Science/Biology/Medical High School Summer Internship, but going into engineering

It’s a sickle cell research summer internship offered by a highly rated local hospital. It’s quite selective, and seems intensive. I hope to go into some field of engineering in a prestigious college (still not decided on the specifics), but I’m still very intrigued and interested in this program. I’m simply worried that an AdCom might think I’m not focused on a specific field that I plan to study in college. Although the internship does not directly involve engineering, I truly believe that the learning/intensive work/research aspect will benefit me in ways that I will utilize in my future. It also doesn’t hurt that I could potentially make upwards of $3000 and get published state/nationwide.
What are your thoughts/opinions?
Should I apply for this internship or engineering summer camps (these will most likely be out of state and definitely more expensive)?
Also, if anyone knows of other general opportunities that would be beneficial, please share.

I would say go for it. It sounds like a great opportunity and engineering and medicine are related enough to make a good comparison. Plus, who says you only have to be interested in ONE path? I don’t think it will hurt you in admissions at all, unless your essay is about your undivided love for engineering and how nothing in the world matters to you but engineering.

Ad coms expect high school student to explore different interests – they don’t think that everyone is fully formed in knowing their exact major and career plans when they apply for college. I would not worry about this AT ALL. This sounds like a great opportunity. But if you aren’t guaranteed to get in, make sure you have a backup plan.
