Abstract Objective To compare the efficacy of covid-19 vaccines between immunocompromised and immunocompetent people. Design Systematic review and meta-analysis. Data sources PubMed, Embase, Central Register of Controlled Trials, COVID-19 Open Research Dataset Challenge (CORD-19), and WHO covid-19 databases for studies published between 1 December 2020 and 5 November 2021. ClinicalTrials.gov and the WHO International Clinical Trials Registry Platform were searched in November 2021 to identify… 

Immunogenicity of COVID-19 mRNA vaccines in immunocompromised patients: a systematic review and meta-analysis

Among patients with IC, those with autoimmune conditions and solid organ malignancies are mostly benefited from COVID-19 vaccination, which could aid healthcare policymakers in making decisions regarding the importance of the booster dose or more strict personal protections in the IC patients.

Immunogenicity and efficacy of COVID-19 vaccines in people living with HIV: a systematic review and meta-analysis

Effectiveness of heterologous and homologous covid-19 vaccine regimens: living systematic review with network meta-analysis

Heterologous and homologous three dose regimens work comparably well in preventing covid-19 infections, even against different variants, and an mRNA booster is recommended to supplement any primary vaccine course.

Booster COVID-19 Vaccines for Immune-Mediated Inflammatory Disease Patients: A Systematic Review and Meta-Analysis of Efficacy and Safety

The results show that booster doses are effective in eliciting seroconversion in non-responders, bolstering immunity to COVID-19, and has also not been associated with major adverse events.

COVID-19 vaccine effectiveness among immunocompromised populations: a targeted literature review of real-world studies

Preliminary evidence is provided that the IC population requires greater protective measures to prevent COVID-19 infection and associated illness, hence should be prioritized while implementing recommendations of additional CO VID-19 vaccine doses.

Seroconversion rate after COVID-19 vaccination in patients with solid cancer: A systematic review and meta-analysis.

The authors' review suggests that, compared with healthy individuals, COVID-19 vaccines show favorable immunogenicity and efficacy in patients with solid cancer, and a second dose is associated with significantly improved seroconversion, although it is slightly lower in patientsWith solid cancer compared withhealthy individuals.

COVID-19 vaccine response and safety in patients with cancer: An overview of systematic reviews

This study suggests COVID-19 vaccine response is significantly lower in cancer patients, and considering the emergence of several new variants of SARS-CoV-2 with potential influence on ongoing vaccination programs, there is a need for booster doses to increase the effectiveness of CO VID-19 vaccines.

Immunogenicity and Safety of COVID-19 Vaccines among People Living with HIV: A Systematic Review and Meta-Analysis

The available evidence suggested that the immunogenicity and safety of COVID-19 vaccines among PLWH were acceptable, and there was no significant difference in the seroconversion rates and incidence rates of adverse events between PLWH and healthy controls.

Efficacy and safety profile of COVID-19 mRNA vaccine in patients with hematological malignancies: Systematic review and meta-analysis

Co cohorts with hematological malignancies showed a lower seroconversion rate and antibody titers after receiving COVID-19 mRNA vaccines, and the vaccines were shown to be safe for both patients and healthy controls.

Factors Associated With COVID-19 Vaccine Response in Transplant Recipients: A Systematic Review and Meta-analysis

Transplant recipients compared with the general population have much lower rates of seroconversion upon receiving COVID-19 vaccines, although different types of immunosuppressants may have differential effects.



Safety and Efficacy of COVID-19 Vaccines: A Systematic Review and Meta-Analysis of Different Vaccines at Phase 3

The results indicate that two mRNA vaccine doses prevent SARS-COV-2 infection most effectively, but further research is needed due to the high degree of heterogeneity among studies in this sample.

Epidemiology and outcomes of COVID-19 in HIV-infected individuals: a systematic review and meta-analysis

HIV remains a significant risk factor for acquiring Sars-CoV-2 infection and is associated with a higher risk of mortality from COVID-19, and the beneficial effects of tenofovir and protease-inhibitors in reducing the risk of SARS- CoV- 2 infection and death from CO VID-19 in PLWHA remain inconclusive.

Immunogenicity of Pfizer-BioNTech COVID-19 vaccine in patients with inborn errors of immunity

Systemic autoimmune myopathies: a prospective phase 4 controlled trial of an inactivated virus vaccine against SARS-CoV-2

Sinovac-CoronaVac is safe and has a moderate short-term immunogenicity in SAMs, but reduced compared with CTRL, and it is identified that immunosuppression is associated with diminished NAb positivity.

Poor neutralizing antibody responses in 106 patients with WM after vaccination against SARS-CoV-2: a prospective study

Patients with WM have low humoral response following COVID-19 vaccination, which underlines the need for timely vaccination ideally during a treatment-free period and for continuous vigilance on infection control measures.

Immunogenicity and Safety of the BNT162b2 mRNA COVID-19 Vaccine Among Actively Treated Cancer Patients

The relatively lower antibody titers and lower proportion of seropositive patients, especially among chemotherapy-treated patients, call for continuing the use of personal protective measures in these patients, even following vaccination.
