Vaccine ingredients getting into the bloodstream

[Guest guest]

Someone had a point the other day that got me thinking. I was talking about not

wanting to

inject vaccine ingredients into my babies and he pointed out that some of that

stuff we eat

(take aluminum, for example) and gets into the bloodstream that way. Sounds

right to me -

not sure if it's 100% accurate. I know vaccines aren't supposed to be injected

directly into

the bloodstream but who's to say that a vein/artery is never hit accidentally?

Is there indeed

a similarity here?
