Summer programs for HS Freshman

Hi, I’m a freshman in high schooly currently and I’m looking for some summer programs/research opportunities that will be meaningful. I want to study medicine when I’m older and am wondering if there are any good programs/internships that have an emphasis on that? I want to apply to the Research Science Institute when I’m old enough (I think in about a year or two) so anything that would give me some experience with research would be great! Thank you so much
