Title of Project: Development of methods for the evaluation of the effectiveness of COVID-19 vaccines and other vaccines and drugs for potentially pandemic infectious diseases in the VA system 2. Scope of Work: The contractor shall provide all resources necessary to accomplish the deliverables described in this Performance Work Statement (PWS), except as may otherwise be specified. The scope of work includes providing methodological and statistical guidance on the development of methodologies to model vaccine effectiveness. Additionally, the contractor shall communicate any sort of challenges that arise that may warrant input from the study team. The statistician(s) at Acumen who work on this project will be invited to attend project calls with study team members and FDA sponsors. Ad-hoc meetings or consultations will be scheduled as needed. 3. Background: The COVID-19 pandemic alerted the regulatory and public health community about the need to obtain highly reliable data on the real-world effectiveness of vaccines and other regulated products during the pandemic in near real time, including among high risk and frail populations, while accounting for unmeasured confounding and other sources of bias. Multiple vaccines and drugs for COVID-19 and other pandemic viruses have been authorized or licensed by the United States Food and Drug Administration (FDA). In preparation for a future pandemic, which could be a coronavirus, influenza or other infection, we need to develop reliable and unbiased methods for the real-world evaluation of the effectiveness of vaccines and drugs to prevent and treat any potentially pandemic infectious disease. Evaluating methods for the timely and reliable assessment of the effectiveness and comparable effectiveness of vaccines in the large and diverse VHA population would provide data generalizable to Veterans along with other high-risk groups in the U.S. and abroad. Identifying the most effective vaccines and strategies may inform and enhance care of Veterans in the future, particularly given the high proportion of comorbidities among Veterans and that individuals with more comorbidities may be at greater risk of severe outcomes of infection. Given this, the study aims to develop methodologies for estimating vaccine effectiveness and monitoring waning of effectiveness over time. 4. Performance Period: The contractor shall complete the work required under this PWS within the time frames stated in each individual task order, unless otherwise directed by the Contracting Officer (CO). The contract shall have a 5-year term. GENERAL REQUIREMENTS 1. For every task, the contractor shall identify in writing all necessary subtasks (if any), associated costs by task, along with associated milestone dates. The contractor's subtask structure shall be submitted with the technical proposal and detailed work plan. 2. All written deliverables shall be phrased in layperson language. Statistical and other technical terminology shall not be used without providing a glossary of terms. A final written report detailing progress, problems encountered and solved, and other observations shall be submitted within 30 days of task order expiration. 3. Where a deliverable is required in draft form, the VA will complete their review of the draft deliverable within 14 calendar days from the date of receipt. The contractor shall have 14 calendar days to deliver the final version from date of receipt of the Government s comments. SPECIFIC MANDATORY TASKS AND ASSOCIATED DELIVERABLES Description of Tasks and Associated Deliverables: The contractor shall provide the specific deliverables described below within the performance period stated on individual task orders. Integral to the tasks outlined below will be effective project coordination on the part of the contractor and reliable communication between the contractor and the White River Junction VA PI (Dr. Caroline Korves) and study team. The contractor will engage in day-to-day project management as necessary to ensure that methods development occurs according to protocol and timeline. The contractor shall provide updates during project calls at least monthly along with a document summarizing developments to date and assist in the preparation of written methods and results for manuscripts for peer-review. Communication between the contractor and the team will be ongoing and will include phone calls and email correspondence as needed. If the contractor encounters difficulties with methods development, they will consult as needed with the study team. If the contractor anticipates they will be unable to complete a task within the associated timeframe, they shall communicate this to the team so that all parties can make adjustments to the timeline and associated deliverables as needed. Task 1:Â Work closely with the team to develop methodology for modeling time and offset terms in models of waning vaccine effectiveness To expand the use of self-controlled methods for assessing vaccine effectiveness and waning of immunity, it is essential that different approaches for modeling time be considered as these different approaches may better approximate actual waning of immunity. Furthermore, self-controlled methods must account for time-varying confounders, such as changes in viral circulation over the course of an influenza season. These changes are captured in offset terms in models. Additional work on the validation of offset terms currently included self-controlled methods for assessing waning immunity are necessary to ensure that time-varying confounders are adequately adjusted. The contractor is responsible for working on this vital component of the study with the study team. They shall complete this portion of the study by working collaboratively with the aforementioned parties. The contractor will have no access to any patient-level data from VHA; they will utilize datasets of hypothetical patients with disease onset dates to develop methodology. The study team will collaborate with the contractor on the development of the methodology; The study team will apply methodology to VHA data and only share results from VHA data with the contractor in aggregate, summary form. Deliverable:Â The contractor shall work collaboratively with previously mentioned parties to develop new approaches to modeling time in waning of vaccine effectiveness models and to validate offset terms in models. The contractor will provide the team with a written summary of methodology and accompanying SAS code. [Months 01-02] Task 2: Implementation of new methodologies for evaluation of influenza vaccine effectiveness and waning of immunity Following the above described work on modeling time and the offset term, the study s aim is to evaluate influenza vaccine effectiveness and estimate waning of immunity. Two influenza seasons will be analyzed. The contractor will critically review results that the study team produce and provide guidance for refinement in methodology given specific characteristics of each season and distribution of vaccine types within each season. The contractor shall conduct reviews of study results that the study team share and provide guidance on ways to cross-validate finding; guidance may include written methodology and SAS code. Deliverable: The contractor shall provide feedback during at least monthly project calls as well as brief reports. After analyses are complete, the contractor will assist in writing data analysis methods and results in manuscripts and conference presentations. [Months 03-08] EVALUATED OPTIONAL TASKS AND ASSOCIATED DELIVERABLES As work progresses, there may be other areas of exploration discovered. In this event a project statement will be drafted by VA and a budget for the additional work may be requested from the contractor. Issuance of additional task orders is based upon the availability of funding. SCHEDULE FOR DELIVERABLES 1. If for any reason any deliverable cannot be completed within the scheduled time frame, the contractor is required to explain why in writing to the CO, including a firm commitment of when the work shall be completed.
