People are traveling across China in the hopes of getting an experimental Covid-19 vaccine shot

When Anny Ku heard that there were coronavirus vaccines on offer in Yiwu, a city in China's eastern Zhejiang province, she traveled more than 600 miles (965 kilometers) for a chance to get the shot. Ku worked in Chile for more than 20 years as an importer and exporter, but she returned to her home in southern China earlier this year after the coronavirus pandemic worsened and a large number of cases appeared in South America. There had been no official announcement that a vaccine was available in Yiwu -- just a series of articles in local media -- but Ku believed she needed the shot in order to leave China and get back to her job overseas. 'If one has (the vaccine), it's much safer to leave the country,' she said
