This week we look at how scientists have fared in the search for a COVID-19 vaccine.
We speak to Helen Yang, senior director of global strategy and business development at Sinovac Biotech. She tells us how her company has been fighting the coronavirus. Yang explains why it's been difficult to trial a vaccine in China and why her company has been testing them in Brazil, Turkey and Indonesia instead [02:20].
We also speak to Paul Offit, head of the Vaccine Education Center at the Children's Hospital of Philadelphia. Offit outlines the timeline attached to finding a new vaccine and explains why we shouldn’t be concerned if there are temporary setbacks in testing [09:00].
Finally, we are joined by Jerome Kim, director-general of the International Vaccines Institute in Seoul. He spoke to us earlier in March, and he was optimistic about the chances of finding a cure for COVID-19. Find out if he still remains hopeful [15:01].
