About this study

Official title: Different Significance of Reactogenicity in Immunogenicity and Inflammatory Response by New COVID-19 Vaccine Platforms: BNT162b2 mRNA Versus ChAdOx1 nCoV19 Vaccine

Analysis of humoral antibody and cytokine kinetics after vaccination with either BNT162b2 or ChAdOx1 nCoV-19 vaccine and factors influencing the vaccine immunogenicity

Read the detailed description

There is a different aspect of reactogenicity between BNT162b2 and ChAdOx1 nCoV-19 vaccine. Both new platform vaccines were concerned if they would elicit more significant local or systemic reactogenicity compared to the conventional vaccines. Previous studies had reported that immune cells such as mast cells and macrophages are activated just after vaccination, and release proinflammatory cytokines such as interleukin (IL)-6 and tumor necrosis factor (TNF)-α. The post-vaccination kinetics of inflammatory cytokines would be variable by each vaccine platform, and might be associated with reactogenicity. It is an interesting issue to be investigated whether the reactogenicity following newly developed BNT162b2 and ChAdOx1 would be associated with immunogenicity and inflammatory response or not. To better clarify these uncertainties, we evaluated the change of antibody response between BNT162b2 and ChAdOx1 over three months post-vaccination, in relation to the kinetics of inflammatory cytokines and reactogenicity.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • either BNT162b2 or ChAdOx1 vaccineBiological

    Either BNT162b2 or ChAdOx1 was assigned to each participant by the Korean governmental policy, not allowing personal choice. Sixty participants were vaccinated with two doses of the ChAdOx1 (AstraZeneca) at 12-week intervals, and the remaining sixty were immunized with the BNT162b2 (Pfizer-BioNTech) vaccine at 3-week interval.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Immunoglobulin G (IgG) anti-S antibodies

    measured using the Elecsys® Anti-SARS-CoV-2 S assay (Roche, Rotkreuz, Switzerland)

    Measured: At 3 weeks after the first-dose vaccination (T1)

  2. Immunoglobulin G (IgG) anti-S antibodies

    measured using the Elecsys® Anti-SARS-CoV-2 S assay (Roche, Rotkreuz, Switzerland)

    Measured: At 3 weeks after the second-dose vaccination (T2)

  3. Neutralizing antibodies

    Reduction in plaque count of 50% (PRNT50) was calculated for the median neutralizing titer (ND50) using the Spearman-Karber formula

    Measured: At 3 weeks after the first-dose vaccination (T1)

  4. Neutralizing antibodies

    Reduction in plaque count of 50% (PRNT50) was calculated for the median neutralizing titer (ND50) using the Spearman-Karber formula

    Measured: At 3 weeks after the second-dose vaccination (T2)

  5. IL-6, TNF-α, and IL-1ß

    measured by flexible customized bead-based multiplex panels for Luminex assays (Human Premixed Multi-Analyte Kit, R\&D Systems Inc., Minneapolis, MN, USA).

    Measured: At 3 days after the first dose

  6. IL-6, TNF-α, and IL-1ß

    measured by flexible customized bead-based multiplex panels for Luminex assays (Human Premixed Multi-Analyte Kit, R\&D Systems Inc., Minneapolis, MN, USA).

    Measured: At 3 days after the second-dose

  7. reactogenicity after vaccination

    Local erythema/swelling was regarded as positive sign if larger than 2.5 cm in diameter. Systemic adverse events were graded as follows: grade 0, no systemic adverse event; grade 1, any adverse event that did not interfere with activity; grade 2, any adverse event that interfered with daily activity. Fever was classified as grade 1 (from 37.5℃ to 38.4℃) and grade 2 (>38.5℃). Systemic adverse events were classified into two ways: (i) the highest level of severity of any adverse event reported by the participants and (ii) with or without specific adverse event.

    Measured: Until post-vaccination day 7

Secondary outcomes (3)
  1. The correlation between humoral immune response and reactogenicity after vaccination

    The correlation between humoral immune response and reactogenicity after vaccination

    Measured: The correlation between reactogenicity after the first dose and immunogenicity at T1 (3 weeks after dose 1 prior to dose 2) and T2 (3 weeks after dose 2);the correlation between reactogenicity after vaccine dose 2 and immunogenicity at T2

  2. The correlation between cytokine response and reactogenicity after vaccination

    The correlation between cytokine response and reactogenicity after vaccination

    Measured: At 3 days after each dose

  3. Long-term immunogenicity: Immunoglobulin G (IgG) anti-S antibodies

    measured using the Elecsys® Anti-SARS-CoV-2 S assay (Roche, Rotkreuz, Switzerland)

    Measured: At 3 months after the second vaccination (T3)

Questions about this trial

What is this clinical trial studying?

An observational study of COVID-19 Vaccination and Inflammation, run by Korea University Guro Hospital at 3 sites in South Korea.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?
