Going to California for Christmas.

Every year we always go to California to spend Christmas with hubby's family. This year we planned on traveling this coming Saturday and spend 15 days there but Maddie's flu vaccine is re-scheduled this coming 21st. Hubby wanted to know if Maddie can get the shot in Kaiser California for us to travel as plan. I tried calling Kaiser but they said they will call me. Unfortunately, I haven't receive a call from the nurse that I spoke last Friday. Let's see what is hubby's plan.
