Co-administration of RSV, influenza vaccines found safe and effective in new study

The co-administration of bivalent respiratory syncytial virus (RSV) prefusion F protein−based vaccine (RSVpreF) and seasonal influenza vaccine was found to generate robust immune responses and was safe and well-tolerated in older adults, according to new research. “With the typical seasonality of both RSV and influenza, it is possible that RSVpreF vaccine may be given at the same time as seasonal influenza vaccine,” wrote study authors in the journal Clinical Infectious Diseases. “Co-administration of these 2 seasonal vaccines would eliminate the need for an additional visit to a healthcare provider for individuals receiving both vaccines; this would likely be convenient for patients and healthcare providers and, in turn, potentially increase vaccination rates.” To further understand whether the influenza vaccine and RSVpreF vaccine can be safely co-administered and whether co-administration affects immune responses, investigators conducted a phase 3 double-blind, placebo-controlled study in healthy adults aged ≥65 years in Australia. Participants were randomly assigned 1:1 to...
