Persistent drop in confidence following US recommended pause of Ad26.COV2.S vaccine administration.

The Janssen COVID-19 vaccine came to market in February 2021 as the first non-mRNA and first single-dose formula approved for use in the US. In April 2021, a temporary pause was recommended for the vaccine after the discovery of rare but serious post-vaccination side-effects. We fielded a large-scale nationally representative survey (n = 401,398) on individual confidence in each of the COVID-19 vaccine formulas available in the US before, during, and after this pause. We find widespread loss of confidence in the Janssen vaccine across gender, age, and other demographics, which persisted over time and after lifting of the halt. Despite this drop, overall reasons for remaining unvaccinated were stable and there was a concurrent minor bump in confidence towards other vaccine formulas. This contrast between the persistent reduction in confidence in the Janssen vaccine and the apparent maintenance of the broader campaign's integrity, highlights the complex dynamics and downstream effects of the pause.

Identifying COVID-19 Vaccine Deserts and Ways to Reduce Them: A Digital Tool to Support Public Health Decision-Making.

A private-academic partnership built the Vaccine Equity Planner (VEP) to help decision-makers improve geographic access to COVID-19 vaccinations across the United States by identifying vaccine deserts and facilities that could fill those deserts. The VEP presented complex, updated data in an intuitive form during a rapidly changing pandemic situation. The persistence of vaccine deserts in every state as COVID-19 booster recommendations develop suggests that vaccine delivery can be improved. Underresourced public health systems benefit from tools providing real-time, accurate, actionable data. (Am J Public Health. 2023;113(4):363-367. https://doi.org/10.2105/AJPH.2022.307198).

COVID-19 vaccine delivery: an opportunity to set up systems for the future.

The race to develop safe and effective SARS-COV-2 vaccines has moved with unprecedented speed. There are now multiple promising candidates seeking emergency use authorization from the United States Food and Drug Administration and a host of candidates positioned for approval worldwide. Attention has now turned to allocation, distribution and verification of these vaccines, yet this focus exposes that the underlying infrastructure for global delivery and monitoring is threadbare and unevenly distributed. This presents both a barrier and an opportunity to deploy sustainable infrastructure. Major global stakeholders must convene quickly, collaborate, and collectively invest in global standards, legal models, common vocabularies and interoperable biometric-supported digital health technologies. As the COVID-19 vaccine effort scales, governments, private sector and NGOs have the chance to place lasting resources needed for equitable and effective delivery that can pay dividends into the future.

Equitable allocation of COVID-19 vaccines in the United States.

Many vaccine rationing guidelines urge planners to recognize, and ideally reduce, inequities. In the United States, allocation frameworks are determined by each of the Centers for Disease Control and Prevention's 64 jurisdictions (50 states, the District of Columbia, five cities and eight territories). In this study, we analyzed vaccine allocation plans published by 8 November 2020, tracking updates through to 30 March 2021. We evaluated whether jurisdictions adopted proposals to reduce inequity using disadvantage indices and related place-based measures. By 30 March 2021, 14 jurisdictions had prioritized specific zip codes in combination with metrics such as COVID-19 incidence, and 37 jurisdictions (including 34 states) had adopted disadvantage indices, compared to 19 jurisdictions in November 2020. Uptake of indices doubled from 7 to 14 among the jurisdictions with the largest shares of disadvantaged communities. Five applications were distinguished: (1) prioritizing disadvantaged groups through increased shares of vaccines or vaccination appointments; (2) defining priority groups or areas; (3) tailoring outreach and communication; (4) planning the location of dispensing sites; and (5) monitoring receipt. To ensure that equity features centrally in allocation plans, policymakers at the federal, state and local levels should universalize the uptake of disadvantage indices and related place-based measures.

COVID-19 Vaccine To Vaccination: Why Leaders Must Invest In Delivery Strategies Now.

Worldwide, leaders are implementing nonpharmaceutical interventions to slow transmission of the novel coronavirus while pursuing vaccines that confer immunity to severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection. In this article we describe lessons learned from past pandemics and vaccine campaigns about the path to successful vaccine delivery. The historical record suggests that to have a widely immunized population, leaders must invest in evidence-based vaccine delivery strategies that generate demand, allocate and distribute vaccines, and verify coverage. To generate demand, there must be an understanding of the roots of vaccine hesitancy, involvement of trusted sources of authority in advocacy for vaccination, and commitment to longitudinal engagement with communities. To allocate vaccines, qualified organizations and expert coalitions must be allowed to determine evidence-based vaccination approaches and generate the political will to ensure the cooperation of local and national governments. To distribute vaccines, the people and organizations with expertise in manufacturing, supply chains, and last-mile distribution must be positioned to direct efforts. To verify vaccine coverage, vaccination tracking systems that are portable, interoperable, and secure must be identified. Lessons of past pandemics suggest that nations should invest in evidence-informed strategies to ensure that coronavirus disease 2019 (COVID-19) vaccines protect individuals, suppress transmission, and minimize disruption to health services and livelihoods.
