Justification:
These sources are all scholarly or otherwise trustworthy. The KFF is a non-profit organization that provides data and analysis on health policy issues. The other two sources are articles published in peer-reviewed journals, which means that they have been reviewed by other experts in the field.
These sources help me to understand the problem of racial and ethnic disparities in COVID-19 contraction rate and access to the vaccine in several ways. First, they provide data on the extent of the disparities. For example, the KFF report found that as of July 11, 2022, Black people were less likely than White people to have received at least one dose of the COVID-19 vaccine (59% vs. 87%).
Second, these sources help to explain the factors that contribute to the disparities. For example, the article in Preventing Chronic Disease found that socioeconomic factors, such as income and education, mediate the relationship between race and ethnicity and COVID-19 vaccination coverage.
Third, these sources suggest potential strategies for addressing the disparities. For example, the article in JAMA Network Open found that increasing access to vaccination sites in underserved communities and providing culturally relevant education about the vaccine may help to reduce disparities in vaccination coverage.
Overall, these sources provide valuable information on the problem of racial and ethnic disparities in COVID-19 contraction rate and access to the vaccine. They help me to understand the extent of the disparities, the factors that contribute to them, and potential strategies for addressing them.
