So what are the implications if someone gets a contaminated dose. The reason I ask is that my father got the vaccine and in about week, ended up with a bad bladder infection followed by pneumonia. He wondered if the vaccine had anything to do with it or if it was just coincidental.

Well, injecting bacteria and/or viruses into the muscle of the arm sounds pretty invasive and nasty.

There are a couple of issues, that concern me.

1) injecting organisms into the body is a dicey thing. That is why there are sterility requirements. In fact disturbed parents with Munchhausen's by Proxy disorder inject things into their kids creating infections. If injecting bacteria and/or viruses were a harmless thing, there would not be the strict rules for cleanliness and sterility for injectables!

2) The elderly typically have a slower immune response anyway, so giving vaccines, takes up the immune factors, leaving the body open to other infectious situations. Some may get Shingles, or a viral pneumonia. When I had my Shingles, which causes a cellulitis for me, I ended up with pneumonia 5 days later! This is because my system was fighting the Zoster virus and the pneumonia took an opportunity.

So when people say they got sick right after a vaccine, I do believe that this is what is happening. We have all sorts of organisms on us and in our bodies waiting for a chance to become virulent. Giving a vaccine, which uses up immune factors for a short time, opens that door.

If you look up the explanation for the complements (immune factors), you'll see low complement levels for 3 and 4 occur when there is an infection. I would think a vaccine would do the same thing.

Just a year ago or 2 after that flu season, it was published that the elderly did not even benefit from those vaccines. It was less that 10% developed antibodies. So now they have really made them STRONGER and I would think that would deplete people even worse! Everyone today either has had a reaction or knows someone who has developed serious illness after the flu shots.

One really has to apply a form of logic to understand these complex situations. Something that doctors do not do. They just look at numbers, and don't really study the vaccines in depth, or over time.

So one has to do this themselves. At least if you make your own informed decisions, you have only yourself to blame in the end if you get some unwanted result.
