“Does the flu vaccine work the same for everyone? No. While the flu vaccine is the single best way to prevent the flu, protection can vary widely depending on who is being vaccinated (in addition to how well matched the flu vaccine is with circulating viruses). In general, the flu vaccine works best among healthy adults and older children. Some older people and people with certain chronic illnesses might develop less immunity than healthy children and adults after vaccination. However, even for these people, the flu vaccine still may provide some protection.” — CDC
So… could it possibly be (… just saying) that the reason the “flu vaccine works best among healthy adults” (and other healthy people) is that they are HEALTHY, their immune system is strong… and thus they would be unlikely to catch the flu in the first place? Could it be that the flu vaccine, in fact, is NOT “the single best way to prevent the flu”, but rather that building up your immune system is?
Could it be the flu shot is completely irrelevant, and that people are paying good money to inject mercury, formaldehyde, gelatin, and other toxins into their bodies for no good reason at all? I mean, if you really want to further ruin your health (particularly for the elderly and chronically ill), do you really need to pay for it?
