Science, Pseudoscience, and the Frontline Practitioner:

The Vaccination/Autism Debate

Erina White

School of Social Work, Simmons College, Boston, Massachusetts, USA

This article demonstrates how misinformation concerning autism and vaccinations was created and

suggests that social workers may be perfectly poised to challenge pseudoscience interpretations.

Utilizing social network theory, this article illustrates how erroneous research, mass media, and public

opinion led to a decreased use of vaccinations in the United States and a seven-fold increase in

measles outbreaks. It traces the dissemination of spurious research results and demonstrates how

information was transmitted via a system of social network nodes and community ties. This article

encourages social workers, as frontline knowledge brokers, to counter misinformation, which may

lead to significant public health consequences.

Keywords: Vaccinations, autism, social work, misinformation, social network theory

It is often difficult to understand how theoretical training in social work fits into real-world practice.

Even when theory explains how a social phenomenon negatively impacts our clients, the role that

frontline social workers play in disseminating accurate information often remains unknown. Thisis particularly evident in the vaccination/autism debate in which the public health consequences

of erroneous knowledge diffusion along social network ties make it increasingly difficult to ignore

the relevance of theory and the importance of social workers as frontline knowledge brokers of

science.In the past 20 years, dishonest researchers, contradictory scientific results, and mass media have

contributed to an vaccination/autism debate. In spite of overwhelming data that indicate that there

is no association between autism and vaccinations (Gerber & Offit, 2009; Institute of Medicine

[IOM], 2004; Taylor et al., 2002), one in four Americans continue to believe that vaccinationscause autism (Gross, 2009). Many parents opt not to vaccinate their children (Gross, 2009; Hall,

2009; Moreno, 2005) and a vaccination fear has created a seven-fold increase in measles outbreaks

in the United States (Begley & Interlandi, 2009).

This article employs a social network framework to examine how media, including television,pop-culture news, talk shows, blogs, and social network Web sites have contributed to a change

in public opinion and a decreased use of vaccinations. First, this article illustrates the background

of scientific evidence on autism and vaccination and how conflicting messages might have ledto a mistrust of science. This the role of the media in the manufacturing and dissemination

of misinformation is highlighted; a social network approach is used to understand how media

reshaped health knowledge and changed public vaccination behavior. Finally, a discussion is

provided on how social workers may be uniquely poised to function as science translationists ina growing climate of media sensationalism and pseudoscience.

BACKGROUND OF AUTISM/VACCINATION EVIDENCE

The autism/vaccination debate began when Wakefield et al. (1998) identified an association

between the measles, mumps, and rubella (MMR) immunization and autism. Other peer-reviewedarticles asserted similar dangers, such as the mercury contained in thimerosal causes neurode-

velopment disorders linked to autism (Geier & Geier, 2003a, 2003b, 2006) and that there is an

association between measles vaccinations and central nervous system autoimmunity in autism(Singh, Lin, Newell, & Nelson, 2002).

Shortly thereafter, several rigorously conducted studies contradicted Wakefield et al.’s (1998)

original findings (Black, Kaye, & Jick, 2002; Madsen et al., 2002; Taylor et al., 2002) and a

meta-analysis “effectively dismissed the notion that vaccines cause autism” (Gerber & Offit, 2009,p. 460). Clear evidence from the Centers for Disease Control and Prevention (CDC) indicated

that the mercury contained in vaccinations is not associated with deficits neuropsychological

functioning (Thompson et al., 2007), and several scholarly works demonstrated that vaccinations

do not weaken the immune system (Black et al., 1991; Offit et al., 2002). Similarly, in a reviewof more than 200 epidemiological and biological studies, IOM released a report revealing that the

committee unanimously “favors rejection of a causal relationship between thimerosal-containing

vaccines and autism” (IOM, 2004).

CONFLICTING EVIDENCE CREATES A MISTRUST OF SCIENCE

Some scholars suggest that the initial conflicting scientific evidence coupled with continued

publication of methodologically unsound studies weakened the credibility of “hard” science in the

autism vaccination debate (Goertzel, 2010; Hall, 2009). The Lancet published Wakefield et al.’s(1998) study in spite of its small sample size, lack of a control group, and hypothetical conclusion.

Later evidence emerged that the primary author, Wakefield, had a conflict of interest, falsified

medical records (Begley & Interlandi, 2009), and engaged in numerous instances of professional

misconduct, including buying blood from boys at his son’s birthday party (Hall, 2009).In spite of the misconduct by Wakefield, and the questionable results of the Wakefield et al.

study example, psychologists such as Seitler (2010) continue to publish anti-vaccination opinions

using spurious research data. In addition, other authors, such as the Geiers (Geier & Geier, 2003a,

2003b, 2006), publish anti-vaccination material in reputable journals despite evidence that indicatesthey have poor research practices and conflicts of interest (Moreno, 2005).

DESCRIPTION OF THE MEDIA ON THE ISSUE

The media has played a particularly important role in disseminating misinformation and sen-sationalizing the vaccination debate. Cameron (2011), a reporter with The Gazette (Montreal),

suggested that the international anti-vaccination delusion is based on “fears and convictions that

were launched by one fake researcher, followed by a decade-long three-level process of editing

and publication going wrong” (p. A19). The media substantiated inaccurate science by publishingerroneous evidence, indulging in celebrity testimony, and balancing credible science with fear-

based anecdotes.

VACCINATION/AUTISM DEBATE AND SOCIAL WORKERS 271

From the onset, media headlines on the vaccination/autism debate have exaggerated scientificevidence and perpetuated fear. The day after the original Wakefield et al. (1998) article was

released in The Lancet, headlines in the UK press falsely stated, “doctors link autism to MMR

vaccine and ban three-in-one jab” (Begley & Interlandi, 2009). In addition many reporters tended to

concentrate on celebrities and public officials rather than science. Journalists broadcasted whetheror not then British Prime Minister Tony Blair had vaccinated his child (Begley & Interlandi, 2009),

and focused on personal stories of U.S. politicians than rather than critical scientific literature of

findings (Moreno, 2005). Long after rigorous scientific evidence clearly rejected a link between

vaccinations and autism, the media continued to cover politicians and celebrities who attackedscience (Begley & Interlandi, 2009; Kennedy, 2005). Even more credible news media, such as

60 Minutes (November 12, 2000) and the New York Times Magazine (Allen, 2002) reported on a

link between autism and vaccinations.

The media also blurred the distinction between scientific evidence and concerned citizensexpressing lay opinions. When Larry King pressed Jenny McCarthy, an American model and

actress, about the link between autism and vaccinations being scientific or statistical she responded,

“Well, I believe that parents’ anecdotal information is science-based information : : : ” (as cited in

Kay, 2010). While King allowed McCarthy to create her own science, Oprah Winfrey applaudedMcCarthy’s “mommy instinct” (Robotham, 2011). The media portrayed Wakefield and McCarthy

as “brave warriors against authority” (Robotham, 2011) and positioned them as crusaders against

hard science.

Theorists have begun to explore how the media creates science (Finn, 2010; Mnookin, 2011;Robotham, 2011). For example, in a content analysis of the professional medical literature sur-

rounding autism and vaccinations, Finn (2010) revealed a concern about the emerging phenomena

of an era of publicly made science created in the digital environment by self-appointed experts.Similarly, journalism professor Philip Chubb discussed the harmful effects of media tendency

to “balance” various perspectives when the balance is between credible evidence and opinions

motivated by extreme ideology (Robotham, 2011). The media, which is traditionally viewed as a

source of quick and accurate information, creates its own science when it focuses on emotional,anecdotal and sensational stories—as it did in the autism/vaccination debate—rather than scientific

fact.

SOCIAL NETWORK APPROACH AND A NEW ‘‘EXPERT’’

VACCINATION KNOWLEDGE

The social network approach explains how a series of confusing messages and conflicting scientificstudies were translated into an anti-vaccination campaign by a wealthy, well-educated group

of parents (Gross, 2009; Mnookin, 2011), often referred to as the “web-surfing soccer mom

population” (Kay, 2010) and “intensive mothers” (Robotham, 2011). Ultimately this knowledge

transformation contributed to higher numbers of unvaccinated children and an increase in vaccine-preventable deaths (Begley & Interlandi, 2009; Gross, 2009).

The social network approach is defined as “neither a method nor a metaphor, but a funda-

mental intellectual tool for the study of social structures” (Wellman & Berkowitz, 1988, p. 4).

This theoretical approach asserts that social structures are networks, comprised of nodes (i.e.,individuals, groups, households, and nation-states) and ties (i.e., interconnections that represent

flows of resources, friendships, and transfers of information between nodes). This theory has been

used to understand various social structures and systems such as London’s advertising industry

(Mould & Joel, 2009), online support groups (Muncer, Loader, Burrows, Pleace, & Nettleton,2000), and technology groups in Germany (Kratke, 2011). Some studies have even used this

theoretical approach to examine how informal social pressures impact subjective opinions (Burt,

1987). For example, in a study examining the diffusion of medical information among physicians,Burt found that doctors in similar environments tended to develop similar responses, attitudes,

and behaviors.

In the vaccination/autism debate, social network analysis helps to explain how entire vaccine-

resistant communities have emerged in Colorado, Washington, Oregon, and California (Gross,2009). Physical proximity of nodes and the community ties that bind them create a community

aversion to vaccinations. For example, in a small town in Oregon, only 70% of parents vaccinate

their children compared to 95% of Oregon state residents (Gross, 2009).

Social network analysis also informs how technology allows like-minded nodes to form acrosssimilarly minded ties. The advent of computer-supported technology has allowed social networks

and communities to occur virtually (Wellman et al., 1996). Pockets of similar types of people

transmit and diffuse ideas across non-physical lines leading to an explosion of information, whether

accurate or not. For example, one woman reports perusing Web sites, canvassing friends, pollingher followers on Twitter, and quizzing her doctor to determine whether or not to vaccinate her child

(“A Shot in the Dark,” 2010). Such individuals make decisions based on both regional proximity

and a networking of similar beliefs, which may expand to include blog sites, organizations, states,

and continents. Parents who wonder about vaccines “share the fruits of their online investigationsand doubts with moms groups, listservs, chat rooms, and friends” (Gross, 2009, p. 6).

Social network theory also explains how an overflow of information coupled with peer pressure

contributes to the formation of “the intensive mother” (Robotham, 2011); and how, in turn,

collaborative action of the intensive mother perpetuates anti-vaccine sentiments. “Intensive moth-ers” reevaluate traditional parenting norms and often form decisions based on social support

information and online media sites:

Upper middle-class mothers are starting to question immunisation more than they would have done,

as part of a suite of things they want to do for their child-things like baby gym. You want to show

you’re doing a good job of mothering and not just accepting the status quo. (Robotham, 2011)

A proliferation of information, the media tendency to present “balanced” information rather

than accurate scientific evidence (Mnookin, 2011), and an increased social network of “intensive

mother” peer pressure contributes to the confusion about the right vaccination policy.

The social network approach demonstrates how conflicting scientific reports, media, and infor-mation technology produced a new vaccination knowledge. As erroneous vaccination information

is passed along social network Web sites and among nodes and ties of “people like me,” mistrust

in rational scientific knowledge is expanded. The expert role of impartial academic is replaced by a

social-media-network expert-knowledge broker created by “people like me.” Unfortunately unlikechoosing baby gym, neglecting to vaccinate children has far reaching and deadly consequences.

A CALL TO SOCIAL WORK

Social workers are poised to counter social networks gone awry. As direct care providers and

front line experts, they may hold the key to preventing the dissemination of misinformation

among clients. In medical settings social workers have the unique opportunity to translate newscience into practical application. As direct care clinical providers, social workers often have

access to “real science” and are aware of whether or not clients are ascribing to and following

pseudoscience practices. A wide array of professionally-targeted options may be used to correct

misinformation: medical pamphlets in hospital settings, scientifically informed leaflets in direct-care outpatient offices, information sessions in school social work settings, and verbal correction

of inaccurate scientific information among clients in psychotherapy.

VACCINATION/AUTISM DEBATE AND SOCIAL WORKERS 273

Historically, unlike the media’s bias to present “balanced” information, social work has beencharged with providing correct, current, and life-saving information. Social workers do no harm

and attempt to prevent future harm. With the distinct perspective of viewing clients in their environ-

mental context, social workers are often privy to insider information about client practices, trends,

social networks, and adoption of erroneous information. As a profession, social work is singularlypositioned to utilize this first-hand knowledge to challenge pseudoscience interpretations. Given

the global public health concern of increased measles outbreaks and decreased vaccinations, this

article serves as a call to social workers, as multidisciplinary professionals providing front-line

care, to read the science, become educated experts, watch for the dissemination of erroneousinformation among social network ties, and present the accurate evidence.
