New COVID-19 Booster for 6m-5y group?

Does anyone know of a location, public or private, that is offering the new COVID-19 booster for the youngest age group? Our pediatrician's office doesn't have it, and doesn't know when or if they'll have it due to questions around insurance. American healthcare FTW! I've also called the public health departments for some of the local counties and none of them have it either.

CVS/Walgreens/etc. are not an option for the youngest age group, most of them only do people 12+, and none of them do babies/toddlers.
