I know Amin PD has asked us to take vaccine discussion to the appropriate thread, but I feel that this is relevant. You say
but at least I am informed about vaccinations now and can make good decisions for us both in the future.
Can I use a single example from your post to show that you are not quite as informed as you believe. If you go to the following site
you will notice that the tell you diphtheria vaccine is actually an inactivated form of the diphtheria toxin. This causes you to produce antibodies to the toxin and not the bacterium. Naturally occurring, non-toxigenic diphtheroids, by definition do not produce toxin. Therefore I find it hard to see how these bacteria will confer resistance to diphtheria toxin.
The problem with diphtheria is that the toxin it produces (an iron-chelating siderophore) is only produced when iron availability is low and it inhibits protein synthesis all round the body, producing pathological effects in the heart, kidney, gut etc. By targetting the toxin the vaccine ensures maximal protection from these effects. The genes for toxin production are carried on a bacteriophage which the toxigenic strains carry. There are non-toxigenic strains of Corynebacterium diphtheriae. these confer no resistance to the disease whatsoever.
I'm not trying to have a go at you, just to demonstrate that you can make yourself even better informed and make the right decisions for the right reasons.
I've only used a small part of your post as an example. If you would like to discuss this further, I'll meet you in the vaccine thread.
