TARSILA Real-World Evidence Study

The overall objective of Tarsila Study is to estimate the real-world vaccine effectiveness of maternal RSVpreF immunization during pregnancy in Brazil against medically attended (inpatient and outpatient) respiratory syncytial virus-associated acute respiratory illness in infants. To achieve this, two multicenter, prospective, test-negative case-control studies will be conducted among infants with ARI: the TARSILA Inpatient Study, evaluating hospitalized infants and the TARSILA Outpatient Study, evaluating infants managed in outpatient settings.

STudy of Real World vaccinE Effectiveness of maTernal RSVpreF vaccinatiON Against Respiratory Syncytial Virus (RSV) in Hospitalised Infants in Australia (STREETON)

This Pfizer-sponsored real-world retrospective non-interventional study will be conducted within a research network comprised of independent hospitals across Australia using data collected during routine standard of care clinical encounters available in health records, supplemented with information from the official national immunisation registry, the Australian Immunisation Register. Additional data from accredited pathology laboratories will be included. There will be no active enrollment of study participants, no direct contact with study participants, and no collection of any primary data outside of the standard of care. This study will use a test negative design to evaluate real-world vaccine effectiveness of RSVpreF vaccination during pregnancy against RSV-associated outcomes in infants.
