The Food and Drug Administration (FDA) has granted Fast Track designation to mRNA-1345, an investigational single-dose mRNA vaccine against respiratory syncytial virus (RSV) in adults over 60 years of age.
mRNA-1345 is a vaccine candidate against RSV that utilizes the same lipid nanoparticle as Moderna’s authorized COVID-19 vaccine. The vaccine encodes for a prefusion F glycoprotein eliciting a superior neutralizing antibody response compared with the postfusion state.
The Company is evaluating the safety, reactogenicity, and immunogenicity of mRNA-1345 in healthy younger adults aged 18 to 49 years, women of child-bearing potential aged 18 to 40 years, healthy older adults aged 65 to 79 years, and RSV-seropositive children aged 12 to 59 months in an ongoing phase 1 study (ClinicalTrials.gov Identifier: NCT04528719).

Data from an interim analysis at 1 month postvaccination showed that the vaccine candidate elicited a geometric mean rise in neutralizing antibodies of at least 11-fold from baseline in younger adults.
“We are pursuing an mRNA RSV vaccine to protect the most vulnerable populations – young children and older adults,” said Stéphane Bancel, Chief Executive Officer of Moderna.Stéphane Bancel, CEO of Moderna. “The Fast Track designation for older adults underscores the urgent need for a vaccine against RSV.”
The FDA’s Fast Track designation allows for expedited review of therapies that are meant to treat serious or life-threatening conditions. Generally, the designation is granted to therapies that are expected to have an impact on factors such as survival and daily functioning.
