Using social media to understand the vaccine debate in China
A team of United States-based researchers observed an example of this in 2018 related to the Changchun Changsheng Biotechnology vaccine incident in China.
The researchers found:
“The World Health Organization identified vaccine hesitancy as one of their top 10 challenges of 2019. When combined with virulent illnesses, such as COVID-19 or influenza, small changes in vaccination rates could spell the difference between smaller, contained outbreaks and a worldwide pandemic. Governments and public health agencies around the world need to prioritize health communication efforts. Even the safest and most effective vaccine is useless if people refuse to take it, said David Broniatowski, associate professor of engineering management and systems engineering at the George Washington University.
The new study, “Chinese Social Media Suggest Decreased Vaccine Acceptance in China: An Observational Study on Weibo Following the 2018 Changchun Changsheng Vaccine Incident,” highlights the dangers of public perception of even a single vaccine safety incident, according to the researchers.
The team also believes the possible emergence of vaccine opposition in China is a potential cause for concern, especially considering the density of several large Chinese population centers.
2018 VACCINE INCIDENT IN CHINA
In July 2018, Chinese government inspectors determined that Changchun Changsheng Biotechnology, a prominent manufacturer of vaccines in China, had violated national regulations and standards when producing 250,000 rabies vaccine doses. The violation might have undermined the effectiveness of the involved vaccines. News began slowly escalating on Chinese social media platforms not long after the incident.
