Cant understand why people are still advocating so strongly for flu shots. Still no good effectiveness, and chances of risk. Please please please dont get the multi strain flu shot as it contains Mercury which isnt safe in any amount in the blood. It’s totally a choice, a gamble. Definitely not clear cut that “it works”, or “it’s safe”. Make your choice and don’t blame others who choose to take vitamins c and d daily instead. Flu comes from a vitamin d deficiency (no sun around)
