Assessing New York City's COVID-19 Vaccine Rollout Strategy: A Case for Risk-Informed Distribution

Area of Science:

• Public Health
• Epidemiology
• Health Policy

Background:

• The early COVID-19 vaccine rollout faced challenges in reaching all populations equitably.
• Eligibility policies significantly influenced vaccine accessibility and uptake.

Purpose of the Study:

• To assess the impact of COVID-19 vaccine eligibility policies on vaccination coverage and mortality rates in New York City.
• To identify disparities in vaccine access based on socioeconomic status and age.

Main Methods:

• Retrospective ecological study using linked Census Bureau and NYC Health administrative data.
• Analysis of vaccination coverage and COVID-19 mortality rates across Modified Zip Code Tabulation Areas (MODZCTAs).
• Ordinary Least Squares (OLS) regression to model total mortality rates based on income, age demographics, and vaccination rates.

Main Results:

• Low-income areas with high proportions of older adults had significantly lower vaccination coverage (mean 52.8%) compared to wealthier areas (mean 74.6%).
• These lower-coverage areas experienced higher COVID-19 mortality rates over the subsequent year.
• Younger individuals in high-income areas accessed vaccines early, sometimes ahead of eligibility.

Conclusions:

• The implemented vaccine rollout strategy, based on initial eligibility policies, was suboptimal in reducing overall mortality.
• Policymakers must consider local contexts and prioritize high-risk populations for equitable vaccine distribution.
• A strategy focusing on vulnerable, low-income, older populations in New York City could have potentially lowered overall mortality.
