I view squalene as a pretty evil additive. Sutherlandia OPC (oleander), curcumin, blackseed oil (Nigella sativa) and magnesium should all help modulate the immune system and help against possible squalene problems - though nothing helps so much as avoiding it.
Although I recommended cilantro and cilantro for the flu vaccine and not the flu, I have not seen any indication that they would increase a cytokine storm response by the actual flu itself.
When it comes to the flu, any flu, keeping plenty of good Colloidal Silver on hand is by far the best idea as far as I am concerned. And, as indicated earlier, I also think it is a must to have on hand for those who choose or perhaps are forced to take the vaccines.
