US - DS160 question

[riclag]

 The DS160 ask whether or not you have a Immediate relative in the USA ?

My wives sister lives there with her husband ,I don't know her status, if she applied for a green card or not  !

I'm not sure if the sister's status matters or not  lol.

Do I still have to answer yes on the form?

 

There is a vaccination question on the form ! I'm not sure if it applies to all visa classifications .

"Do you have documentation to establish that you have received vaccinations in accordance with U.S. law?"

I'm applying for a BI/B2 visa for my wife and daughter  do they need vacc docs ?

Thanks
