MONDAY Now Your Blood Donation Also Helps Fight Crippling Polio! NEW USE FOR GAMMA GLOBULIN HELPS PREVENT CRIPPLING EFFECTS OF POLIO GIVE BLOOD NOW! GAMMA GLOBULIN TAKES 3 MONTHS TO MAKE! MUST BE READY IN TIME FOR PEAK POLIO SEASON! Controlled medical tests show that Gamma Globulin has often helped prevent the crippling paralyzing effects of Polio. (The major use of Gamma Globulin up to this time has been in the prevention and control of measles and infectious hepatitis.) By injecting children with Gamma Globulin the incidence of paralysis in Polio has been greatly reduced. Gamma Globulin is made from human blood. Blood that only you can give. WHAT IS GAMMA GLOBULIN? amma Globulin is that part of human blood which contains "antibodies" built up in the blood stream as the result of the human body fighting disease. Long after the invading Polio virus is gone, "antibodies" remain in the blood—sometimes for life! By collecting this concentrated substance which contains the "antibodies" and inoculating persons with it, Gamma Globulin has greatly reduced the crippling effects of Polio in many cases treated. YOU MAY HAVE HAD POLIOI You may have had mild Polio . . . but never knew it. (Most of us have been exposed to Polio . . . and successfully fought it off without developing paralysis.) What happened? Simply this: When Polio virus t must be stressed that Gamma Globulin is not a "cure-all." How ever, recent field tests scientifically demonstrate that Gamma Globulin does give temporary protection lytic effects of Polio. entered your body, certain cells produced "antibodies" which are still in your blood. These protective "antibodies" either dissolved the Polio virus or helped your white blood cells destroy them. GAMMA GLOBULIN NOT A "CURE-ALL" here is now not nearly enough blood available for Polio use . . . especially if an epidemic should again strike this summer. STOCK PILE CRITICALLY LOW Because it takes one pint of blood to make one dose of Gamma Globulin for the average child . . . and because Gamma Globulin protection lasts only a short time . . . it is obvious that more and more blood is urgently needed. "LATER" WILL BE TOO LATE! Since Gamma Globulin must be processed or "fractionated" from pooled blood derivatives, it takes three long months before your blood can be made into Gamma Globulin. That's why it is important that you give blood now! Yes, helping prevent Polio is one more reason—a powerful, compelling reason—why you should give blood NOW! If enough blood can be secured quickly. America's desperately small stock pile of Gamma Globulin may be built up in time for the peak Polio season ahead. ARMED FORCES GET WHOLE BLOOD FIRST s it should be, our Armed Forces get first call on all blood donated. Because if a badly wounded American soldier doesn't have whole blood immediately, he dies. Blood is needed at home, too-for the hospitalized veteran-for emergencies and disasters on the home front-and to help build up a reserve that is large enough and mobile enough to see us through possible enemy attack. Yes, your blood donation not only helps fight Polio, but serves all America because . . . the blood you give is used wherever it is needed most—first! GIVE BLOOD NOW! Give It Again and Again!
