If YOU mixed mercury, aluminum phosphate, ammonium sulfate, formaldehyde and viruses and injected it into someone, you’d kill the because you have no pharmacological experience.
If someone in a lab mixed those together, knew how they work, and medically assessed and peer reviewed evidence and strict guidelines to follow to create a safe and effective product, then YES.
We've eradicated diseases like polio, and stopped the spread of deadly epidemics. People like you who don't vaccinate your child not only threaten your own child, but anyone he's in contact with. A vaccination does not bestow invulnerability, merely resistance. By not vaccinating, your child would be at a far higher risk for lovely things like the flu, or whooping cough, or etc. Even worse, those your sick child is in contact with will be exposed as well, which risks their health. Ultimately I can't convince you. I'm not a doctor. But please, listen to YOUR doctor. Keeping you and your kids safe is his JOB.
