We did the mass at the Vatican many years ago but it was in Italian: so, here's one from a website: ( so I have no actual experience having Mass there)

Santo Spirito in Sassia (near the Vatican)
Sunday Mass Time: 10 am
Chiesa di Santo Spirito in Sassia, Borgo Santo Spirito, 00193

The website is in Italian, but the second line translates to: "Holy Mass in English is offered at 10:00"

As of last summer the Pantheon had a bilingual English / Italian mass on Sunday mornings. Some readings and songs were in English, homily was Italian.
I find going to a local language mass really valuable, even though I don’t understand the words. So if an Italian only mass fits your schedule better, don’t hesitate to go. If you attend mass at home you can pretty much follow along with the order and so know what’s going on.

They have a listing of English Masses in Rome in various locations. There are actually three listed that are near or in the Vatican.

I remembered that there was an American church in Rome I think this is it: american community n rome
