Matched vs. Unmatched t-tests

I am conducting a t-test and have to choose between an unmatched and matched test. I am looking at the vaccination percentage rate between men and women in a given year. Would this be a matched test? My understanding is that in a matched test, the two variables need to be independent, but I am still unsure.

Thank you for the help.

Seemingly, you do have a dichotomous outcome (vaccinated yes/no).
If you want to compare rates (relative frequencies) between the sexes,
you can cross-tabulate and use a Chi2 test.
