Several factors contribute to continued pediatric infections, including ART nonadherence, the emergence of drug-resistant HIV strains, acute infection during breastfeeding, and poor access to ART in resource-limited areas. A better understanding of the maternal humoral immune responses that provide protection against postnatal transmission in the setting of ART is critical to guide the design of maternal vaccine strategies to further eliminate postnatal HIV transmission. In this study, we found that in women treated with antiretrovirals during pregnancy, there was a positive correlation between plasma viral load and breast milk and plasma IgA responses; however, conclusions regarding odds of MTCT risk were limited by the small sample size. These findings will inform future studies to investigate maternal immune interventions that can synergize with ART to eliminate MTCT during breastfeeding.<\/jats:p>","DOI":"10.1128\/msphere.00716-19","type":"journal-article","created":{"date-parts":[[2019,10,29]],"date-time":"2019-10-29T11:15:54Z","timestamp":1572347754000},"update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":7,"title":["Maternal Humoral Immune Responses Do Not Predict Postnatal HIV-1 Transmission Risk in Antiretroviral-Treated Mothers from the IMPAACT PROMISE Study"],"prefix":"10.1128","volume":"4","author":[{"given":"Eliza D.","family":"Hompe","sequence":"first","affiliation":[{"name":"Duke University School of Medicine, Durham, North Carolina, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Denise L.","family":"Jacobson","sequence":"additional","affiliation":[{"name":"Center for Biostatistics in AIDS Research, Harvard T.
