Amazing how Mymetics collaboration results with ETHERNA never came to light; active clinical trial (TriMix) per link in your post. Vague, one sentence closure without detail per prior 10K.
It must be sitting with the Sanofi findings that have never been published.
An HIV virosome-based vaccine has been prepared from influenza viruses by adsorbing some HIV-1 virulence antigens, such as gp41 and p1 peptides, and by including the adjuvant 3M-052, a thermostable adjuvant that increases virosome membrane rigidity [121,122].
In another study, a thermostable HIV-1 virosomal vaccine was composed of an influenza-enveloped virosome with HA, NA, lecithin, cephalin, and other phospholipids, with the addition of 3M-052, Toll-like receptor (TLR7/8) and the sugar trehalose [116].
Studies have shown that a recombinant HPV16 E7 influenza virosome induced strong CTL responses and prevented the development of an HPV16+ transformed cancer.
