A Researcher from UNC Chapel Hill (Dr. Illona Jaspers) submitted a talk at an AAAS conference in Washington this week. I don't know whether her research has been published or if she is simply providing preliminary results. In either case, her conclusion is that e-cigs can suppress immune function just as much as cigarettes and probably even more so. This is in agreement with a different line of research being done at UC Davis where researchers there have published essentially the same results (e-cig vapor caused MSRA to attack cells more violently than those not exposed). The difference in this new research from that done at UC Davis is they sampled specific genes for immune suppressive effects as opposed to merely setting loose a bacteria. They sampled cells from humans who vaped, smoked and those who were non-smokers. They found that vapers had more immune suppressive effects than smokers.

Quote from the abstract of the presentation:

Our data confirm that smoking cigarettes causes suppression of several key immune genes in the nasal mucosa. E-cig users showed the same changes in immune genes as cigarette smokers. However, e-cig users also demonstrated suppression of several additional immune genes, suggesting even broader suppressive effects on respiratory mucosal immune responses as compared to cigarette smokers.

An article on the AAAS website that goes into a bit more detail.
