Foods that contain MSG typically also contain high levels of sodium that can cause headaches and other health effects so it's still worth keeping a eye out for, as MSG being in a food is a sign that some of the other ingredients might be harmful in high quantities.
Over/improper use of antibiotics have led to a significant increase in multi-resistant bacterial strains such as MRSA, one of the most common and difficult medical complications to treat or recover from.
If the extra protein (egg protein) doesn't hurt anyone, why would the cdc and mayo clinic, all explicitly discourage exposure of patients with severe egg allergies to the MMR, flu, or yellow fever vaccines?
They have an ALLERGY. By your logic, should gluten be condemned and banned because a few people are allergic to it?? The CDC and Mayo Clinic are doing their jobs correctly by warning patients with allergies and not making a blanket policy for everyone because of the special cases.
Thimerosol contains trace amounts of mercury in it, however fish eating populations consume more mercury from the fish than they do in a dose of the vaccine. There are no credible articles that show a link between thimerosol exposure and autism
Thimerosol is 50% mercury by weight, more than an insignificant proportion. Additionally, some vaccines such as the multi dose presentation of Afluria contain significant amounts of mercury. Tolerable levels are 30 micrograms/day, this one contains 24.5 micrograms per dose.
Since high levels of thimerosol, and thus mercury, are found in some flu vaccines, provided his cousin (or the driver) were of small enough body mass, significant effects such as partial loss of vision or even mood swings and mental disturbances may occur.
It's possible, or it could have been a million other things. Making that assumption is just outlandish. Show me a few peer-reviewed, well-controlled studies with large random samples that indicate a strong correlation between vaccines and car crashes, then we have a discussion.
