This study used an explanatory design and voluntary sampling method with a total of 201 respondents from generation X, Y, and Z. This study showed that there was a significant difference in term of knowledge, perception, and motivation between generations. More than half of respondents had a moderate level of knowledge related to vaccination. Moreover, respondents of generation X and generation Y were more likely to have poor perception regarding COVID-19 vaccination and lack motivation to receive the vaccine. Meanwhile, generation Z recorded a moderate level of perception and motivation regarding vaccination. The results of the regression test showed that number of dependents, vaccination status, and perceptions related to vaccination had a significant influence on motivation to receive COVID-19 vaccination.
