I got the shot and then about 30 minutes later, I photocopied the document and mailed it off. I just found out this morning that the tetanus immunization record was due March 5th, so I decided not to waste any time. It was a real close call, because the immunizations are no longer given after 12:30pm, but I didn't receive mine till about 12:45pm. The post office closes at 2pm and I was having printer problems when I got home, I just barely mailed off the forms at 1:20pm.
