Correlation between post-vaccinal period and antibody responses in vaccinated PLWH and PLWOH individuals In sera of people who received adenovirus-based vaccines, a negative slight correlation was found between anti-S IgG levels and post-vaccination period with Sputnik/Gam-COVID-Vac vaccinees in both groups of PLWH ( r = -0.26) and PLWOH ( r = -0.27), whereas in Janssen/Ad26.COV2.S, there was a slight positive correlation between anti-S IgG and t post-vaccination period in PLWOH ( r = 0.44) versus a negative trend in PLWH ( r =-0.34) (FIG).
