Aversion to vaccines is still putting lives of children at risk

“As an infectious disease specialist, there is nothing sadder than standing at the bedside of a parent in an ICU with a child who’s got a vaccine-preventable disease who is dying.”

“As an infectious disease specialist, there is nothing sadder than standing at the bedside of a parent in an ICU with a child who’s got a vaccine-preventable disease who is dying.”

That’s what Dr. Noni MacDonald, professor of pediatrics at Dalhousie University, told us at a recent Senate meeting on vaccine hesitancy.

No child should die a preventable death. But it’s happening today.

Measles outbreaks, for example, are on the rise globally, and in Canada, despite the availability of a safe and effective vaccine.

According the World Health Organization, more than 110,000 deaths were attributed to measles in 2017 alone. Most of the deaths were of young children.

Canada has significant room for improvement.

Even though the vast majority of Canadian parents vaccinate their kids, we still have one of the lowest vaccination rates in the developed world. Nearly one-tenth of children are not vaccinated and remain vulnerable to a host of potentially fatal, vaccine-preventable diseases.

According to a recent study, one-third of Canadians expressed vaccine hesitancy – a reluctance or refusal to vaccinate despite the availability of vaccines. What’s going on?

For starters, as Senator Marie-Fancoise Megie put it, we are fighting a “generational amnesia,” where those who have benefitted from the health that vaccines afford have never seen first hand the destruction that preventable illnesses like measles or polio can cause.

MacDonald summarized vaccine hesitancy as a combination of “complacency, convenience and confidence.”

Complacency because often other things have more prominence for busy parents than vaccines. Convenience because we make immunization too difficult, and confidence because the public has declining faith in institutions, governments and care providers.

Then there’s rampant online misinformation. Dr. Timothy Caulfield, professor in the faculty of law and the school of public health at the University of Alberta, refers to the “mere exposure effect” of social media.

“Just being exposed to nonsense … creates a perception of credibility.”

Science literacy is critical to combat fake news and the polarized discourse of social media, he said.

We need to work with educators to teach critical thinking skills and start young. We also need to address misinformation on platforms like YouTube, Twitter and Facebook.

Dr. Theresa Tam, chief public health officer of Canada, said public health needs to get better at more targeted and tailored interventions to engage specific populations.

“We also need to do a better job of understanding the techniques used to divide and undermine trust in vaccines on social media. Public health needs to harness narratives, behavioural insights and social media influencers to counter false information.

“Address emotions and not just the facts,” she stressed.

Tam also suggested that discussion of vaccination could start earlier when a woman is pregnant and has the opportunity for longer clinical visits.

Andre Picard, public health columnist and author, told the Senate panel that instead of demonizing or punishing the vaccine-hesitant, we should “endeavour to persuade, not prosecute,” even though that’s more difficult.

And we should “counter falsehoods at every opportunity.”

He described the “travesty of public policy” because Canada lacks a single vaccination schedule across provinces and territories, and we don’t even have comprehensive vaccination records.

Picard jokingly suggested that we should “lock all the health ministers in a room and don’t let them come out until there’s one vaccine schedule.” Not a bad idea.

Dr. Anna Banerji, faculty lead of Indigenous and refugee health at the University of Toronto, put forward the idea of mandatory immunizations “framed in the context of social responsibility.”

She also emphasized the need for a specific immunization strategy for Inuit children, who have the highest rates of the deadly respiratory syncytial virus in the world.

One thing is clear: It’s time Canada had a national vaccine framework, including a comprehensive national immunization record-keeping system, harmonized vaccine schedule and delivery, in partnership with the provinces; along with a robust public education campaign.

We need to make it easier for parents to vaccinate their children. It’s time we were all vaccine champions.
