How this longtime Red Cross volunteer helped end the FDA's ban on gay men donating blood

Ralph Galvan has been a volunteer with the American Red Cross for 10 years. But as a gay man, it wasn't until last year that he was able to donate blood.

Rules the Food and Drug Administration had in place since the 1980s HIV-AIDS crisis kept sexually active gay or bisexual men from donating. To help change that policy, Galvan took part in an FDA-funded study that led to last year's requirement changes. 

"(I) felt really good and really good that, you know, we're not on the sidelines anymore," Galvan told CBS News. "Being part of the advance study and helping shape those things, getting rid of the policy, it's beneficial to me, to my community."
