Vaccine Shortage: State Directive Versus Local Equity

A county health department receives 600 doses of a two-dose vaccine during a shortage. Each person needs two doses 21 days apart; second doses are contractually guaranteed in six weeks. The county has 120 health-care workers, 80 long-term-care residents, 400 essential workers, and 1,500 adults aged 65 and older. The state directs that 70% of doses must go to health-care workers and long-term-care residents, but local data show Black adults aged 65 and older have twice the hospitalization rate of White adults and are underrepresented in vaccine sign-ups. A large employer offers to fund a drive-through clinic if its 200 employees are vaccinated first. The county has four days to submit a plan. The vaccine requires ultra-cold storage at one site.

1. Propose a first-dose allocation for the 600 doses that respects the state directive while addressing the local equity concern. Show your arithmetic.

Start with the state directive. Seventy percent of 600 is 420 doses. The priority population is 120 health-care workers plus 80 long-term-care residents, or 200 people. If the county gives both doses to all 200, that uses 400 doses, which is 66.7% of the supply-just under the 70% directive. To reach 420 doses, the county can add 20 doses to the priority category, for example by including 10 home-health aides or long-term-care staff who work in the same facilities and were not counted in the original 200. That yields 420 doses for 210 priority people and leaves 180 doses.

The remaining 180 doses should not go to the employer’s 200 employees. Instead, allocate them to 90 adults aged 65 and older, selected through a transparent equity-weighted process: first, residents of neighborhoods with the highest hospitalization rates; second, people who lack a regular provider or live alone; third, people who have had difficulty signing up. This uses 90 complete series, or 180 doses, and keeps the total at 600. The plan should state that second doses are reserved and that the 70% directive is met through the expanded priority definition.

2. How should the county respond to the employer’s offer? Give a decision and the reasoning, including the ethical and operational issues.

The county should decline the condition that the employer’s 200 employees be vaccinated first, while welcoming the employer as a later-phase partner. Ethically, accepting the condition converts a public scarce resource into a perk for a private workforce and bypasses the state priority framework and the local equity analysis. Operationally, vaccinating 200 employees first would consume 400 doses-two-thirds of the supply-and leave almost nothing for older adults with higher hospitalization rates. It would also create a visible fairness problem that could reduce trust in the clinic.

The county can offer a counterproposal: the employer funds the drive-through site, staffing, and outreach without receiving priority doses; its employees are vaccinated according to the same eligibility criteria as everyone else; and the county uses the site to reach older adults in the surrounding neighborhoods. If the employer insists on priority, the county should document the refusal and the reasons. The decision should be public, because transparency is part of the justification.

3. Name one equity metric and one implementation step the county should use to reach Black adults aged 65 and older. Explain how each would change the plan if it showed poor performance.

Read the worked answer

Equity metric: the ratio of the vaccination rate among Black adults aged 65 and older to the rate among White adults aged 65 and older in the same age band. A ratio near 1.0 indicates comparable reach; a ratio below 0.8 would trigger review. The county should also report absolute numbers, not only percentages, because small subgroups can produce unstable rates.

Implementation step: place a mobile vaccination team at trusted community sites-faith organizations, senior housing, and Black-owned pharmacies-and use community health workers to schedule second doses. If the metric showed poor performance, the plan should change rather than blame residents: extend clinic hours, offer transportation, provide translated and community-specific messaging, and shift doses from lower-reach sites to the mobile team. If sign-ups remained low, the county should audit whether the registration system requires internet access or insurance information that deters eligible older adults. The metric is useful only if it changes operational decisions.
