The most recent study I know of is conducted by clearstream working closely with utah vapers. The study has completed and is now in the process of full doctoral review so the summary is no longer published at that page. The short version is that second hand vapor contains no harmful chemicals and no nicotine. Really the only possible irritants that I can think of are the trace amounts of flavor.

* If e-cigarettes were in immediate risk to public health they would have been banned immediately and recalled after the FDA study.
* Re:Nicotrol Inhaler: “the small amount of nicotine emitted into the environment is well below levels associated with adverse effects”
* Main ingredient (PG) used in the liquid is also used in asthma inhalers and to carry medicine to the lungs of lung transplant patients.

Conclusions
The above experiment, within the limits of the observed
parameters, has underlined that e-smoking
does not produce detectable amounts of toxic and carcinogenic
substances in the air of an enclosed space.

In conclusion, our study does not indicate any harmful effect of nicotine when given in its pure form by inhalation

Once exhaled, the e-cig vapor was found to contain miniscule amount of nicotine and flavoring. The primary compound detected in the exhaled vapor was propylene glycol, which is present in many of the foods we eat has been deemed safe by the FDA. Despite being the first of its kind, this study proves what proponents of the electronic cigarette industry have been saying for years: second-hand vapor is not harmful.

The e-cigarette does not create side-stream smoke.
Exhaled breath after e-smoking contains even less nicotine per puff, as much of the nicotine inhaled is absorbed. Similarly, propylene glycol is largely absorbed and little is exhaled.
No harm found in e-cigarette mist

CONCLUSIONS:
For all byproducts measured, electronic cigarettes produce very small exposures relative to tobacco cigarettes. The study indicates no apparent risk to human health from e-cigarette emissions based on the compounds analyzed
