Each dose contains 50 mcg of thimerosol, which is an extremely dangerous level of mercury for the body. [...] If that isn’t punishment enough, each dose also contains residual amounts of ovalbumin, formaldehyde (known neurotoxin), and sodium deoxycholate from the manufacturing process. Can anyone say "GROSS"?
