Tainted: Why Gay Men Still Can't Donate Blood
- "Since 1983, Food and Drug Administration (FDA) guidelines have disqualified men who have ever had sex with men (MSM) from donating blood... Uneven application of exclusion to at-risk individuals suggests that risk aversion disproportionately impacts MSMs. For example, a non-MSM individual who has had sexual contact with a commercial sex worker or HIV-positive partner is deferred for only twelve months... The fact that the U.S. upholds a lifetime ban on MSM donation while Australian policy allows MSM individuals to donate a year or less after contact reveals a glaring discrepancy. Both ethics and science point to a flaw in FDA policy. That I could have had sex with 365 partners this year and be a perfectly fine candidate for donating blood, while the MSM next to me wouldn't qualify, betrays a faulty line of logic." [more inside]
