Hoping you aren't a fourth year already.
But, honestly, I recommend getting all your immunizations up to date and records ready for the spring. Honestly was the bane of applying vsas because the records you have may no suffice. Not only do you need proof you're immunized, but some places require titers/proof of lab results.
Then VSAS becomes easier. Also, when VSAS opens, be on top of your school taking care of their end of things like authorizations or reviews.
These are things no one told me. Like, my school fumbled to get my immunizations.
Also, after you get those, make an appointment with your pcp or school physician. Do NOT take the risk and let an NP or PA sign off.
Also, make sure that when you get your influenza vaccine, you get the information from the vaccine like manufacturer, lot, etc.
I was lucky and the physician I had just signed the blank forms because he understood. Actually, he just gave me his email address and told me to send the PDF documents and he'd digitally sign them. Some places are annoying.
