Causes of COVID Vaccine Hesitancy

By Jasper L. Tran

Vaccinated individuals — like Tolstoy’s happy families — are all alike; each unvaccinated individual is hesitant for her own reason.

Prior research conducted in developed countries reveals five main individual-level determinants of pre-COVID vaccine hesitancy (commonly referred to as the 5 C model drivers of vaccine hesitancy): (1) Confidence (trust in vaccine’s effectiveness and safety, vaccine administrators and their motives); (2) Complacency (perceiving infection risks as low and vaccination as unnecessary); (3) Convenience / Constraints (structural or psychological barriers to converting vaccination intentions into vaccine uptake); (4) Risk Calculation (perceiving higher risks related to vaccination than the infection itself); and (5) Collective Responsibility (willingness to vaccinate to protect others through herd immunity).

COVID-19 vaccines see these five hesitancy determinants again, only further exacerbated by waves of misinformation promulgated on social media, including through “bot” accounts, that prey on the concerns and insecurities of an already vulnerable public.

On the one hand, irrational and unreasonable conspiracy theories about COVID-19 and its vaccine abound among the anti-vaxxers — a subgroup of science deniers. These conspiracy theories include:

Preventing Misuse of COVID-19 Vaccine Medical Exemptions

By Ross D. Silverman and Gabriel T. Bosslet

As COVID-19 vaccination mandates become increasingly common, we can expect exemption requests (and misuse) to become increasingly widespread, too.

Most entities requiring vaccination mandates or proof of vaccination upon entry may offer limited grounds upon which an individual may request an exemption, usually based upon religious beliefs or medical reasons. Recent history with childhood immunization programs shows less rigorously-structured and -enforced vaccination exemption policies are vulnerable to increased usage, relative to narrower or more stringently-monitored programs. That history also shows there is a possibility some health care licensees may be willing to support individuals seeking to circumvent COVID-19-related requirements through offering questionable medical exemptions.

Entities imposing COVID-19 vaccination mandates, and state health care licensure boards, can take several simple but significant steps to counter misuse of medical exemptions and better protect communities from COVID-19. These safeguards also can decrease the temptation for licensed health professionals to recklessly undermine critical, lawful, evidence-driven public health efforts.

What Makes Social Movements ‘Healthy’?

By Wendy E. Parmet

Social movements can play an important role in promoting population health and reducing health disparities. Yet, their impact need not be salutatory, as is evident by the worrying success that the anti-vaccination movement has had in stoking fears about COVID-19 vaccines.

So, what makes a health-related social movement “healthy?” We need far more research about the complex dynamics and interactions between social movements and health, but the experience of a few health-related social movements offers some clues.

Religious Exemptions to Vaccines and the Anti-Vax Movement

By Dorit Rubinstein Reiss

Two major problems with granting religious exemptions to vaccine mandates are that they are very hard to police, and that they are routinely gamed.

Religious freedom is a core value in the United States. This makes policing religious exemptions to vaccination hard – and rightly so. The government policing people’s religion raises a number of thorny issues.

The problem is that the same people who eagerly promote anti-vaccine misinformation are just as eager to misuse religion to avoid vaccinating, and have no hesitation or compunction about coaching others to do the same. And without policing, it is easy for those misled by anti-vaccine misinformation to use the religious exemption.

COVID-19 Vaccine Misinformation and the Anti-Vaccine Movement

By Dorit Rubinstein Reiss

The anti-vaccine movement is aggressively working to promote misinformation about COVID-19 vaccines, up to and including promoting fake claims of deaths from vaccines. We need to be aware of its efforts, and be prepared to respond.

It’s worth emphasizing that this blog post is focused on the anti-vaccine movement, not people with concerns about vaccines (the “vaccine hesitant”).

In relation to COVID-19, anti-vaccine activists have aggressively promoted misinformation from the start of the pandemic.

In March 2020, anti-vaccine activists incorrectly alleged – by misrepresenting a study – that flu vaccines increase COVID-19 risks. In June, anti-vaccine activist Del Bigtree described COVID-19 as a “cold,” blamed those who died for their own deaths, and called on his followers to “catch that cold.”

And from the beginning, anti-vaccine activists were committed to the ideas that COVID-19 vaccines would not work, would be dangerous, and would be promoted by a nefarious global conspiracy. They continue to spread these allegations, for example, using the fact that there are liability protections for COVID-19 vaccines to imply the vaccines are dangerous. Liability protections for COVID-19 vaccine manufacturers are real; but they are not evidence that the vaccines are unsafe.

This post will focus on one type of misinformation: alleged deaths from COVID-19 vaccines.

Past Anti-Vax Campaign Provides Insights for Current COVID-19 Debates

By Dorit Rubinstein Reiss

A new book on a prominent misinformation campaign targeting the measles, mumps, and rubella (MMR) vaccine has profound insights into current vaccine debates, such as those emerging around a potential COVID-19 immunization.

The Doctor Who Fooled the World: Science, Deception, and the War on Vaccines,” by Brian Deer, exposes the elaborate fraud perpetrated by Andrew Wakefield, the former British gastroenterologist who, in the late 1990s, created a scare about MMR vaccine by suggesting it caused autism.

Brian Deer is the journalist who, through several years of dogged investigation, exposed Wakefield’s hidden conflicts of interests and misrepresentations, showing that the small study used to create the scare was not just deeply flawed – as was apparent on its face – but an elaborate fraud.

Unfortunately, Wakefield and his misrepresentations are still with us, and are still putting children at risk all around the world. This makes Deer’s book – which teaches us how Wakefield tricked the world, and the lasting impact of his fraud – timely and important.

Running healthcare, research and public trust up the flag pole

While I was aghast earlier this week that the White House struggled over whether to fly the flag at half-mast or full for the death of John McCain, and relieved that it was still the American flag, I distracted myself from the drama in Washington with other news:

Item: In Europe, there were 5,000 cases of the measles in all of 2016, 24,000 in 2017, and already 41,000 halfway through 2018, including 37 deaths, according to the World Health Organization. Globally, measles remains a leading cause of death among young children even though a safe and cost-effective vaccine is available.

Item: In the bizarre case of a convicted murdered claiming his victim wouldn’t have died had he stayed on life support, the Georgia Supreme Court rejected that argument because the patient “was basically brain dead.” [PDF]

Item: Twenty-five years later, gene therapy finally got a common-sense definition: “the intentional, expected permanent, and specific alteration of the DNA sequence of the cellular genome, for a clinical purpose.”

Bioethicists, policymakers, and clinicians tend not to lump brain death, gene therapy and the anti-vaccine movement together. And why should they? Though fate management is central to each, they are perplexing enough to the public (i.e. me) when considered separately.
