Comorbidity Burden and Suboptimal Immunological Responses to Coronavirus Disease 2019 Vaccination in People Living with Human Immunodeficiency Virus.

To theEditor - We were very interested to read the article by Lapointe et al [[1]] regarding the ability of people with human immunodeficiency virus (HIV) (PWH) to mount an efficient antibody response to coronavirus disease 2019 (COVID-19) vaccine. After 7 months, the PWH had a mean (SD) anti-S IgG titer of 309 (216) BAU/mL, whereas the mean anti-S IgG titers of the HCWs at 4 and 10 months were 1218 (649) and 361 (368) BAU/mL, respectively. Anti-S1 spike protein (anti-S) immunoglobulin (Ig) G antibody titers in people with human immunodeficiency virus (PWH) and healthy healthcare workers (HCWs) over time. [Extracted from the article]
