Although it's possible to reapply in the match for the next year, it isn't easy. First, if you went on a bunch of interviews this year and ended up low on your list, what are you going to change to get a different result?
Second, you'll be an intern in a program. How exactly do you plan on going on enough interviews? This is not medical school, you are getting paid to do a job. Your program is unlikely to just give you days off to interview. You could ask for a vacation during interview season, but it depends how that works. We have our residents take a 2 week and 1 week vacation (and then they get holiday time off), you might find it very difficult to arrange interviews during vacation.
Third, many programs won't take someone who has already completed an intern year. Completing an intern year is lots of work, but a great learning experience. The first time. If you do it again, it's all drudgery and work. Plus there are funding issues.
Last, the match is in March. Your current program is likely going to want you to commit to a PGY-2 before then. They might find a replacement before you have matched somewhere else. You could end up with nothing. (Some programs might hold your spot until post match).
Your best option is to make the best of what you've got. Be the best resident they have ever had. You can build an academic career coming from a busy community hospital. You could try to transfer as a PGY-2, there's no match and you can hunt around.
