Parents unwilling to let their children have vaccines - other than for proven medical reasons - should read an old newspaper from pre-vaccine days. Then they could read reports like one about a measles outbreak in New York state in April 1946. More than 7,500 children came down with measles in 13 days! That's what children's diseases were like in pre-vaccine years.
Those parents should talk to a polio survivor who spent part of his or her childhood in an iron lung, or a volunteer who spent afternoons reading to youngsters stuck in those machines, or a senior citizen whose friend spent his adult years in a wheelchair due to polio.
There were 57,000 cases of polio in the U.S. in 1952, mostly in children. More than 3,000 died, and more than 21,000 had mild to disabling paralysis.
Let's not go back to those years.
