The Food and Drug Administation altered its policy prohibiting blood donations from men who have sex with other men following pressure from activists and a petition that ammassed more than 20,000 signatures.

In the petition, which was created by the Gay and Lesbian Alliance Against Defamation (GLAAD), the LGBTQ+ organization urged the FDA to reasses the “antiquated” policy which says men who are gay, bisexual, or have sex with other men cannot donate blood unless they have abstained from sex for at least 12 months. On Thursday, the FDA released a revised version of the policy which changed the time period from 12 months to 3.

The change comes at a time when blood donations are in high-demand as part of relief efforts for the coronavirus pandemic. During a White House press briefing on March 19, Surgeon General Dr. Jerome Adams urged people to donate blood and plasma, specifically calling on millennials and Gen Z. Soon after, several people pointed out the FDA’s policy, which stem back to 1983 during the HIV/AIDs crisis.
