UF will charge your student for health insurance, unless you complete the online waiver. This has to be done on a yearly basis.

Insurance Waiver Deadlines:
Summer A/C – May 24th, 2019
Summer B – July 12th, 2019

Also, I noticed that UF has updated the financial aid info for Summer 2019 (this is for the 2018 to 2019 term). It now includes any projected Bright Future scholarships and student loans (and perhaps grants, etc). With the student loans, you will need to accept, reduce or decline the loans. BF does now pay for summer classes, but it doesn’t pay the $300 a semester for books, etc.
EDIT: To be eligible for summer 2019 Bright Futures, you must be enrolled in a minimum of 6 credit hours across all summer sessions (It’s 12 credits for Fall/Spring terms).
