Oh I swayed when my son was five (he is ten now)
I was anti vax up till then.
And then there was a measles outbreak not nearly enough away far from where I live, and my fear found it had a competitive situation going on.
Anti vax lost.
What makes this video interesting to me is that I know how my anti vax stance was formed, what influenced it and just how much it had in common with the bulk of my anti vaxing peers.
Yes, I think this video would have crept under our defenses to some degree and made our already non militant anti vax state have a bit of a wobble.
I think it would have softened me up at least for being more open to listening to the skeptic offerings on the subject.
I wouldn't be at all surprised if ZDoggMD was well aware of that potential when he came up with the project. I think he has probably taken a good look at the internal creation of a mainstream anti vax stance on an individual level, and worked out the best route to seek the chinks in it.
I repeat what I said before, I don't think it will have any impact on the people with a firmly fixed, if not militant, position on the issue. I doubt much would.
The thing is, IME the militant tend to be in the minority, which is why they are probably not much of a priority when it comes to designing pro vax campaigns. Makes sense that he would tailor the mode of the message to target the bulk in the middle ground, rather than the extreme fringe.
My position is not fixed, in the sense that if new accurate evidence, from reliable sources, backed by credible studies were to point to little benefit and significant risk associated with vaccines, then I would stop using them.
