Brief summary
The goal is to evaluate the in-depth immunogenicity analysis (including B-cell and T-cell response) of coadministration of a omicron-containing COVID-19 vaccine and influenza vaccine among healthy adults during 2023-24 season.
Detailed description
This was an open-label, randomized clinical trial conducted at the International St. Mary's Hospital in Incheon, South Korea. This study included two study groups: Concomitant administration of omicron containing messenger ribonucleic acid (mRNA) COVID-19 booster and quadrivalent influenza vaccination (QIV) and separate administration of influenza vaccination followed by mRNA booster ≥4 weeks later * immunogenicity analysis : Blood was drawn at baseline and follow-up visit 4 weeks, 3 months, 6 months, 10-12 months after immunization(For the COVID-19 vaccine, additional blood sampling will be conducted one week after vaccination). * safety analysis : At 7 days after each vaccine dose, the participants were requested to record the occurrence, severity of solicited adverse events (AEs) through a standardized electronic questionnaire. Participants were also asked to record any unsolicited AEs during the 28 days after vaccination.
Interventions
The COVID-19 vaccine approved for use in the 2023-2024 season
inactivated vaccine containing 15μg hemagglutinin antigen/strain in each 0.5-mL dose, containing four influenza vaccine strains from the 2023-2024 northern hemisphere season

Eligibility
Inclusion criteria
* who agreed to receive both booster COVID-19 vaccine and influenza vaccine * individuals who have received the COVID-19 vaccine three or more times and have passed at least 3 months after the last vaccination * individuals with a history of a single SARS-CoV-2 infection during the Omicron outbreak period (January 2022-February 2023)
Exclusion criteria
* individuals with a contraindication to any of the vaccine compounds * individuals with a history of influenza infection within the past 6 months
