There are also contradictory findings 27 on the severity of COVID-19 in PLWH, though two recent meta-analysis suggested that 28 PLWH have a higher risk of death from COVID-19 [1, 2] . On the contrary, the BNT162b2 were identified from a prospective cohort followed in our centre. A parallel group of 38 COVID-19 controls was recruited among consecutively seen patients attended as 39 outpatients after admissions due to COVID-19 or after being referred from Primary 40 Care or the Emergency Room (March 8 th , 2020-July 30 th , 2020) or their infected 41 contacts. The PLWH cohort is followed, at least, every 6 months. The control group 42 was scheduled for follow-up 3 and 6 months after COVID-19. COVID-19 severity was 43 assessed for all individuals (Appendix A). All serum samples collected at each visit were 44 tested for SARS-CoV-2 total serum antibodies (ELECSYS TM Anti-SARS-CoV-2, Roche 45 Diagnostic International, Rotkreutz, Switzerland). All serum samples collected 6 46 months after COVID-19 were tested for anti-spike antibody levels (Appendix A). 47 statistically significant difference in the median age and the sex distribution between 50 PLWH and controls. The severity of COVID-19 and the Charlson index were similar 51 between groups. After 6 months, the proportion of PLWH with detectable SARS-CoV-2 52 total serum antibodies was 86% [95% confidence interval (95% CI): 75%-93%] and the 53 frequency of thereof for controls was 98% (95% CI: 93%-99.8%) ( Table 1 ). The 54 difference in the frequency of detectable antibodies was -12% (95% CI: -6.8%, -18%). 55 This was mainly due to a higher rate of antibody seroreversion among PLWH (Table 1) . 56 The anti-spike antibody titers were significantly lower for PLWH (Table 1) immunogenicity of other vaccines in PLWH. All PLWH in the present study were on 95 counts. However, nadir CD4 cell counts were relatively low. Thus, incomplete humoral 97 immune restoration induced by antiretroviral therapy is a possible reason for this 98 study results. 99 HIV infection and risk of COVID-19 123 mortality: A meta-analysis Epidemiology and outcomes of COVID-19 in HIV-infected individuals: a 126 systematic review and meta-analysis Immunogenicity and safety of the BNT162b2 mRNA Covid-19 vaccine in people 129 living with HIV-1.
