Traditional media constituted the majority of these 20 websites, along with other social media and governmental sources. We identified markers of inauthentic propagation for some of these links. Conclusions: The topic of vaccination was prevalent in tweets about COVID-19 early in the pandemic. Sharing websites was a common communication strategy, and its “bursty” pattern and inauthentic propagation strategies pose challenges for health promotion efforts. Future studies should consider cross-platform use in dissemination of health information and in counteracting misinformation. %M 34665760 %R 10.2196/29127 %U //www.mybigtv.com/2021/12/e29127 %U https://doi.org/10.2196/29127 %U http://www.ncbi.nlm.nih.gov/pubmed/34665760
