"Besides breastfeeding, there is no other childhood intervention that has as much medical evidence supporting its safety and efficacy in preventing debilitating diseases than routine immunizations. Great article below outlining a well done study on the bottom line on vaccines. Bottom line is, vaccines are one of the greatest public health discoveries of modern humanity and we choose not to use them at our own peril.
As for components of vaccines, they are in the vaccines that are used in the studies and still they show VERY low rates of adverse reactions. Pentacel (DTAp-IPV-Hib), one of the first vaccines given, does contain formaldehye, but in trace amounts.
Aluminum Phosphate (adjuvant)
Tris (hydroxymethyl) aminomethane
BSA, formaldehyde, glutaraldehyde, neomycin and polymyxin B are present in trace amounts.
Should you be worried about that? No. The ingredients are in such small amounts they are of no concern. Besides, the attached document shows that formaldehyde occurs in high levels naturally in some foods.
Then there is Prevnar, pneumococcal vaccine for babies. Contains the following, besides the vaccine components of course.
sodium chloride, polysorbate 80, succinic acid and aluminum as aluminum phosphate adjuvant.
Meningitec: Meningitis vaccine
Water for Injection
Priorix-Tetra (measles, mumps, rubella, varicella)
Amino acids for injection
Water for injection
Fluviral (influenza vaccine)
disodium hydrogen phosphate heptahydrate
potassium dihydrogen phosphate
water for injection
That covers the main routine immunizations for kids.
And in case those ingredients still scare the hell out of you, consider the ingredient list from:

And of course through wizardry allowed by Health Canada, food companies do not have to list the components of flavors, only to say that it may contain artificial flavor. Well, here is what is in strawberry flavor:
