As COVID-19 vaccinations continue to be distributed, equity is vital to the process. Vaccination availability for individuals from minority groups is an important issue—partly because of longstanding inequitable access to quality care, and partly because of public sentiment, reflected in polls showing that Black Americans’ mistrust of health care and medical research may influence their feelings about getting vaccinated. Charles Senteio, a health informatics scholar focused on equity and one of MIT’s 2020-21 MLK Visiting Professors, has been conducting an ongoing study of this issue, along with David Rand, the Erwin H. Schell professor at the MIT Sloan School of Management. Senteio, Rand, and their interdisciplinary team have found that attitudes toward COVID-19 vaccines vary significantly within Black communities, and they contend that effective vaccine outreach should factor in these differences.
