evidence: Vaccination with a SARS-CoV-2 mRNA vaccine revealed HIV hiding in immune cells in blood from people with HIV, according to lab research led by Weill Cornell Medicine investigators. The findings, published Aug. 19 in Nature Communications, identify new tools for evaluating treatment approaches in development aimed at curing HIV. [...] For their research, the investigators, including co-first authors Eva Stevenson, Sandra Terry and Dennis Copertino, members of Dr. Jones’ lab, treated blood from individuals with HIV who were unvaccinated and had never had COVID-19 to the Pfizer-BioNTech or Moderna COVID-19 mRNA vaccine in test tubes. The Pfizer-BioNTech vaccine produced a greater release of HIV RNA.
