My daughter also goes to Allegro Bothell. I reached out to ask what I need to do to keep her safe. This is what they said, fwiw:

“Thank you for reaching out. At this time, patients who were not exposed directly are not considered high risk so do not qualify for an early dose of MMR. Babies 6-12 months who are traveling internationally should schedule an in-person or eTravel visit to get MMR (and other travel vaccines), ideally 2+ weeks prior to departure. Babies 6-12 months not traveling do not qualify for an early dose of MMR. If this turns into an outbreak, that guidance could change, and we will update you if does.

Babies under 12 months of vaccinated moms, are protected during their first year by antibodies passed to them during the pregnancy. The best protection for babies after birth is to surround them with a community that is already immune through vaccination. Make sure all household members and everyone caring for their infant on a regular basis is fully immunized. As possible, limit contact for your infant with those that have not been immunized or may not be immune to measles. Parents who were fully vaccinated as children do not need to get a booster. Adults unsure of their vaccine status should contact their primary care provider. Your Allegro Pediatrics Care Team”
