Preterm birth is a global health priority. Using a progestogen during high-risk pregnancy could reduce preterm birth and adverse neonatal outcomes. ⋯ Patient-Centered Outcomes Research Institute.

The research and development (R&D) ecosystem has evolved over the past decade to include pandemic infectious diseases, building on experience from multiple recent outbreaks. Outcomes of this evolution have been particularly evident during the COVID-19 pandemic with accelerated development of vaccines and monoclonal antibodies, as well as novel clinical trial designs. These products were developed, trialled, manufactured, and authorised for use in several countries within a year of the pandemic's onset. ⋯ In addition, important changes are required for multiple aspects of enabling sciences and product development. For each of these elements we identify priorities for improved and faster functionality. There will be no better time than now to seriously address these needs, however difficult, as the ravages of COVID-19 continue to accelerate with devastating health, social, and economic consequences for the entire community of nations.

Observational Study
Assessment of protection against reinfection with SARS-CoV-2 among 4 million PCR-tested individuals in Denmark in 2020: a population-level observational study.
The degree to which infection with SARS-CoV-2 confers protection towards subsequent reinfection is not well described. In 2020, as part of Denmark's extensive, free-of-charge PCR-testing strategy, approximately 4 million individuals (69% of the population) underwent 10·6 million tests. Using these national PCR-test data from 2020, we estimated protection towards repeat infection with SARS-CoV-2. ⋯ None.
