Estimated Post Date: Sept. 1, 2021.

The purpose of this notice of funding opportunity (NOFO) is to support research to evaluate the long-term effectiveness of COVID-19 vaccines against symptomatic and asymptomatic infections through long-term follow-up of vaccinated individuals (adults and children) and to assess immune response metrics, symptoms, and the development of asymptomatic infection/viral shedding. Studies should be adequately powered to generate product- and variant-specific vaccine effectiveness estimates and to assess risk factors for vaccine breakthrough, including demographic, immunologic, and virologic risk factors, where possible.

CDC solicitations are usually limited to one application per institution.
