The social impacts of COVID-19 on the global population have been well known since its declaration as a public health emergency. Each nation has been forced to negotiate its own priorities and plan accordingly, often creating a patchwork of different plans in different areas. While the citizens of each country have had varying degrees of difficulty adjusting to the new international situation, refugees have been ignored, sidelined, and immobilized.

EBOLA VACCINE DEVELOPMENT PROVOKES STEM CELL CONTROVERSY

Stem Cell Research, Attempting to Cure Blindness

The Ebola scare currently sweeping across the United States is far from unfounded; the outbreak of the disease in West Africa is acknowledged as the most widespread to date, having now killed over 5,000 people. It recently threatened to spread across Mali, where it has already claimed the life of a nurse who had been treating an infected individual. Sierra Leone has also been hit particularly hard by the disease, as caregivers continue to test positive for Ebola. The remaining staff are understandably unnerved, and some have gone on strike in response to a lack of monetary compensation for the risky nature of their work.

American nurses and other volunteers appear to echo this sentiment, criticizing the inadequate protection provided to caregivers combating the illness overseas. Though the United States was recently declared free of Ebola, it had been viewed as a very real concern only a short time ago. The first case in the states occurred in September, where a man in Texas was diagnosed with Ebola and died eight days later; two of the nurses tasked with treating him were also infected, but survived. The most recent case manifested in the Oct. 23 diagnosis of a doctor who had been combating Ebola in Guinea, and has since been discharged.

Though the eradication of the disease in the United States does mark a celebratory milestone, the Ebola scare has certainly left its mark as steps have been taken to develop a functioning vaccine. A vaccine developed by GlaxoSmithKline (GSK), as well as by the US National Institutes of Health, is expected to commence with human trials in West Africa as early as next month. These apparent medical strides in the fight against Ebola, however, have garnered a less than enthusiastic response among ardent pro-life groups. On group in particular, Children of God for Life, is opposing the vaccine on the grounds that it was developed through stem cell research. Working with stem cells often provides doctors with important insights regarding organismal development, and the practice has proven invaluable in its potential to fight disease. But there is a somewhat questionable means to that end – stem cells are primarily obtained through the destruction of human embryos. A member of Children of God for Life, Debi Vinnedge, has gone so far as to criticize the Obama administration as being “completely irresponsible” for approving the development of these vaccines, claiming that they cannot be “[used] in good conscience”. The group is currently pushing for “morally acceptable alternatives”.

Controversy surrounding stem cell research is not a new phenomenon – the two have coexisted since the inception of the latter. It is primarily the methods through which doctors and researchers obtain stem cells that occasionally incite public backlash, more so than the practice of working with these cells itself. One common way of acquiring stem cells is though the deliberate creation, and invariably subsequent destruction, of human embryos. Stem cells can also be harvested from “aborted fetal cell lines,” which is the practice that the Children of God for Life alleges is being employed in the development of Ebola vaccines. The potential benefits surrounding the use of embryonic stem cells in medical research are staggering. Observing stem cells allows an enriched understanding of how a disease first occurs, as well as the effects it has on the body. Stem cells are undifferentiated, unspecialized cells with the extraordinary capacity to later develop into different types of cells. They are highly regenerative, and have the potential to be manually developed into a particular variety of cell – the qualities most responsible for their appeal in drug and medicinal testing.

As complicated as it is to denounce the benefits derived from stem cell research, it is equally complicated to ignore the ethical issues that also concern it. Many of these problems find some overlap with those revolving around the concept of abortion; chief among said issues is the matter of human life, what defines it, and where it begins. There are some religions – namely Catholicism – that maintain that human life begins at fertilization; there also exist other parties that, speaking from what they refer to as a more scientific point of view, question this idea and propose that human life may begin farther along chronologically. Whatever one chooses to accept as true, it is probably with some measure of difficulty that they reconcile themselves to the use of human embryonic stem cells in such a manner, versus that of another animal species.

The central issue at hand concerning stem cell research involves the matter of their acquisition: the Children of God for Life group, is demonstratively opposing the development of the Ebola vaccine on the grounds that it is being tested on stem cells derived from aborted fetuses. The concept of using induced pluripotent stem cells (iPSCs), versus stem cells obtained from human fetuses, has the potential to eliminate such controversy. iPSCs are defined as adult cells, often taken from the blood or skin, that are then programmed to return to an embryonic state closely mirroring that of stem cells. In this regard, the iPSCs can act as a benignly obtained substitute for stem cells that ultimately serves the same purpose. While iPSCs have tremendous potential, as a newer scientific breakthrough further research is required before they can reach quite the same level of practical usefulness as traditional embryonic stem cells.

If the progress in the production of preventative vaccines as substantial as it promises to be, it would arguably be unethical not to pursue their development to the fullest extent. The current Ebola outbreak has afflicted 14,000 and killed over 5,000. The method in which the potential vaccines are tested might be morally troubling, but stem cell research is not a new concept. Stem cell research is being used in other studies at this very moment, in the search for cures to ailments such as Alzheimer’s among many others. It is the prevalent fear that the rigorous spread of Ebola has incited that has given a new face to an old controversy. If there are indeed economically feasible ethical alternatives to such testing, it is worth noting that they might merit trial in the future. The use of iPSCs, for example, shows great promise in the future of drug and medicinal testing. But as matters stand right now, pursuing a vaccine that combats an obviously very pervasive illness should be the world’s first priority. Tragic as it is, there are nearly always casualties where global advancement is concerned.

EBOLA AND AIDS: A COMPARISON OF CDC AND PUBLIC REACTIONS

Ebola Virus

By Alexandra Reich

As the Ebola epidemic continues in West Africa, Ebola-related anxiety spreads across the United States. While it is natural to empathize with societies dealing with the epidemic, is the paranoia of the average American citizen over contracting the disease valid? So far, there have been only five confirmed Ebola cases in the United States. Although Ebola is deadly, it is not very contagious. Ebola is contracted through coming into physical contact with an infected person’s skin, bodily fluids, or contaminated surfaces. This means that a person is unlikely to contract the disease just by being in the vicinity of an affected individual; direct contact must be made. Ebola shares many early symptoms with the much more common and less dangerous flu, and symptoms can take up to 21 days to appear. It is also noted that a person with no symptoms is not contagious, even if they are carrying the disease. With the sanitary and educational resources that the United States possesses, a severe Ebola outbreak in the United States is highly unlikely.

Nevertheless, American citizens responded to the spread of the disease in West Africa and hints of the disease in the U.S. with disproportionately heightened levels of anxiety, especially after a commercial jet passenger, a healthcare worker, was reported to have contracted Ebola from her Ebola-infected patient. Although she had called the Center for Disease Control and Prevention (CDC) before her flight and reported a fever, the CDC did not prohibit her from flying. As a result, the plane’s passengers were at a slight risk of contracting a disease that is spread through direct contact.

People who suspected they could possibly come into contact with a person who had been on that flight, even if highly unlikely, began to take extreme precautions against exposing themselves to Ebola. Multiple schools with potential connections to the flight carrying the Ebola-infected health care professional were shut down for cleaning. Even a local San Diego community college student recently misinterpreted her flu symptoms as Ebola symptoms, and her class was quarantined as a result. She was later confirmed not to have contracted the disease. Are these measures unnecessary and invoking of public fear, or are these safety precautions necessary in the face of insufficient governmental control of public health? The news of the Ebola-infected person on the plane was a very terrifying, and very tangible, situation. For many U.S. residents, sitting in close quarters with complete strangers is a daily occurrence. Also, even though the CDC claims the risk is low that anyone on the flight contracted Ebola from the nurse, they did acknowledge the possibility, and they are now seeking out the remainder of the plane’s passengers for interview as a precautionary measure, adding to public anxiety.

While these measures of shutting down schools may seem like a drastic and unnecessary precaution, the CDC has proven its incompetence in the past with the handling of the initial AIDS epidemic in the 1980s. In the early years of the AIDS epidemic, the CDC was aware that the disease mostly affected homosexual men and intravenous drug users, and it could be passed from mother to unborn child [1]. These trends suggested, even before the HIV virus was scientifically dissected, that the reoccurring pattern of disease could be transferred by the use of shared needles or by bodily fluids during sexual intercourse. However, the CDC failed to put educational programs in place to help prevent the spread of the disease at this time. Therefore the spread of the AIDS virus in the U.S. was due to the government’s neglect of the situation. Looking at the research and initial treatment of AIDS illustrates the incompetency present in the United States’ public health system. The National Cancer Institute waited nearly two years before organizing research team [2]. It is logical that citizens can’t trust the United States system of public health because of its past failures.

However, the treatments of AIDS are also largely due to societal neglect, in addition to governmental neglect. The majority of the HIV-positive community in the U.S. consists of homosexual men and intravenous drug users (IDUs), many of whom were also racial minorities [3]. Homophobia and racism very likely have a hand in preventing adequate public health and medical care from being available to these populations. A prejudice existed against AIDS as a “self-inflicted” disease that used up medical resources [4].

The public’s response to AIDS was a lack of toleration, as opposed to the hyper-cautious approach to Ebola. The difference in response is mainly related to the transmission mechanism of the disease. While HIV, often transmitted sexually or by intravenous drug use, could be blamed on the individual, an Ebola patient could contracted the disease, in the public’s eye, by being in the wrong place at the wrong time. This is why the closing of schools is passed off as a preventative measure and not excessively cautious. The similarities between AIDS and Ebola lie in the failure of governmental public health institutions. To clarify, the CDC handling of AIDS was a complete and total failure, while the CDC’s handing of Ebola, largely successful in containing the disease itself, has been insufficient to maintain a sense of public safety and security. In the face of high levels of public anxiety, the CDC needs to enhance education about Ebola, but more importantly, take the necessary measures to prevent slip-ups such as the Ebola-infected nurse flying on a commercial flight. The nurse’s presence on the plane did not result in the transmission of Ebola, but it did cause the escalation of public panic.
