Potential Risk of Overlooking Biased Reporting of Vaccination against Novel Coronavirus Disease 2019: Lessons from Japan's Experience with the Human Papillomavirus Vaccine

抄録

Vaccination is a crucial and evidence-based measure against novel coronavirus disease 2019 (COVID-19) implemented worldwide, including in Japan, where more than 67% of the population has received more than three doses of vaccination as of February 2023. Although some common adverse reactions of the vaccine, such as fever and arm pain, have been reported, serious adverse reactions resulting in death, such as myocarditis and Guillain-Barré syndrome, are rare. However, the biased reporting of the adverse reactions of the COVID-19 vaccine in the Japanese media has recently become more frequent, which is similar to the past biased reporting on the human papillomavirus (HPV) vaccine. Previously, the media's biased reporting on the HPV vaccine caused public mistrust in vaccines, leading to a drop in vaccination rates in Japan. Thus, overlooking the sensational reporting of the media on the current COVID-19 vaccine may potentially influence people's health behavior and awareness in the long run. Actually, experts worldwide agree that the COVID-19 vaccine is safe, and the media reports are inconsistent with the observations. Thus, it is necessary to urge the media to release accurate information to prevent tragedies caused by biased reporting. Moreover, it is essential to correct misinformation in reporting, disseminate accurate information from media outlets, such as Internet news and video-sharing sites, and promote awareness among people to support the vaccination rate against COVID-19.
