The Food and Drug Administration is considering a more individualized strategy for screening gay and bisexual men for blood donation amid an ongoing national blood shortage, according to an official briefed on the proposal.

The FDA has long discouraged men who have sex with men from donating blood. A complete ban was introduced in the 1980s, for fear of HIV. transfer. In 2015, the agency allowed gay and bisexual men to donate if they had not had sexual contact with other men in the previous year.

The period was reduced to three months after severe blood shortages during the Covid-19 pandemic.

The new plan requires men who have sex with men to complete a questionnaire about condom use and recent sexual activity, among other risk factors. The idea, which is still up for debate, would be to allow those who haven’t found new partners in the past three months to donate.

The strategy was first reported by The Wall Street Journal. In a statement on Wednesday, the F.D.A. said new data “is likely to support a policy transition to individual risk-based donor screening questions for HIV risk reduction. transfer.”

The outline of the plan is controversial among L.G.B.T.Q. advocates, who say blood donation policies have been discriminatory in the past and that unequal treatment remains a concern.

“However, it is not where it should be. Our community and leading medical experts have been saying for years now that these decisions made by the F.D.A. makes on blood forbidden to the L.G.B.T.Q. community are based on stigma, not science. And we see that pattern continuing here.

The new approach is designed to strike a balance between activists who don’t want restrictions on those single gay and bisexual men and blood banks who want to eliminate the risk of a recipient contracting HIV, the FDA said. official, who requested anonymity to describe the internal discussions.

Several major blood centers are completing an FDA-funded study designed to assess the safety of replacing the current three-month waiting period with a more individualized assessment.

The researchers, who enrolled about 1,600 gay and bisexual men in eight metropolitan areas, hope to identify a set of screening questions that could distinguish men who are more likely to have recently contracted HIV. of those less likely to contract the virus.

Participants in the project, known as the ADVANCE study, answered a variety of questions about their recent risk-related behaviors, such as whether they had new sexual partners or were taking pre-exposure prophylactic drugs known as PrEP, which may increase the risk of HIV infection, said Brian Custer, director of Vitalant Research Institute and principal investigator on the study.

The blood of the participants was also tested for H.I.V. and the antiretrovirals used in PrEP.

The researchers have already shared an interim analysis with the F.D.A. and should have final results ready before the end of the year, said Dr. Custer. He declined to provide more information about the preliminary findings, citing a confidentiality agreement with the FDA, but said he expected the results to be informative for the agency.

“I am really convinced that we have important information for the F.D.A. to be able to consider what an individual risk-based approach to donor selection might look like,” he said.

Susan Stramer, vice president of scientific affairs for the American Red Cross, said in a statement that the study was designed “to make blood donation a more inclusive process while preserving the safety of the blood supply.”

“While we have not been notified by the F.D.A. In terms of policy changes at this time, the Red Cross looks forward to a future where eligibility for donation is not based on sexual orientation, and more healthy individuals can donate blood to help patients in need,” she said.

The current blood shortage is tracked daily by America’s Blood Centers, the industry association for 59 community facilities. On Wednesday, about a quarter of the centres, or 16, had less than a day’s supply in stock.

“In this post-pandemic environment, blood donations organized by companies – in particular – have not returned to pre-pandemic levels as the way people work has changed,” said Nick Gehrig, the senior director for communications at Vitalant , in an email.
