Since 1983, during the height of the AIDS epidemic, the federal government instituted a lifetime ban on blood donations from gay men. In 2015, the rule was replaced with a year-long abstinence requirement. Due to the severe shortage of blood donations caused by coronavirus fears, as of April 2, 2020, the Food and Drug Administration revised its blood donor guidelines to relax the abstinence requirement for gay and bisexual men to 90 days before they are eligible to donate blood. According to the NBC News article, the FDA also relaxed 12-month deferral periods for certain world travelers, "those who have engaged in injection drug use and people who have participated in commercial sex work."
Though people infected with HIV are still ineligible from donating blood, allowing some healthy gay men to start donating blood is a step in the right direction.
