With the problem of disinformation becoming more apparent, one of the current topics for disinformation campaigns is the COVID-19 vaccine, which has broad implications for public health. This research was conducted to investigate a possible connection between the amount of vaccination-related disinformation and the willingness among the Dutch population to get vaccinated. The contribution of this research is 1) developing a tool-supported approach to identify words and bigrams used in alternative news outlet, 2) classifying disinformation-related vocabulary, 3) applying the approach that relates disinformation and vaccination willingness in the context of the COVID pandemic, highlighting its strengths and limitations. We conceptualised vaccination disinformation, expressed it in certain’trigger terms’ and plotted the popularity of those terms amongst Dutch Internet users over time, using Google Trends and Twitter data. Using a linear regression model, we combined this with vaccination willingness studies of June through December of 2020 to investigate a possible correlation. Our results, while not statistically significant, did point towards a negative relationship between disinformation spread and willingness to vaccinate. Further research, utilizing similar approach and additional available information on vaccination willingness, may provide more insight on disinformation spread and vaccination willingness across the world. © 2021, IFIP International Federation for Information Processing.
