Why can’t the current one understand the importance of vaccines??
On February 23, 1954, a group of children from Arsenal Elementary School in Pittsburgh, Pennsylvania, receive the first injections of the new polio vaccine developed by Dr. Jonas Salk. Thanks to the vaccine, by the 21st century polio cases were reduced by 99 percent worldwide.
Though not as devastating as the plague or influenza, poliomyelitis was a highly contagious disease that emerged in terrifying outbreaks and seemed impossible to stop. Attacking the nerve cells and sometimes the central nervous system, polio caused muscle deterioration, paralysis and even death. Even as medicine vastly improved in the first half of the 20th century in the Western world, polio still struck, affecting mostly children but sometimes adults as well. The most famous victim of a 1921 outbreak in America was future President Franklin Delano Roosevelt, then a young politician. The disease spread quickly, leaving his legs permanently paralyzed.
