I am a scientist. I have done the research that the CDC makes it nearly impossible to do. The conclusion I drew from the literature was that unless I should become "high risk," it doesn't provide a benefit that, to me, is worth the risk of not knowing what effect it will have on my body (long term). In my opinion, it's a cash grab by the pharma companies. With nearly every other vaccine, upon introduction of the vaccine, the numbers of infections per year dropped. Show me that for the flu & maybe I'll reconsider.
