I agree that the whole fascination(obsession) with removing bacteria from the household can weaken ones defences.
I like a clean home, some people go OTT. Constant jabs for this and that also weakens the immune system.
You are actually contradicting yourself here. Indeed too clean a house means that the body is not exposed to germs so it is unable to mount a defence against them - so "weakening" the immune system.
BUT vaccinations work just that way too. they present a challenge to the body in a similar way that the actual virus would, so that the body is able to design itself a defence strategy for that virus if it should ever come up against it.
In that way they STRENGTHEN the immune system, they provoke it to INCREASE its armoury - they don't weaken it.
The vaccine should not cause disease as they are manufactured using either killed virus which cannot replicate in the body, but has the right coating so that the immune system designs the right anti-bodies. or the vaccine virus is altered in some way that stops it being able to invade or replicate or some other such thing that stop the disease taking hold.
However it is true that people can often feel unwell after being vaccinated. This may be the response they feel when their immune system is being kicked into gear and responding to the vaccine - i.e. making the right kind of antibodies that would be needed should they be actually infected. The vaccine needs to be effective enough to stimulate the immune system properly, and so often we feel ill when we get a jab.
Proper trials etc are essential though, to make sure that the vaccine version of the virus really can't cause that disease (or another disease altogether).
hope that made sense...
