How a vaccine advocate turns down the temperature in discussions around hesitancy

Karen Ernst is the director of Voices for Vaccines, a national organization focused on increasing vaccination rates by providing accurate information to families. The organization is part of the Task Force for Global Health in Atlanta.

Ernst, who lives in Minnesota but often travels to Atlanta, is a former English teacher who became a public health leader focused on 鈥渂ringing people to this place of calm and good information, and helping to protect as many families and communities as possible.鈥 Ernst was featured in the documentary 鈥,鈥 which aired on PBS and was executive produced by Neil deGrasse Tyson.

In Georgia, and nationally, childhood vaccination rates are decreasing, according to recently released by the Centers for Disease Control and Prevention. Georgia has reported six measles cases in unvaccinated people this year. Some is driven by misinformation on research . Vaccines are safe and help save lives, and .

Turning down the temperature on heated conversations on vaccines is part of Ernst鈥檚 approach, and her own questions and anxieties around vaccines when she was a new parent inform her empathetic approach to those conversations.

highlights some of Ernst鈥檚 thoughts about improving communication around vaccines.

How has the dialogue around vaccines changed since you started with Voices for Vaccines in 2012?

鈥淲hat we鈥檙e seeing right now is people really feeling less engaged in their communities in general. This is systemic beyond vaccines. I call it the age of disengagement, people really disengaged themselves from each other. They鈥檙e not as involved in their communities, they don鈥檛 know their neighbors, they don鈥檛 trust their public servants, they don鈥檛 trust scientists who seem very far away. And all of this disengagement has made it a lot more difficult to empower people with information and to get people to trust that vaccines are going to do something good for their family.

鈥淚鈥檝e seen people cornering themselves into their own sphere and have trouble feeling trust. And trust is really engagement, that they are involved in their communities, that they鈥檙e involved with their neighbors, that they have a stake in people鈥檚 lives, that they have a stake in, and a say in, what the government is doing, and what their local public health officials are doing, and what science is happening. That鈥檚 the biggest change I鈥檝e seen. And as I said, it makes it more difficult to engage people, even to even start those conversations. It鈥檚 gotten trickier.鈥

What is the role of social media in the conversation around vaccines?

鈥淲hen I started in 2012, I was already alarmed about social media, and I used to describe those days as the wild west, because you could literally say anything on social media. There were no guardrails. We鈥檝e taken the guardrails away again. Certainly, social media does two things: It amplifies rumors, it amplifies scary stories that are hard to verify, but it also has what I call a pufferfish effect. It makes vaccine hesitancy seem a lot more common than it is. It makes ideas about vaccines seem more prevalent than they are, because it鈥檚 easier to find someone who will think the same thing as you.

鈥淚f we had some guardrails, if we had better engagement in the physical world of our communities, social media wouldn鈥檛 be as much of a factor in driving false information about vaccines.

鈥淚t鈥檚 easy to blame social media, but the problem is us. We鈥檙e the problem because we鈥檙e not engaged with each other.鈥

What are some of the top concerns people have about vaccines?

鈥淭he top one is still concerns that vaccines cause autism. People hear that so much, even with the context of we鈥檝e debunked this, they still hear it. And when they hear it, they think, if there鈥檚 smoke, maybe there鈥檚 fire here. But they don鈥檛 realize that it鈥檚 just like a smoke machine. We try to center autistic voices, but also make sure that people understand that we know a lot more about autism than we used to. We can pinpoint that autism happens before a baby is born.

鈥淎nother is this idea of why do we have all of these vaccines, or how did they even make this schedule? It feels mysterious to people how the schedule is made.

鈥淚t is scary to bring your baby in to get a vaccine, and they鈥檙e like, 鈥楬ey, look at this. We鈥檝e got four needles. Isn鈥檛 this fun?鈥

鈥淚 remember the first time my baby got a vaccine in 2003. I legitimately cried because I was like, this is hurting him. This is hard. It鈥檚 hard to vaccinate your baby. I don鈥檛 know what these diseases are. Why are there so many? Does my baby really need all these vaccines now? It still has not been well explained to parents. There could be a lot more education around these diseases and what exactly a vaccine does.

鈥淭he last one is what鈥檚 in a vaccine? What is a vaccine made of? How do they make vaccines? It鈥檚 like hearing ingredients鈥 names, and they sound scary. When you hear chemical names associated with something that you鈥檙e going to be putting in your new baby, it鈥檚 very scary.

鈥淭hese are all answerable questions. These are all answers that we can provide parents and we should.鈥

How can public health professionals help people understand the value of vaccines?

鈥淚f you鈥檙e a person in public health, you are incredibly powerful in the community that you form around yourself. You should engage people, you should help them understand who you are, what motivates you, why this is important to the work that you鈥檙e doing, and invite them to ask questions, listen to their concerns with empathy, and trust them to understand the science if you explain it in plain English.

鈥淭hat might sound too simple, like, 鈥極h, you just want me to talk to people I know,鈥 but that鈥檚 really where we start. The other part of that is when we talk to people we know, we give them the full power of information, then they can talk to the people that they know. That鈥檚 really the best way to do it. This is where social media can be good for us.

鈥淚t鈥檚 really easy not only to be judgmental, but to be really annoyed with people. Like, 鈥楢re you kidding? I just spent eight hours today doing this intense, incredibly difficult work. I鈥檓 trying to preserve people鈥檚 health, and you鈥檙e coming at me with this, what?鈥

鈥淥ne of the things we really need to do is take our internal temperature on it. 鈥極kay, I鈥檓 annoyed right now.鈥 That鈥檚 okay, just put that little annoyance in your pocket, and come out with your best self. I always say turn annoyance into curiosity: 鈥楬ey, tell me more about what this concern is, or why you鈥檙e asking me this question? Where are you hearing this from?鈥 Turn it into a conversation instead of a lecture.鈥

Is access also a challenge, in getting vaccines to people?

鈥淭here are definitely access problems. I was just in Arkansas, and there are a few counties in Arkansas where the only place you can get your free Vaccines for Children vaccines is at the local health department. You can imagine being like, 鈥榃ell, gotta take two hours out of my life to get my kid vaccinated, or I鈥檓 going to sign this form鈥 [for a religious exemption].

鈥淚f the vaccine was just right there, you would probably just get vaccinated. Even with people who report it as vaccine hesitancy, if you talk to them a little bit, and you have the vaccine available right there, the chances that they鈥檙e going to get vaccinated are better. Sometimes it鈥檚 a timing issue, taking time off of work, not being able to take time off of work during the scheduled hours, thinking I don鈥檛 have time to have a cranky baby for a day. All of these things are part of the tapestry of it, and we always have to be concerned about access.鈥
