Background: The effect of booster vaccinations with the coronavirus virus disease (COVID-19) vaccine on people living with HIV (PLWH) remains unknown. In this study, we aimed to investigate the immunogenicity and effectiveness of booster doses of the COVID-19 vaccine in PLWH.
Methods: Literature research was done through the PubMed, Embase, Cochrane Review, and Web of Science databases up to 4 July 2023. Pooled estimates were calculated and compared using the DerSimonian and Laird method for a random effects model. Randomized control trials and observational studies were both considered for inclusion.
Results: We included 35 eligible studies covering 30,154 PLWH. The pooled immune response rate (IRR) of PLWH after the COVID-19 booster vaccination was 97.25% (95% confidence interval [CI], 93.81-99.49), and similar to healthy control (HC) (risk ratio [RR] = 0.98, 95% CI, 0.96-1.00). The pooled IRR for PLWH with CD4 T-cell counts ≤ 200 was 86.27 (95% CI, 65.35-99.07). For Omicron variants, the pooled IRR for PLWH after booster dose was 74.07% (95% CI, 58.83-89.30), and the risk of IRR was reduced by 10% in PLWH compared with HC (RR = 0.90, 95% CI, 0.80-1.00). The T-cell immune response of PLWH was found to be comparable to HC ( ≥ 0.05). Subgroup analyses revealed that mRNA vaccines produced a relatively high IRR in PLWH compared to other vaccines. In addition, the results showed that booster vaccination appeared to further reduce the risk of COVID-19-related infections, hospitalizations, and deaths compared with the primary vaccination.
Conclusion: It was shown that booster vaccination with the COVID-19 vaccine provided a high IRR in PLWH and still produced a desirable moderate IRR in PLWH with a CD4 T-cell count of ≤ 200. Importantly, the humoral and T-cell responses to booster vaccination in PLWH were comparable to HC, and similar results were observed with the SARS-CoV-2 Omicron variant. Our review strongly emphasizes the effect of mRNA vaccine booster vaccination in PLWH on eliciting desirable protective IRR. Furthermore, booster vaccination appears to further reduce the risk of COVID-19 infection, hospitalization, and death in PLWH compared to primary vaccination. However, more evidence is needed to confirm its effectiveness.

Background: Significant heterogeneity has been reported in estimates of long-term sequelae following SARS-CoV-2 infection in pregnant women, and most studies were conducted pre-Omicron and pre-dated vaccination rollout. Less severe COVID-19 attributed to milder Omicron may potentially attenuate risk of post-COVID-19 sequelae.
Objective: We sought to examine long-term risk of new-incident multi-systemic sequelae following SARS-CoV-2 Delta/Omicron infection in a population-based cohort of pregnant women, contrasted against a)test-negatives; b)infected non-pregnant women of childbearing age.

Human clinical trials have reported immunological outcomes can differ between ipsilateral (same side) and contralateral (alternate sides) prime-boost vaccination. However, our mechanistic understanding of how keeping or shifting the anatomical sites of immunization impacts the resultant germinal centers (GCs) and antibody responses is limited. Here, we use an adjuvanted SARS-CoV-2 spike vaccine to dissect GC dynamics in draining lymph nodes and serological outcomes following ipsilateral or contralateral prime-boost vaccination in C57BL/6 mice.

Assessing knowledge of HPV and HPV vaccine and vaccine willingness among Beijing secondary school parents, and identifying decision-influencing factors. Selected via multi-stage stratified sampling, 3,081 Chaoyang secondary school students' parents participated in a June-August 2024 study. They completed a questionnaire assessing HPV knowledge, vaccine awareness, and vaccination willingness.

Background: Booster doses of COVID-19 vaccines are required to maintain protection against SARS-CoV-2. However, real-world evidence from South America, needed to inform optimal vaccination strategies, is lacking. Herein, we present the final analysis of REFORCO-Brazil, a large-scale assessment of relative vaccine effectiveness (rVE) of second boosters (vs first boosters) against hospitalization with COVID-19.
