COVID-19 Vaccines and COVID-19 in People Living with HIV.

Objective: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spread rapidly around the world, and COVID-19 and HIV co-infection also became common. In this study, we aimed to investigate the impact of vaccination preferences and vaccination rates on the severity of COVID-19 in patients with HIV co-infection.

Materials and methods: People living with HIV who were followed in our hospital during the COVID-19 pandemic (January 2020- December 2022) were retrospectively included in the study. The diagnosis of COVID-19 was made by detecting SARS-CoV-2 RNA in nasopharyngeal swab specimens using real-time reverse transcriptase-polymerase chain reaction (rRT-PCR). Patients requiring hospital admission were classified as severe. The patient's demographics and vaccination status were collected from the hospital data system.

Results: Our study included 205 patients using antiretroviral therapy for HIV. The mean day count between the last vaccine date and SARS-CoV-2 PCR positivity was 163 days in the Comirnaty® group,149 days in the CoronaVac® group, and 154 days in the mixed-vaccinated group. Those vaccinated with Comirnaty® were statistically significantly less infected with COVID-19 after vaccination (p<0.05).

Conclusion: The course and the outcomes of COVID-19 among SARS-CoV-2 vaccinated people living with HIV, especially with well-controlled HIV infection, seem to be similar to people living without HIV.
