NCT04984408

Brief Summary

To expand the access and delivery of COVID-19 Vaccines in Africa (ECOVA), the investigators will conduct a phase 3, individually randomized, observer-blind, controlled (influenza vaccine) trial to evaluate the safety and efficacy of the BBIBP-CorV vaccine against any severe acute respiratory syndrome 2 (SARS-CoV- 2) infection among adults 18 years and older. The BBIBP-CorV vaccine is an inactivated SARS-CoV-2 vaccine (Vero cell) manufactured by the Beijing Institute of Biological Products (BIBP), China National Biotec Group (CNBG), Sinopharm, Beijing, People's Republic of China and received emergency use authorization (EUA) from World Health Organization (WHO).

Outcome Measures

Primary Outcomes (1)

  • Protection conferred by BBIBP-CorV vaccine against any COVID-19 disease

    Protection conferred by BBIBP-CorV vaccine against any COVID-19 disease measured as the reduction in incidence of Reverse Transcriptase Polymerase Chain Reaction (RT-PCR) confirmed COVID-19 disease in the BBIBP-CorV vaccine arm (s) compared to the control arm, 7 days after the second dose of study intervention

    Up to two years follow up from the date of enrollment

Secondary Outcomes (13)

  • Incidence of solicited adverse events, unsolicited adverse events and serious adverse events and adverse events of special interest (AESIs)

    local solicited adverse events within 7 days and systemic solicited adverse events within 14 days of each vaccination, unsolicited adverse events within 28 days of each vaccination

  • Protection conferred by BBIBP-CorV vaccine against symptomatic COVID-19 disease

    Till two years follow up from the date of enrollment

  • Protection conferred by BBIBP-CorV vaccine against asymptomatic SARS-CoV-2 infection (any SARS-CoV-2 variant)

    Till two years follow up from the date of enrollment

  • Protection conferred by BBIBP-CorV vaccine against severe COVID-19 disease and COVID-19 associated death

    Till two years follow up from the date of enrollment

  • Geometric Mean Titers (GMT) and Geometric Mean Fold Rise (GMFR) of anti-SARS-CoV-2 neutralizing antibody in subset of participants

    Till two years follow up from the date of enrollment

  • +8 more secondary outcomes

Other Outcomes (5)

  • Acute phase reactants in COVID-19 patients that best predict COVID-19 disease and, hence, the control of protection against COVID-19 infection.

    Till two years follow up from the date of enrollment

  • Profile of the epitope-specific humoral immune response that tracks with protective immunity following natural infection or vaccine-induced immunity, using Systems Serology

    Till two years follow up from the date of enrollment

  • Any pregnancy outcomes after immunization in the intervention arm(s) as compared to control arm(s).

    Till two years follow up from the date of enrollment

  • +2 more other outcomes

Study Arms (3)

Arm 1: BBIBP-CorV

EXPERIMENTAL

Study Arms 1 will have two groups: group 1 - HIV-uninfected receiving BBIBP-CorV; group 2 - HIV-infected receiving BBIBP-CorV .

Biological: BBIBP-CorV - Inactivated SARS-CoV-2 vaccine (Vero cell)

Arm 2: Flu Quadrivalent

EXPERIMENTAL

Study Arms 2 will have two groups: group 1 - HIV-uninfected receiving Flu Quadrivalent; group 2 - HIV-infected receiving Flu Quadrivalent. The Flu Quadrivalent is recommended as a single dose for adults, the second and the booster doses for Arm 2 will be placebo.

Biological: influenza season quadrivalent Influenza Vaccine (Flu Quadrivalent)

Arm 3: BBIBP-CorV and Flu Quadrivalent (Co-administration)

EXPERIMENTAL

Arm 3 will have 1 group - HIV-uninfected co-administration group receiving both study vaccines.

  • Provide written informed consent before any trial procedure.

You may not qualify if:

  • Pregnant, lactating, or with intention to become pregnant during the study.

Masking Details
The PI, study staff, and participants will be blinded as to receipt of study vaccine or comparator. The pharmacy staff preparing the vaccine syringes and the study nurse who is administering the vaccine will not be involved in the safety assessment of participants and will be instructed not to comment on the experimental agent to study staff. Enrollment numbers will be assigned sequentially by the study nurse/pharmacist upon confirmation of eligibility and enrollment into the study according to their Human Immunodeficiency Virus (HIV) stratification by the Investigator. All case report forms (CRFs) and source documents will be labeled with the enrollment number and study visit number. Personal identifying information linking the study number to an individual volunteer will not be captured on case report form (CRF) as study data.
