I read the link again and I lean to #3, but will read it again. If and when a vaccine is available, people who take vaccines should do this one too. I have not taken any vaccines for 40 yrs probably and no flu in all those years and what little flu I might have been close to I've nipped with Oscillo homeopathy med. I rely on my own natural immune system which I feed very well.

They will be adding the preservatives they do to vaccines and we can probably count on aluminum being one of them grrrrrrrrrrrrr
