I don't know. I am hoping to get people with this knowledge to give us some insights on this new information.
(Cytokine Storm:) Of course, flu vaccines are usually effective at preventing the flu during its peak season. But they are no guarantee, especially when flu strains mutate after the vaccine has been manufactured. Therefore, researchers are pursuing other methods of preventing the Cytokine storm by bioengineering a drug that could slow the snowball effect of antibodies. They hope to force the cytokines to recirculate in the bloodstream, rather than pool in the lungs. Experts predict that a major influenza pandemic could kill millions of people worldwide as it has done in centuries past.
Evidently, a reliable anti-cytokine treatment is not here, but efforts are being focused towards that end.
"hemophagocytosis" is the rough equivalent here of "storm". H5N1 is the name for this virus.
It sounds really nasty. Really nasty.
