I thought Ennis's experiment was double blinded, and was also carried out in four different labs (kind of like a simultaneous replication, although I'm sure that doesn't count as scientific evidence of replication). Also, I've read that the Horizon experiment was very different from Ennis's and therefore does not invalidate her research. See http://www.homeopathic.com/articles/media/2020_enn is.php which purports to be an email from Ennis to the Horizon researchers listing discrepencies. If this is authentic (and I have no way of knowing if it is or isn't) it would also seem that the Horizon experiment could never demonstrate an effect as the basophils would have been "killed off". A more balanced report of the Horizon results is included in the New Scientist here: http://www.newscientist.com/article/mg18624940.300 .html
Overall... I think we still need to await better science for more definitive answers one way or the other.
