Proper nutrition is incredibly important for a healthy immune system, normal healing, the list goes on and on... Unfortunately, the exact effectiveness (i.e. an actual number) of proper nutrition at preventing getting sick from the flu is incredibly hard to define or measure.

What if you have an auto immune issue and you eat correct.y?

[@patrickguenette1115]

Where does the WHO get the original virus strain? Do they come from samples taken from humans that have already been infected? I've always been curious about that and this video has not explained it.

[@patrickguenette1115]

And also how do they decide which strains to use in the vaccine? Is it based on current combined research from hospitals and clinics? I'm curious

[@ilovetech8341]

How do they isolate a few viruses, something that's 40 nanometers in size without a bunch of other crap in it from the centrifuge ?

[@Vocaloidict]

So the whole world uses one vaccine?

I’m trying to figure out how I just listened to 9 min. of INFORMATION, yet came away without any KNOWLEDGE.

[@The.Alabama.Woodsman]

2019 was nearly the effectiveness rate..... try below 50% and lower! For 50% or less my work is forcing me.... literally forcing me with the threat of my employment if I don't get a flu vaccine..... what ever happened to, "My body my choice?"

[@vallang4832]

Your rights are being violated.

Isn't proper nutrition MUCH more effective than shots? It works better for me.

[@feraacedia1825]

Ethan Glover No, proper nutrition does not get rid if measles, polio, meningitis, hepatitis, etc...

[@jeffp565]

Yes nutrition is much better for you... Don't get the shots. (Natural selection at work)
