The 4th of July holiday reportedly put a dent in the American Red Cross blood supply.  The holiday weekend caused there to be 550 fewer Blood Drives than normal, according to a WKBW News Report.   According to the article, about 20% of blood drives take place at colleges and high schools; so with the holiday many people are on vacation and blood donation is not a priority.

The most prevalent lack of blood is Type-O Blood, which is the universal blood type used in Emergency Rooms in hospitals across the entire Country for Emergency Room patients, according to reports.  Every two seconds of everyday someone needs blood.
