That “worst health” label includes a ranking of 34th in the world with infant mortality.
In other words, the USA has the 34th worst infant survival with its highest rate of vaccinations. Some are directly from multiple vaccinations administered.
But the USA leads the world in infant vaccinations, those administered during the first year after their births – 26 vaccinations during that time.
The only vaccination I recall receiving during early childhood, circa 1948, was the smallpox vaccine, the one that left a circle of shallow pockmarks on the upper arm, a non-ink tattoo that proved you had received that vaccine.
Months later there was the booster shot which gave me a vacation of several days away from my first grade teacher while sitting out the chicken pox.
During Naval training the mass vaccination high pressure hand held gun that replaced syringes and needles was tried on us with the polio shot.
I wound up with a vacation in the base infirmary with an extended period of the flu. Between those two, there may have been a tetanus shot or two.
From the Healthy Home Economist:
-In1950, there were 3 childhood vaccines typically given when a child entered school.
-In 1983, there were 10 recommended vaccines by the age of 6 years old (24 doses, 7 injections, 4 oral doses for polio).
-In 2010, the CDC vax schedule totaled 68 doses with more than half given by the time a child was only a year and a half old.
-In 2016, the schedule has increased to 74 doses by age 17 with 53 injections and 3 oral doses of rotavirus.
