Everyone is fucking retarded.

Antivaxxers and big pharma.
Vaccines are a combination product.
You should test INDIVIDUAL ingredients, starting on lab rats.
You think Thimerisol is bad? Test JUST Thimerisol on mice and rats, then monkeys, then humans if it was deemed safe on animals.
Do the same thing with aluminum adjuvants.
Aluminum and thimerisol have the most attention.

Now if there is a specific concern about immune responses to human specific pathogens, e.g. causing an increased incidence of allergies, or if you're worried HPV viral DNA could be a carcinogen, that requires more thorough testing of the active vaccine.
