Doctor: Mom is all clear, but Joanna tested positive for the measles virus.
Daisy: No, that's impossible. She had the vaccine.
Doctor: The vaccine protects 93% of people. That's why we give the booster at age 4. Because she is contagious, we're going to move both of you to a quarantined location.
Daisy: But she's going to be okay, isn't she?
Doctor: We'll do everything we can to get her through it, but she's going to be very sick within the next few days.
