Can I get one for Harmony???

We are delaying vacs, but have a massive outbreak of whooping cough up here, and am waiting for a call back from some public health dude to let me know if he can get her one.....
My girlfriend called and there are a few cases of it at her sons preschool already, and we are having a B'day party for our now 3 yr old this weekend...... so with lots of other kids around, I'd like Harmony vac's for it....
(none of my kids are in care though)
