10 month &MMR vaccine

We will be leaving Saturday to Alaska.

Her dr wasn’t available but a PA saw her and told us we should consider giving her the MMR shot tomorrow.

I’m a little scared as I’ve heard good/bad stories about it. I know they are supposed to wait till 12 months but because we are going on this trip they are considering it.

Please let me know your thoughts!! We have to make a decision tomorrow.
