A polio vaccine designed to be incapable of evolving the ability to cause disease in humans has shown promise in a Phase I clinical trial. Why not just give the vaccine to large numbers of children and However, the first two polio vaccine trials in humans in 1935 had disastrous results. small scale trials. The New York Times later reported that he hadn’t wanted to make the radio announcement at all.

People dressed as Superman and Wonder Woman visit with kids waiting . Yes. [8], Brodie was head of one of two separate teams that developed polio vaccines and reported their results at the annual meeting of the American Public Health Association in November 1935. Brodie presented his results afterwards, but the feelings of the researchers were already unfavorable before he started because of Kolmer's report. Throughout the 20th century polio was a global health threat that the public had no way to prevent. In 1938 the FDA was given regulatory authority over experimental drugs.

In April 1955 more than 200 000 children in five Western and mid-Western USA states received a polio vaccine in which the process of inactivating the live virus proved to be defective. viruses. And a year later, a radio broadcaster warned his audience in that the vaccine “may be a killer” because, he said, public health services had found that in 70 percent of the batches they tested the virus hadn’t been inactivated at all (officials and Salk himself quickly stepped up to counter that report).

But the campaign for a cure was finally beginning to produce promising developments. Over the decade it took to uncover this story, Rebecca became enmeshed in the lives of the Lacks family—especially Henrietta’s daughter Deborah.

As a medical breakthrough unfolded in the early 1950s, newspapers filled pages with debates over vaccine science and anecdotes . [13] But some experts felt Brodie's vaccine deserved further study; the case against it was inconclusive and too hastily drawn.

Pfizer and BioNTech’s COVID-19 vaccine trials, a manufacturing error in the vaccine itself. .
