Do I have to have an appointment or do you all accept drop-in?

Yes, you do need a scheduled appointment.  Each bottle holds a total of 10 vaccines, therefore it is critical for us to have the exact number of people as vaccines.  There are very strict storage and administration guidelines.  The vaccine must remain frozen until time to do the shot.  Once it is thawed we have a six hour window to give the shot.  Once we pull the medicine up into a vial, we have two hours to administer the shot, so appointments are critical.
