简要总结
This pilot study will investigate B-cell responses following vaccination with live, attenuated influenza vaccine (LAIV) in healthy children 2 years of age from blood samples taken at designated time points before and after vaccination.
详细描述
This is an exploratory study to determine the peripheral antibody secreting cell response during Days 5-13 after immunization with live, attenuated influenza vaccine (LAIV).
Investigators hoped to enroll 27 healthy children, 2 years of age who had not had any prior LAIV or trivalent inactivated vaccine (TIV) within the past 2 years. Due to low enrollment, the study was halted. Due to the limited number of samples, no analysis was performed.
