Steps after NVC??

[RR136 5]

I was hoping to get some insight abt my situation from VJ friends here,

1. I'm collecting all the vaccination records for my wife(beneficiary) and she only has records until she turned 1. I looked up on CDC website and found out the panel physicians in her age group look for Dtap, MMR and Varicella. She has had Dtap vaccine,and had chickenpox when she was young so Varicella should be good too but never had MMR. Can I ask her to get MMR shot through her primary physician or should I wait till the medical appt. with panel physican??

2. She had a problem with her surname left blank on her passport. NVC informed me it should't be a problem until she arrives in US, but upon inquiring how to fix her name on NVC file(they have it as xxxx,FNU)told me to obtain a new passport with corrections. At this stage, is it wise to obtain a new passport for her?? NVC did inform me that even if the case is completed before she gets the new passport,she can take it her interview and inform them about the change and they will stamp the visa with corrected name. Anybody had new passport obtained right before interview?

Any insights would be highly appreciated

Thanks
