as a condition of employment, but I have the right to not work for that company. I did not submit to government or the church to be a part of society. I did not agree to be a part of the herd, follow the herd or be ruled by either. Society can no more force me to get a vaccine, than it can force me to join the church of government. Expected more. Don Efird 1984

  5. I agree with Prof. Harwood’s analysis and am grateful that the Bulletin editors 1) decided to devote space to serious moral reflection on a critical social issue, and 2) reached out to Dr. Harwood to guide our thoughts. Well done!
