Evaluate the Impact, Safety, Tolerability and Immunogenicity of the Coronavac Vaccine in Kidney Transplant Recipients

NCT04801667 | Unknown Phase 4

Brief Summary

Since the beginning of the SARS-CoV-2 pandemic, 1031 (8.7%) of the 11875 kidney transplant recipients being followed up at Hospital do Rim have been infected. The overall lethality rate was 24%, reaching 53% among those over 70 years old. Among the survivors, there is also a high incidence of renal dysfunction with loss of the renal graft and definitive return to dialysis. Patients receiving pharmacological immunosuppression, including transplant recipients, have not been included in the studies carried out to date. In addition, kidney transplant recipients may have reduced vaccine responses compared to the general population. The severity, the high incidence of renal dysfunction and loss of renal graft, and the high lethality associated with COVD-19 justify the investigation of the epidemiological impact and immunogenicity of the vaccine against SARS-CoV-2 infection.

Conditions

SARS-CoV Infection; Coronavirus Infection; Vaccine Adverse Reaction

Outcome Measures

Primary Outcomes (1)

• Evaluate the incidence of hospitalization or death in 28 days associated with COVID-19 (symptomatic cases confirmed virologically by COVID -19 with positive CRP) 14 ± 2 days after the second dose of the vaccine.

  45 days

Secondary Outcomes (6)

• Evaluate the impact of the vaccine on the incidence of COVID-19 according to the severity criterion of the World Health Organization.

  6 months

• Evaluate the impact of the vaccine on the incidence of COVID-19 and hospitalization for COVID-19 disease, confirmed by PCR, for a period of 6 months after the final vaccination.

  6 months

• Evaluate the vaccine's safety, tolerability, and reactogenicity profile: occurrence of signs and symptoms of local and systemic reactogenicity requested seven days after vaccination.

  7 days

• Evaluate the incidence of serious adverse events for a period of 6 months after the final vaccination.

  6 months

• Evaluate immunogenicity by detecting antibodies against SARS-CoV-2 for a period of 6 months after the final vaccination.

  6 months
