Population Health Research Brief Series

Despite various efforts by governments, businesses, and health care providers, a large share of the U.S. population remains resistant to getting the COVID-19 vaccine. Understanding why individuals refuse the vaccine is important for tailoring interventions to improve vaccination rates.

This brief examines age differences in reasons reported for not getting the vaccine. Concerns about possible side effects are the most common among every age group, but other reported reasons, including lack of trust in the vaccine and the government vary by age group. Findings suggest that tackling COVID-19 misinformation is critical to increase vaccination rates in the United States.
