You don't become a battle ready soldier by playing Call of Duty®... and your favorite pro football team won't start you at quarterback just because you've mastered their offense in Madden Football®. The simulated world of video games is no replacement for REAL WORLD experience. So how can you expect an artificial shot to make you REALLY immune to the flu?
Your immune system is pretty smart. Every time your body is exposed to germs or viruses in the environment, your immune system detects the invader and mounts an appropriate defense. Maybe your immune system creates a fever to make it difficult for the invader to spread, or a general malaise to shift energy away from muscle activity to white blood cell production. Whatever the response, your immune system innately learns and builds on its expertise - growing its ever expanding protective skills from REAL WORLD EXPERIENCE. That's the right way to build natural, acquired immunity.
Germs and viruses don't naturally come armed in formaldehyde, mercury, glycol, aluminum adjuvants, gelatins, foreign egg proteins and antibiotics. Those 'video game' bugs don't exist - yet that's the extra insult your immune system has to contend with when you allow an artificial flu shot into your veins... and there's nothing REAL WORLD about that.
Never run out of something to say...
