A study of booster-dose influenza vaccination responses compared to standard-dose in lupus patients: an open labelled, randomized controlled study

Phase 2
Completed
Conditions
Immune responses to influenza vaccination in lupus patients receiving high and low immunosuppressive agent
lupus
high dose influenza vaccine
seroprotection
seroconversion
Registration Number
TCTR20230610003
Lead Sponsor
Mahidol university
Brief Summary

In conclusion, booster dose influenza vaccination may increase seroconversion in some strains (H1N1 and B/Victoria), especially in patients who received high levels of immunosuppression. However, there were no clinical differences in the incidence of influenza infection between the SD and BD regimens. Further studies on a larger scale are necessary.
