Factors associated with humoral immune response in older adults who received egg-free influenza vaccine. (PubMed, Vaccine) - "Overall pre-vaccination seropositivity was high and just over half of the cohort seroconverted to ≥ 1 vaccine antigen. Antibody responses were highest among participants with lower pre-vaccination titers. Among older adults with high pre-existing antibody titers, approaches to improve immune responses are needed."
