up at my son's pediatrician's office to get that shot in his little arm. 5 to 11-year-olds are far and away the least vaccinated group -- age group by percentage. should there be a new strategy, doctor, to get this youngest group protected in the way they need to be? >> right. so you're exactly right. more access to vaccines is wonderful but the real deal here is vaccination. we need shots in those arms and so the strategy might need to be different. we have definitely reached a very granular level of the pandemic where there are so many different groups out there who have heard so many different messages. unfortunately for many in the parent category, it's disinformation. so the one-to-one conversations, the community support is going to be so very vital. again, this is going to be a granular level approach. family practice doctors, pediatricians understand the benefit of vaccines.
