this is my take on VXLafter reading online posts, some people are saying that this company could be bankrupt, if that were the case, why would the WHO put them on this list, which btw i can't confirm.
if they are on that list, they could have something, as for a pump and dump, i don't believe this is the case, it wouldn't look good on the WHO.
i'm not touching too many stocks right now, but i do like bio's. remember, you put some of your money into a stock, the circuit breakers shut down, and the next day, if you are lucky, your stock hasn't suffered to much of a loss overnight. why take the chance.
this is all just a guess, do your due diligence and glta
