No Increased Risk of Blood Donations from MSM after Temporary Deferrals

June 29, 2016

Most industrialized countries do not allow blood donations from men who have had sex with men (MSM). Recently, however, several countries have changed their policies to allow blood donations from individuals that have abstained from MSM behavior for one year (e.g., United States, United Kingdom, and Australia) or five years (e.g., Canada).  Two studies published in TRANSFUSION evaluated the impact of temporary deferral policies for MSM behavior on the blood supply.  In the first study, four previously published mathematical models predicted increases in the rate of HIV positive donations from 73% to over 3400% in the United Kingdom, Australia and Canada.  However, the observed rate of HIV positive donations did not increase during the two years after temporary deferral for MSM behavior (16 cases/year) compared to 22 cases/year before the policy was implemented.  A second study also found the rate of HIV positive donations to be similar in Canada both before and after the 5-year deferral policy went into effect.  Further monitoring of transfusion-transmitted infections is planned in the United States over the next 5 years to ensure policy changes do not affect blood safety.

    In 2009, the Pan American Health Organization (PAHO), published “ELIGIBILITY FOR BLOOD DONATION” Recommendations for Education and Selection of Prospective Blood Donors”. In the section on “RISKY PRACTICES”, under ‘Sexual Behaviors” (pages 34/35), men having sex with men is considered high risk. The PAHO recommendation is “Persons who engage in risky sexual behaviors should be deferred from donating blood for 12 months after the last occurrence”. PAHO should receive the credit it deserves for its pioneering role.
