Perhaps one of the more controversial topics and scientific milestones in the past century, vaccines have changed the landscape of modern medicine as the world knows it. Through vaccines has come the eradication of smallpox, saving more than 5 million lives a year. In 1952, Jonas Salk not only invented a vaccine to cure Polio, but offered to the public for free. Because of vaccines humans have become resistant to some of what were once considered the deadliest diseases in the world, effectively raising the average life expectancy by more than 30 years in the past century.
Giving life to the hope of curing diseases that once devastated populations, vaccines have saved lives and prevented unnecessary death and illness. Yet, some question the integrity of vaccine ingredients and what potential effects they could have on children. In 1998 a fraudulent medical study was published in the British medical journal The Lancet, providing a link between the Measles, Mumps and Rubella (MMR) vaccine and Autism. Despite the researcher and study's loss of scientific credibility, some parents hold the idea the connection still exists. Still, what do scientists today hope to accomplish with future vaccines?
