In April 2020, this restriction was relaxed to 4\u2009months due to the lack of negative impact observed on blood safety.

For all three viruses, residual risks of transmission by transfusion did not increase: HIV (1\/7,800,000 donations vs. 1\/10,500,000), HCV (1\/25,200,000 vs. 1\/47,300,000) and HBV (1\/6,400,000 vs. 1\/6,000,000).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Reducing the deferral period for MSM in April 2020 did not negatively impact residual risks, which remained very low, or the rate of positive donations, except for syphilis, which requires careful monitoring. To ensure equal access to blood donation, MSM have been allowed to donate blood under the same conditions as other donors since March 2022 (i.e., no more than one sexual partner in the last 4\u2009months).<\/jats:p><\/jats:sec>","DOI":"10.1111\/vox.13726","type":"journal-article","created":{"date-parts":[[2024,9,1]],"date-time":"2024-09-01T23:58:51Z","timestamp":1725235131000},"page":"1150-1157","source":"Crossref","is-referenced-by-count":4,"title":["Impact of recent criteria changes for the deferral criteria specific to men who have sex with men in France"],"prefix":"10.1111","volume":"119","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1664-9691","authenticated-orcid":false,"given":"Claire","family":"Sauvage","sequence":"first","affiliation":[{"name":"Sant\u00e9 publique France  Saint\u2010Maurice France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6497-0108","authenticated-orcid":false,"given":"S.","family":"Laperche","sequence":"additional","affiliation":[{"name":"\u00c9tablissement fran\u00e7ais du sang  Saint\u2010Denis France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"V.","family":"Corominas","sequence":"additional","affiliation":[{"name":"Centre de Transfusion Sanguine des Arm\u00e9es  Clamart France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"K.","family":"Stefic","sequence":"additional","affiliation":[{"name":"Centre National de R\u00e9f\u00e9rence du VIH \u2013 Laboratoire associ\u00e9, Inserm U1259 CHU Bretonneau &amp;
