People living with HIV (PLWH) are a heterogeneous group of immunocompromised persons. Detectable HIV viral load and chronic comorbidities are independently increasing the risk of severe outcomes from COVID-19 among PLWH. We aimed to assess the efficacy and safety of the COVID-19 vaccines in PLWH. A significant increase in S-RBD antibody titers >100 AU/mL was observed when compared the titers measured one week after the 1st dose to titers performed after the 2nd vaccine dose.
