At least 5 companies have launched Phase III clinical trials of COVID-19 vaccines, the final step before seeking approval from the U.S. Food and Drug Administration (FDA). According to NIAID director Anthony Fauci, vaccines may be widely available in the U.S. by spring 2021 if these trials are successful. 

But should these vaccines become available, will Americans accept them? Between July 10 and July 26, we surveyed 19,058 adults in all 50 U.S. states and the District of Columbia. We asked about the likelihood that they would seek vaccination for themselves, and for their children. We also asked about the factors that would influence their decision making. 

We find that, overall, 66% of adults would be somewhat or extremely likely to vaccinate themselves; 66% would be somewhat or extremely likely to vaccinate their children. These rates vary markedly between states, as shown on the figure below.
