COVID-19 vaccine uptake in a predominantly minoritized cohort hospitalized during the early pandemic in New York City.

BACKGROUND

Minoritized communities in the United States have had higher COVID-19 mortality and lower vaccine uptake. The influence of previous SARS-CoV-2 infection, initial disease severity, and persistent symptoms on COVID-19 vaccine uptake in Black and Latinx communities has not been examined.

OBJECTIVE

To investigate whether initial COVID-19 severity, persistent symptoms, and other correlates affected vaccine uptake in a predominantly minoritized cohort hospitalized for COVID-19 during the early pandemic in New York City.

DESIGN

In this historical cohort study, we abstracted electronic health record data on demographics, comorbidities, hospital oxygen requirements, symptoms at 3 and 6 months post-admission, COVID-19 vaccinations through November 2022, and influenza vaccinations during the 2018-2019 through 2021-2022 seasons. Unadjusted and adjusted odds ratios were estimated through logistic regression analyses of correlates of COVID-19 vaccination, on-time vaccination, and boosting.

PARTICIPANTS

Survivors among the first 1186 adult patients hospitalized for COVID-19 between March 1 and April 8, 2020 at a large quaternary care medical center in Northern Manhattan.

MAIN MEASURES

Uptake of at least one COVID-19 vaccine dose, uptake of at least one booster, and on-time vaccination.

KEY RESULTS

The 890 surviving individuals were predominantly Latinx (54%) and Non-Hispanic Black (15%). Most had one or more comorbidities (67%), and received at least one COVID-19 vaccine dose (78%). Among those vaccinated, 57% received at least one booster, and 31% delayed vaccination. 67% experienced persistent symptoms. Multiple logistic regression showed no association between vaccine uptake and disease severity or symptom persistence. However, older age and influenza vaccination during the COVID-19 era were associated with increased vaccination, booster uptake, and on-time vaccination.

CONCLUSIONS

Pinpointing drivers of vaccine uptake and hesitancy is critical to increasing and sustaining COVID-19 vaccination as the field transitions to annual boosters. The association between influenza vaccination and increased vaccine uptake suggests that bundling vaccines for adults may be an effective delivery strategy.
