Truth decay: Anti-vaccinationBreaking down the anti-vaccine echo chamber

In these days of Facebook and Twitter, it is easy enough to block out the opinions of those you disagree with, and only associate with people whose voices reinforce your own opinions. These echo chambers have real-world implications; currently, the U.S. is in the midst of its largest measles outbreak in decades. That’s why it’s important to find ways to communicate across the vaccination divide.

The rhetoric around vaccination is generally black and white: vaccines are good or vaccines are bad. In these days of Facebook and Twitter, it is easy enough to block out the opinions of those you disagree with, and only associate with people whose voices reinforce your own opinions. These echo chambers have real-world implications; currently, the U.S. is in the midst of its largest measles outbreak in decades. That’s why it’s important to find ways to communicate across the divide.

While the overwhelming majority of the scientific and medical communities (including the authors of this article) agree that vaccines are extremely safe and effective, and that the benefits far outweigh the risks, it is important to note that there have been, on rare occasions, events where certain vaccines have been recalled, and there are very rare occasions when anaphylactic events can occur after vaccination. Failing to admit that these events can occur fuels the anti-vaccination community further in their dangerous rhetoric and pushes them deeper into the echo chambers that exacerbate vaccine denialism. It is important for vaccine advocates to stop completely discounting these fears as impossible and to reframe their argument in a way that acknowledges the fears but underscores the importance, efficacy, and safety of vaccination on the whole, despite the risks.

Many who are on the fence about vaccination are worried about the potential consequences of vaccines; they’ve heard stories about children having severe immunologic reactions or dangerously high fevers after their shots; they’re enticed by anecdotes about children who were vaccinated one day and severely impaired the next. Most of these stories come from a misunderstanding of the common scientific axiom, “correlation does not equal causation,” and carry little to no weight in arguments against vaccinating. Many of the stories are also lies fabricated by the most vocal vaccine deniers and profiteers seeking to further their own dangerous agendas.

But every once in a while, a story will carry some legitimacy, and it does vaccine advocates no good to dismiss them as impossible. Instead of outright dismissing the claims, it would benefit the pro-vaccine community to acknowledge that sometimes, albeit rarely, mistakes occur, and to focus on what the scientific community does to ensure
