Which VPD's to vax for a 4 year old?

[Meems]

I am doing more research and possibly revisiting the idea of very selectively vaccinating my 4 yr old who is unvaxed. 

Here's where I'm at: Are HIB and Pc the biggest threats to her at this age? I know she's close to not needing them, but after hearing about several HIB infections of kids under age 8, I am wondering if she should have this vaccine?

I am thinking of doing the MMR and DTaP at some point in the next year or so.

Any experience or advice would be so helpful! Thanks!
