I think that now that herd immunity is truly in danger adult boosters will be more promoted.
For example, I had most of my kids in my mid-20s. This was during a pretty big heyday of no vax but most people didn't seem to care. I was never offered a booster or anything like that while pregnant or pospartum. They didn't even ask about my vax status.
For surprise #4 last year jesus christ I must have been asked about my boosters like every visit. And I've been asked a few times since even for non child related medical visits. Even though I'd already had a Tdap a couple of years prior, they still wanted me to have another one plus an additional MMR postpartum. I belong to an HMO though, after two decades of shitty catastrophic care only coverage so I don't know that the message gets out through other healthcare providers.
