MVA.HIVconsvX vaccination-evoked T cell expansion inversely associates with age in people with HIV-1 on antiretroviral therapy.
Trial report in The Journal of clinical investigation, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
BACKGROUNDApproaches to achieving antiretroviral therapy-free (ART-free) remission from HIV-1 must consider that people over 50 years now comprise the majority of people with HIV (PWH) on ART in various regions, including the United States.METHODSWe report a double-blind, randomized trial in which PWH on ART, aged 21-60 years, received modified vaccinia Ankara-vectored (MVA-vectored) vaccines, MVA.tHIVconsv3 (M3) and MVA.tHIVconsv4 (M4), either alone or in combination (n = 7/group), or saline placebo (n = 3). M3 and M4 contain complementary HIVconsvX immunogens that each span the same regions in HIV-1 Gag and Pol but differ by approximately 8% at the amino acid level.RESULTSM3, M4, and M3M4 regimens were well tolerated and all significantly increased both the frequency (peak median increase ~3-fold) and breadth of the HIVconsvX-specific T cell response while redirecting T cells to target conserved regions in HIV-1 for up to 10 weeks after vaccination. We also demonstrated that vaccination increased frequencies of T cells targeting participant autologous HIV-1 sequences. Vaccination mostly expanded preexisting HIV-1-specific T cells and did not impact CD4+ T cell activation, low-level viremia, or integrated HIV-1 provirus. Linear regression indicated that age was independently and negatively associated with the change in T cell frequency at 1, 2, and 10 weeks after vaccination (~1.41-fold decrease per 10 years older). After adjusting for age, years on ART was positively associated with HIVconsvX-specific T cell frequencies at 1 and 2 weeks following vaccination.CONCLUSIONIn PWH receiving ART, MVA.HIVconsvX vaccines significantly increased T cells targeting conserved regions of HIV-1. Novel strategies may be required to enhance anti-HIV-1 immunity in older adults.TRIAL REGISTRATIONClinicalTrials.gov NCT03844386FUNDINGNIH National Institute of Allergy and Infectious Diseases (NIAID) grants U01AI131310, HHSN272201100021I/HHSN27200037 (subcontract OX-14007.004.0037-212), UM1TR004406, P30AI050410, and P30CA016086; International AIDS Vaccine Initiative; European and Developing Countries Clinical Trials Partnership SRIA2015-1066; European Commission's Horizon 2020 Research and Innovation Programme 681137.
