Two papers authored by Regenstrief research scientists and published in the U.S. Centers for Disease Control and Prevention’s Morbidity and Mortality Weekly Report (MMWR) achieved a Top Ten Altimetric Attention Score on the CDC’s website.

Regenstrief Director of Public Health Informatics Brian Dixon, PhD, MPA, and Regenstrief Vice President of Data and Analytics Shaun Grannis, M.D., M.S., were co-authors on “Waning Effectiveness 2-dose and 3-dose mRNA Vaccines Against COVID-19-Associated Emergency Department and Urgent Care Encounters and Hospitalizations Among Adults During Periods of Delta and Omicron Variant Predominance — VISION Network, 10 States, August 2021–January 2022,” published February 18. 

The second article is “Effectiveness of a Third Dose of mRNA Vaccines Against COVID-19–Associated Emergency Department and Urgent Care Encounters and Hospitalizations Among Adults During Periods of Delta and Omicron Variant Predominance — VISION Network, 10 States, August 2021–January 2022,” published January 28. The Altmetric Attention score measures the engagement articles received on social media and blogs over the past three months. 

Drs. Grannis and Dixon have contributed to six MMRW papers over the last several months.
