Abstract and Introduction


We assessed coronavirus disease vaccination and intent and knowledge, attitudes, and beliefs among essential workers during March–June 2021. Coverage was 67%; 18% reported no intent to get vaccinated. Primary concerns were potential side effects, safety, and lack of trust in vaccines, highlighting the importance of increasing vaccine confidence in this population.


Essential workers, who conduct a range of operations and services to ensure the continuity and viability of critical infrastructure functions, have more coronavirus disease (COVID-19) exposures and experience greater risk for severe illness and death than do nonessential workers.[1–4] In December 2020, the US Advisory Committee on Immunization Practices issued recommendations prioritizing healthcare personnel (HCP), nonhealthcare frontline essential workers, and other essential workers for COVID-19 vaccination[5] (Appendix, Previous findings indicate that <50% of essential workers intended to get vaccinated: 37.1% in September 2020 and 49.1% in December 2020.[6,7] Assessing vaccination coverage and intent among essential workers, who continue to face increased risk because of their public-facing roles can help tailor messages and strategies to increase vaccination uptake and confidence among this high-risk group. We analyzed data from surveys to assess COVID-19 vaccine coverage and intent and knowledge, attitudes, and beliefs (KABs) among essential workers.
