I understand that you are confused about what to do with vaccinations.
Here is the schedule if you miss vaccination previously,
three doses at 0,1 and 6 mths.
two doses at 0 and 6 mths.
one dose every 3 years.
two doses at 4-8 weeks interval.
You cannot hasten things, for eg you cannot take all doses of Hep B within one month. It is safe and feasible to take hep A, Hep B, Typhoid, Chicken pox all together in a single day. Hep A and B combined together as a single vaccine
is available, so that you need to take only three shots in a single day.
Usually institutions don't debar you from admission provided you give the assurance of completing all doses as per the schedule. Just show them whatever you have taken.
Some institutions require either vaccination record or antibody titers. If so you can check your titers for HepA, as a good number of adults have good antibody titers and don't need vaccination for the same.
Don't worry dear, no one is going to stop you from MBA admission based on only vaccination status. And completing vaccinations are good for your own. Take care.
