Older Sister (24F) jealous of my medical school acceptances (20F); not sure how to get her to stop being mean about it

Hello, I hope this is the right place to post...
Growing up my older sister Kelly was everything my parents wished I was. She always got good grades without much effort, popular, pretty,etc. I was ,well, not all that. It wasn't until the end of high school I got my act together and I really blossomed in college. I'm actually currently a senior about to graduate and spent this last year applying to medical schools. I've already gotten a few acceptances although i'm still waiting to hear back from the rest.
​
Anyways, Kelly is extremely jealous and has been nothing but rude during this process. I realized quickly that it would be a sensitive subject for her because her life long dream was to become a surgeon. Unfortunately, she's applied for 2 cycles and has not gotten an acceptance anywhere. I sympathize because I know how tough the process is just to get to med school. Anyways, I was always pretty tight lipped because i didn't want to be "rude" and talk about the application process unless she asked specific questions (early on it would just be "how's your Personal statement going", what's your school list,etc). Now that the acceptances have been rolling in i've obviously been sharing my excitement with my parents. She's become extremely jealous and started acting out. She's been putting me down and implying that i don't really know what I want to do because apparently I haven't "worked in the field before" (despite being an EMT for 3 years). She's also made fun of the schools I have been accepted to and keeps mentioning that there's no way I'm going to be accepted to any of the schools i'm still waiting to hear back (most of them ivys-she got into an ivy league for undergrad but I went to my state school so she believes that because i couldn't get in for undergrad there's no way i'll make the cut for med school). She's also been very passive aggressive (there's a huge list that i don't feel like going into detail about). Recently she started a nursing program so she's even been saying stuff about how doctors are useless, don't know anything/don't care about patients,etc. It really irks me and I don't know what to do because it's constant. I only have to endure it when i'm at my parents' house and they both tell me to let it go, and she's just feeling down about not being able to get into med school right out of undergrad and having to do all this extra work to get there. IDK what to do but i'm about to burst and i dont know how to get her to stop.
​
TLDR; sister jealous of my acceptances to med school, how to get her to stop being mean?
