Andrew Wakefield

Do vaccines cause autism? Medical experts say no, but we can thank Wakefield for introducing the doubt that won’t die in many parents’ minds. In 1998, the gastroenterologist at Royal Free Hospital in London published a study describing a connection between the measles-mumps-rubella (MMR) vaccine and autism, after he found evidence of these viruses, presumably from the shot, in the guts of a dozen autistic children, eight of whom developed autism-like symptoms days after receiving their vaccination.
Other scientists could not replicate Wakefield’s findings, nor verify a link between the vaccine and autism. In 2010, the journal that published his paper retracted it, and its editors noted that “it was utterly clear, without any ambiguity at all, that the statements in the paper were utterly false.” Later that year, the General Medical Council in the U.K. revoked Wakefield’s medical license, citing ethical concerns over how he recruited the patients in the study as well as his failure to disclose that he was a paid consultant to attorneys representing parents who believed their children had been harmed by vaccines.
The final shoe dropped a year later, when another prestigious medical journal concluded that his research was also fraudulent, after evidence that some of the timelines of the children’s symptoms were misrepresented.
Wakefield maintains his innocence, and penned a book defending his work and his continued belief in a connection between vaccines and autism. Infectious disease experts and pediatricians, meanwhile, routinely confront conflicted parents who question the safety of vaccines, despite immunization’s long-standing record of successfully controlling childhood diseases with relatively few side effects.
Woo Suk Hwang

It’s not often that scientists achieve rock star status, but that’s what Hwang enjoyed when, seemingly out of nowhere, the Seoul National University professor of veterinary medicine catapulted South Korea to the top of the science hierarchy with his 2004 success in cloning human cells and making human embryonic stem cells.
Or at least that’s what he and everyone else in the world thought he had done. It was the first time anyone had taken a human cell, inserted it into a donor egg, and coaxed it to grow, in theory into a clone of the original cell. He followed that stunning announcement a year later with another first — using the same process to generate embryonic stem cells from patients with spinal cord injury and diabetes, opening the possibility that patients might benefit from stem cell therapies to cure these and other diseases.
That same year, however, anonymous tips raised questions about images depicting the stem cell lines in one of the papers, and a university and government investigation revealed that the stem cells did not come from the cells as Hwang claimed, but from IVF embryos. Hwang said was not aware of the fraud, which he maintained was perpetrated by members of his lab, but was stripped of his position at the university and banned from conducting stem cell research in Korea. He is reportedly seeking investors to fund his research outside of the country.
