Read that little tidbit earlier today - as I hold a small (and quite red at present) batch of HEB shares & pay attention to what they PR.
Ampligen 'could' be effective against Zika - it certainly appeared to be against Ebola in some tests done at USAMRIID late 2014 - very early 2015.
HEB would have the added advantage that they don't need to do any new development on Ampligen. They just have to find a partner with the ability to do some preclinical testing of it on Zika models.
