Did you know "Vaccines were developed to protect people from dangerous and often fatal diseases. These diseases remain a threat. Vaccines are safe and effective protection. Vaccination in childhood prevents serious illness and lifelong disability from certain vaccine-preventable diseases (VPDs). People not vaccinated as children are vulnerable to VPDs and their consequences as adults." https://www.immunize.org/wp-content/uploads/catg.d/p4017.pdf
In the wealthiest country in the world to not protect your child like going backward, backward thinker reductionist going back to the 1950 where they let their kids die because many kids died pushes the need to do better not to go back to those days! No?
~~~~Overall, today is much safer than 1950. That’s probably no surprise to anyone who knows basic economic history. What’s particularly interesting is that safety gains are especially large for younger kids. The mortality rate for kids under 5 was almost five times greater in 1950, 3.7 times greater for kids 5-14, and 2.2 times greater for 15-24 year olds. https://www.econlib.org/archives/2009/08/modernity_as_a.html
~~~~In 1945, there were 12 Grecians suffering from polio. More than half the men, women, and children attacked by polio recovered with no enduring affects; 29% were left with a slight residual paralysis, 18% remained handicapped, and 3% died. It was most fatal to children under the age of 10, such as Ronald Gammeriello of North Greece Road who contracted polio when he was one and died from it at age 4. https://greecehistoricalsociety.org/tag/childrens-health-in-the-1950s
*Must note a practice in those days was to put the sick child with the not sick child so the non sick kid gets immunity maiming both possibly. Sickness causes harm. The point why it's said they let their children die!
Get your kid the vaccines!
