Conditions

An outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection was dispersed in many countries, which subsequently resulting in global pandemic. According to the contagious and virulence profile of this virus, it was contributed to high morbidity and mortality among patients who were infected. The risk of mortality from COVID-19 disease appears to be higher in patients with aged over 70 years old, taking immunosuppressive agents and whom with pre-existing medical comorbidi

Interventions

All eligible participants will be assessed for general demographic data, and hemodialysis data. The immunogenicity of SARS-CoV-2 vaccination, and the laboratory assessment which might associated with
Homologous inactivated vaccine against SARS-CoV-2 (Sinovac/ CoronaVac) regimen, SV-SV,Homologous replication-defective viral vectors against SARS-CoV-2 (AstraZeneca) regimen, AZ-AZ,Heterologous prime

Design outcomes

Primary

MeasureTime frame
The percentage of participant who has seroconversion of neutralizing antibodies to live SARS-CoV-2 at day 28 after the second dose of each vaccine regimen at 4 weeks after second vaccination Percentage of neutralizing antibody

Secondary

MeasureTime frame
To determine the geometric mean titers (GMTs) of neutralizing antibodies to live SARS-CoV-2, RBD-specific IgG, and S-specific IgG at specific timepoint of each vaccine regimen 4 weeks after first vaccination, pre-second vaccination, and 4 weeks after second vaccination SARS-CoV2 anti-RBD IgG assay, and SARS-CoV-2 NeutraLISA surrogate neutralization assay ,To determine factors associated with seroconversion 4 weeks after the second vaccination Logistic regression,To determine the safety endpoint which are the frequency and intensity of local and systemic adverse events of each vaccine regimen after the first, and second vaccination Vaccine diary
