I would probably start the search with these two papers:
Jackson, K. J. L., Liu, Y., Roskin, K. M., Glanville, J., Hoh, R. a, Seo, K., … Boyd, S. D. (2014). Human Responses to Influenza Vaccination Show Seroconversion Signatures and Convergent Antibody Rearrangements. Cell Host & Microbe, 105–114. http://doi.org/10.1016/j.chom.2014.05.013
Moody, M. A., Zhang, R., Walter, E. B., Woods, C. W., Ginsburg, G. S., McClain, M. T., … Haynes, B. F. (2011). H3N2 influenza infection elicits more cross-reactive and less clonally expanded anti-hemagglutinin antibodies than influenza vaccination. PLoS ONE, 6(10). http://doi.org/10.1371/journal.pone.0025797
I don't see the mAbs sequences in the data repo or supplemental materials, but I didn't look very hard.
