The mother really didn’t keep up on the vaccinations ... :-) ...
Which doesn’t mean the child wasn’t vaxd in the hospital on day 1 of life. They do that regardless of whether you want it or not. Unless mom was in the room with the baby 24hrs a day consider it done. I know a neonatal nurse who brags about getting the infants with that one regardless of whether the parents consent or not. She’s a do-gooder. She’s certainly not alone. Hospitals get extra bennies if they’re 100% for that vax series at birth.
