Ok, I didn't want to hijack the other flu shot thread so......
I came across this meta-analysis from the Lancet, referred to by the NaturalNews website.
NaturalNews link here: http://www.naturalnews.com/033998_influenza_vaccines_effectiveness.html
And the Lancet meta-analysis: http://www.thelancet.com/journals/laninf/article/PIIS1473-3099%2811%2970295-X/abstract - hope resources are available to get the review at your health place.
It took me a minute to see which direction the article was coming from.....
Ok.....go to figure 2. Section A.
Check out the treatment group: 221 individuals out of 18,797 who recieved a flu shot got the flu. That's 1.2%.
Now check out the control group: 357 individuals out of 13,095 who (technically) recieved a placebo got the flu. That's 2.7%.
The difference is 1.5%.
So if you get the flu vaccine, it would prevent 1.5 individuals out of a 100 strong population from getting the flu.
Wow, that's a great deal.
