Yeah, that makes sense.

And do you know kind of what conversations they're having?

I was wondering, are they going around and kind of shaming parents for being like lousy parents because they're, I don't know, not vaccinating their kids?

I know there's this whole thing of people policing like other parents' behavior and things like that.

Or is it more like they're reminding people of this fun vaccination event that they can go to?

What's the conversation I should picture in my head?

Yeah.

Okay.

So just to have a picture in the head of the magnitude of the benefit, you're saying it increases vaccination rates by 10 percentage points, and that's about 27%.

So huge magnitude.

How large is the SMS reminder effect again, separately?

Three and seven percent.

Okay.

So I'm guessing the SMS reminders are a bunch cheaper because you're just sending texts.

And I guess they're probably easier to scale as well because you just have to get a bunch of phone numbers and then stick them in some piece of software that sends out text messages.

On the other hand, it seems like the ambassadors have a larger effect size, maybe a more robust result in the RCT.

How are you going to trade off this like easiness of scalability and low cost?

In the original version, people would go to the village.

Exactly.

Maybe I've got the wrong picture in my head here.
