And remember your boosters as adults!
Currently there is a measles outbreak in the U.S. The outbreak is clustered into communities where parents choose not to get their children vaccinated. Vaccination works primarily on herd immunity. In rare cases, someone who is vaccinated CAN get the disease. It is not 100% perfect, but it is far far better than the results of NOT vaccinating. Measles can kill, cause permanent damage and put those who, for some medical reason, get a vaccination. Vaccination, while not binary, vastly, by a factor of millions, reduces disease. It works, but only when we realize it is a social responsibility if we want to participate in society. Many preventable diseases are contagious prior to symptoms arising and are airborne, simply suggesting isolation is not even close to being as effective as vaccination. Not getting vaccinated puts others at risk.
It's also not just measles. It's mumps, rubella, whooping cough, polio, influenza, tetanus, shingles and other infectious viruses vaccinations prevents.
Vaccination doesn't cause autism. It's not a government eugenics program. It's not mind control or drug experimentation, it's not against God's will, prayers doesn't cure disease.
