Impact of SARS-CoV-2 vaccination on CD4+ and CD8+ T lymphocyte profiles in an HIV-positive and HIV-negative female cohort

COVID vaccines don't disrupt existing T-cell immunity in HIV-positive women, providing reassurance for safe vaccination in this vulnerable group.

In a cohort of 40 South African women (68% HIV+, 50% vaccinated), SARS-CoV-2 vaccination did not substantially alter CD4+ or CD8+ T lymphocyte levels irrespective of HIV status, suggesting the vaccine does not significantly perturb existing T-cell immunity in this population. The finding provides reassurance for vaccine safety in HIV-affected women but is limited by small sample size.

Why it surfaced

HIV+ women in South Africa are high-priority underserved population; vaccine safety data in this group is valuable; n=40 limits conclusions.
