The shot? H1N1? If so, keep in mind that the 'shot' is really the same as every other year's, as well as this year's, seasonal shot, just a different strain of flu. This year's seasonal chemical makeup is the same as last year's, just a different flu strain. H1N1 is similar, the same. If you can get it, get it. I will be getting mine as soon as it is available to me. Already had the seasonal back in August.
