The children get pediatric doses, which will be unaffected by a run on the adult version. However, I think that most of the cost is related to administering the shot, so I doubt that vials would be sold for future use.
I had about 48 hours of audio hallucinations on and off with the bug I have.The third,"bad" day,I was even having visual hallucinations.
I had a slight fever if any and have never used illicit drugs.Another FReeper had hallucinations back in the 50s,I believe with flu.
Have you heard of this before without a bad fever?
