Abstract
OBJECTIVES:: Many vaccines require higher/additional doses or adjuvants to provide adequate protection for people living with HIV (PLWH). Here, we compare COVID-19 vaccine-induced antibody neutralization capacity in PLWH vs. HIV-negative individuals following two vaccine doses. DESIGN:: In Canadian prospective observational cohorts, inlcuding a multi-centre study of PLWH receiving ≥2 COVID-19 vaccinations (mRNA or ChAdOx1-S), and a parallel study of HIV-negative controls (Stop the Spread Ottawa Cohort), we measured vaccine-induced neutralization capacity 3 months post-dose 2 (± 1 month). METHODS:: COVID-19 neutralization efficiency was measured by calculating the half maximal inhibitory dilution(ID50) using a high-throughput protein based neutralization assay for Ancestral(Wuhan), Delta and Omicron (BA.1) spike variants. Univariable and multivariable quantile regression were used to compareCOVID-19-specific antibody neutralization capacity by HIV status. RESULTS:: Neutralization assays were performed on 256 PLWH and 256 controls based on specimen availability at the timepoint of interest, having received 2 vaccines and known date of vaccination. There was a significant interaction between HIV status and previous COVID-19 infection status in median ID50. There were no differences in median ID50 for HIV+ vs HIV-negative persons without past COVID-19 infection.For participants with past COVID-19 infection, median ICD50 was significantly higher in controls than in PLWH for Ancestral SARS-CoV-2 and Omicron variants, with a trend for the Delta variant in the same direction. CONCLUSION:: Vaccine-induced SARS-CoV-2 neutralization capacity was similar between PLWH vs HIV-negative persons without past COVID-19 infection, demonstrating favourable humoral-mediated immunogenicity. Both HIV+ and HIV-negative persons demonstrated hybrid immunity. FUNDING:: Public Health Agency of Canada, through the Vaccine Surveillance Reference group, the COVID-19 Immunity Task Force (2122-HQ-000075) and the CTN. Production of COVID-19 reagents was financially supported by National Research Council of Canada (NRC) Pandemic Response Challenge Program. TRIAL REGISTRATION:: clinicaltrials.gov NCT04894448
