The advent of H7N9, in early 2013, is of concern for a number of reasons, including its capability to infect humans, the etiology of infection is unclear, and that, broadly the human population does not have pre-existing immunity to the H7 subtype. Earlier sequence analyses of H7N9 hemagglutinin (HA) point to amino acid changes that predicted human receptor binding and impinge on the antigenic characteristics of the HA. Herein we report that the H7N9 HA shows limited binding to human receptors; however, should a single amino acid mutation occur, this would result in structural changes within the receptor binding site that allow for extensive binding to human receptors present in upper respiratory tract. Furthermore, a subset of the H7N9 HA sequences demarcating coevolving amino acids appear to be in the antigenic regions of H7, which in turn could impact effectiveness of the current WHO recommended pre-pandemic H7 vaccines.
