Yes, from what I know. They follow the basic requirements hospitals have for their employees and students so that you have no problem transitioning from 2nd year to 3rd year.
TBH, just get all your physicals and vaccinations up to date now when you are free instead of trying to fit it in right before school starts.
We don't want this to turn into a vaccine vs no vaccine debate here, this is not the place (Because people have in the past on SDN). Health professionals require proper preventative care, and vaccines are an important part of it. Expect it to be a part of your employment and career requirements for the remainder of your time as a doctor.
