You don't need to know what's in a vaccine, All you need to know is the doctors inject it into your bloodstream, And it keeps you from getting whatever disease the vaccine is required to keep away.
The only risk you might have is being allergic to whatever is in the vaccine, Overdosing the vaccine or taking the wrong vaccine.
Vaccinations are good because they allow your body to build immunity and/or resistance to diseases. Certain diseases that were a major problem decades ago are no longer an issue due to vaccines; examples include smallpox, Measles, Polio, Etc. Why do we think people are encouraged to get flu shots every winter? Vaccines do not cause autism.
We are told by medical professionals vaccines are healthy, But we are never told what is in vaccines. The CDC provides the list, In it's entirety, Of all ingredients in vaccines. Formaldehyde, Aluminium, MSG, A wide rage of ethanol's, Human fetal cells, Etc. There has been extensive evidence since the 50's that ethanol's cause long term health effects, Such as cancer, Intestinal damages, And brain disorders. The amount of mercury in vaccines is enough to cause damage in infants, Toddlers and even adults! Whoever says vaccines do not cause autism are not informed correctly. They are rather fed the information the news force feeds down people's throats instead of doing actual research. I would much rather my child fight off infection from their own anti-bodies and immune systems, Rather than get injected with a whole bunch of unnecessary "healthy" vaccines. Vaccines have been studied multiple times, And if you take the time to watch/learn about the actual studies instead of the watered down, "family friendly" documentaries that get pushed out like wildfire, You would probably be more aware of what you are pumping your children with. Smallpox, Measles, Polio have been eradicated for years, But yet, The government tells you that you need to pump your body full of shit in order to prevent them? ! Are you kidding me.
