I do not think $RVVTF would have made it this far, if they did not have something, since the Canadian equivalent of the USA BARDA federal funding and loans kept flowing into RVVTF.
There are stocks like RVVTF that I held on to, that eventually went to Nasdaq, and made huge moves, that looked nearly dead before the stadium lights went on.... I was Buying Opxs at these prices in 2014 and it is close to $14 this month. TGTX was another. Went from .001 to $50
Bullish
