Misinformation, Disinformation, and Vaccine Hesitancy in the Asia Pacific

What's the role of misinformation and disinformation in government? How much will they affect the vaccine implementation efficiency? CAPRI explores the varying experiences of vaccine hesitancy and the role of misinformation and disinformation in shaping government and civil society initiatives within the Asia Pacific region.

The COVID-19 pandemic magnified many governance challenges that predated the health crisis. From the necessity of swift responses against an unknown virus to the development of economic relief packages for supporting affected families and businesses, governments were confronted with amplified challenges to health, economic, and social resilience. Promoting vaccination, a long-standing challenge, became a critical testing ground during the COVID-19 pandemic, revealing the dynamics of how health information—both true and false—spreads and how the media landscape can shape health behavior.

Misinformation and disinformation reduce people’s confidence in vaccines. Recent experiences from the Asia-Pacific region in vaccine rollout have also highlighted the importance of cultural values, personal privacy, and communication in the design and implementation of public health policy. As this health emergency wanes and future crises loom on the horizon, the issue of vaccine hesitancy becomes increasingly crucial, amplified by the ever-expanding array of information and media channels. How can governments understand public attitudes toward vaccines and leverage communication strategies to protect population health? With distinctive cultural, political, and social systems, Asia-Pacific societies can offer compelling lessons for the world in navigating misinformation and disinformation to promote public health.

To this effect, CAPRI has been developing the first two reports in this series on Japan and Taiwan, which both have unique cultural, historical, and political contexts but could offer insights and best practices for the region.

Taiwan spent 2020 and the first months of 2021 largely free of COVID-19, thanks to strict border controls and nonpharmaceutical measures that eliminated community spread of the disease. In May 2021, local cases began to increase, and the government implemented tighter restrictions on movement and social life. At this time, only limited numbers of the AstraZeneca vaccine were available in Taiwan, and demand for them increased rapidly, creating an environment of uncertainty in which misinformation and disinformation could thrive.

Throughout the pandemic, both Taiwan’s government and civil society dedicated considerable attention to reducing the spread of misinformation and disinformation related to COVID-19. From May 20 to July 27, 2021, the Central Epidemic Command Center held an additional press conference every morning to address misconceptions about the pandemic and vaccines. Furthermore, Taiwan’s Ministry of Health and Welfare and Centers for Disease Control established clarification sections on their websites to help the public verify the accuracy of claims about COVID-19 and the vaccines. Taiwan’s government has also partnered with social media platforms, such as Google, Facebook, and LINE, to combat COVID-19 misinformation.

Taiwan’s civil society boasts robust fact-checking organizations, including the Taiwan FactCheck Center, Cofacts, and MyGoPen, which have worked closely with the government. In February 2020, Taiwan enacted the “Special Act on COVID-19 Prevention, Relief, and Restoration,” which included a provision penalizing the dissemination of rumors or misinformation about COVID-19. However, determining what constitutes a rumor or misinformation is not clear cut.

Although factors such as age, gender, level of trust in the government, and education level affect vaccine hesitancy in Taiwan, the information landscape during the pandemic contributed to people’s attitudes toward the COVID-19 vaccines, especially when their supplies were limited. The discussions on COVID-19 vaccines were politicized based on speculations that Mainland Chinese agents were spreading misinformation online and perceptions that Taiwan’s government was promoting its domestically developed vaccine prematurely. Given this experience during the pandemic and the robust ecosystem of civil society organizations researching misinformation, Taiwan can establish best practices for health literacy education and science communication to prepare for future health emergencies.

Vaccine hesitancy in Japan before the COVID-19 pandemic is well documented due to its unique history with various vaccines, in which misinformation plays a role. For example, early in the development of vaccines for polio and cholera, contaminated doses and improper administration resulted in people contracting the diseases, contributing to a persistent belief that vaccines can give people the diseases they protect against. In addition, extensive media coverage of adverse effects in young women who received the human papillomavirus (HPV) vaccine led to widespread wariness of adverse effects. Although the reports were based on anecdotal evidence that was later debunked, the HPV vaccination rate in Japan remains low. In both cases, misinformation about vaccines was based on true events, highlighting that collective memories are difficult to overcome.

Despite this history, vaccine hesitancy has decreased in Japan over time, including during the COVID-19 pandemic. Although a substantial portion of Japan’s population did not initially plan to get a COVID-19 vaccine, by May 2023, approximately 83% had received at least two doses, comparable to other high-income Asian countries. People who changed their minds to get vaccinated tended to perceive the benefits of vaccination, recognize the safety of the COVID-19 vaccines and the actual risks of the adverse effects, and acknowledge that vaccination is effective in preventing viral spread. In Japan’s cultural and political context, while government messaging and scientific communication have effectively encouraged COVID-19 vaccination, social connections and forging a social norm of vaccination have been key to increasing vaccine uptake in hesitant groups.

Misinformation remains a major concern, not least because of the role of social media in the information landscape. Studies in Japan have found that the more people use social media as a primary source of COVID-19 information, the more likely they are to be vaccine hesitant. In fact, the use of social media as a primary information source has been linked to people who originally intended to get vaccinated becoming more hesitant. Japan’s government has taken steps to combat this misinformation, including providing accurate information on its own websites, encouraging citizens to consult their doctors about vaccination, and debunking false claims that vaccinations are linked to infertility. Going forward, the effectiveness of these interventions in the Japanese context can be evaluated to identify best practices for other societies.
