The study aimed to assess the effectiveness of COVID-19 vaccines in people living with HIV compared to a matched HIV-negative cohort. Using data from the British Columbia COVID-19 Cohort, the study found that the vaccine effectiveness against SARS-CoV-2 infection was 71.1% seven to 59 days after two doses, increasing to 89.3% between 60 and 89 days. However, noticeable waning was observed, with effectiveness dropping to 51.3% after 4-6 months.
Objectives: We estimated the effectiveness of COVID-19 vaccines against laboratory-confirmed SARS-CoV-2 infection among people living with HIV (PLWH) and compared the estimates with a matched HIV -negative cohort.Methods: We used the British Columbia COVID-19 Cohort, a population-based data platform, which inte-grates COVID-19 data on SARS-CoV-2 tests, laboratory-confirmed cases, and immunizations with provin-cial health services data. The vaccine effectiveness (VE) was estimated with a test-negative design using the multivariable logistic regression.Results: The adjusted VE against SARS-CoV-2 infection was 71.1% (39.7, 86.1%) 7-59 days after two doses, rising to 89.3% (72.2, 95.9%) between 60 and 89 days. VE was preserved 4-6 months after the receipt of two doses, after which noticeable waning was observed (51.3% [4.8, 75.0%]). In the matched HIV-negative cohort (n = 375,043), VE peaked at 91.4% (90.9, 91.8%) 7-59 days after two doses and was sustained for up to 4 months, after which evidence of waning was observed, dropping to 84.2% (83.4, 85.0%) between 4 and 6 months.Conclusion: The receipt of two COVID-19 vaccine doses was effective against SARS-CoV-2 infection among PLWH pre-Omicron. VE estimates appeared to peak later in PLWH than in the matched HIV-negative co-hort and the degree of waning was relatively quicker in PLWH; however, peak estimates were comparable in both populations.
