Philippine COVID-19 Vaccination Through an Infodemiological Lens: A One-year Web-based Search Volume Analysis From 2020 to 2021
Main Article Content
Abstract
This infodemiological research explored the online public interest in COVID-19 vaccine registration and its asso- ciation with Filipinos’ interest in its side effects, efficacy, alcohol interaction, safety, and dangerousness. It utilized Google Trends to gather search volumes in the Philippines from December 2020 to November 2021. After describing the queries and search volumes, multiple linear regression was done. The results showed that the Filipino public was more interested in the safety of COVID-19 vaccines than their danger. Interest in its efficacy, interaction, and side effects initially increased but decreased over time. Vaccine registration initially dropped but later increased in November 2021, perhaps due to a national holiday for public vaccination. Strikingly, interest in COVID-19 vaccine registration was only associated with its safety and had no relationship with interaction, efficacy, and side effects. Therefore, reliable online information on the safety of COVID-19 vaccines is crucial to improving public interest in COVID-19 vaccination.
