Zinc acetate does not appear to work.
Howdy pufferfish:
The study you quote also seems to say that zinc gluconate lozenges don't work either. It states, "Neither formulation" (zinc acetate nor zinc gluconate) "had an effect on the duration or severity of natural cold symptoms".

There is a legend that oral zinc tablets don't work, but there has never been a study...
Howdy John:
Here are a couple more studies that call into question the effectiveness of zinc lozenges:

and
http://www.ncbi.nlm.nih.gov:80/entr...eve&db=PubMed&list_uids=3298301&dopt=Abstract
Several other studies indicate that zinc lozenges do reduce the duration and/or severity of cold symptoms, but there does seem to be some legitimate concern about just how effective zinc lozenges might be. It's possible that similar concerns will crop up over time as zinc gels are looked at by additional researchers.
HTH,
