What Ingredients are in Vaccines?

Did you know that August is National Immunization Awareness Month (NIAM)? We've discussed our stance on vaccines before (you can read that post here). But today we're raising awareness about some of the preservatives that are used in vaccines and their potentially harmful side effects. As a pet owner, it's your right to not only choose whether or not to vaccinate your animals, but also to know what exactly goes into vaccines.

Did you know that August is National Immunization Awareness Month (NIAM)? We've discussed our stance on vaccines before (you can read that post here). But today we're raising awareness about some of the preservatives that are used in vaccines and their potentially harmful side effects. As a pet owner, it's your right to not only choose whether or not to vaccinate your animals, but also to know what exactly goes into vaccines.

Thimerosal (Mercury)

Thimerosal is a preservative that has been used in some vaccines since the 1930s, when the Eli Lilly Company first introduced it. It is 49.6 percent mercury by weight and is metabolized or degraded into ethylmercury and thiosalicylate. It has been removed from most pediatric vaccines. It has an affinity for the brain, gut, liver, bone marrow, and kidneys. Side effects of thimerosal include:

  • Even the smallest amounts can cause nerve damage
  • Symptoms of mercury toxicity (similar to those of autism)
  • Chronic exposure leads to decreased weight gain, decreased offspring survival, changes sperm production, severe mental retardation, motor coordination impairment, nervous system effects, liver effects, lung effects, kidney effects, and numbness in extremities
