The CDC Vaccine schedule does not look so bad until you count the number of ACTUAL DOSES
(shown in red next to each vaccine acronym):
Recommended CDC Schedule Infants and Children (In Utero to 6 years old)
Recommended CDC Schedule Preteens and Teens (7 to 18 years old)
Recommended CDC Schedule Adult (19+ years old)
The number of vaccines has grown exponentially since 1986, when the Vaccine manufacturers no longer had liability of their products.
