FDA, Moderna’s mRNA RSV VACCINE Trial and SEVERE Side Effects

… Moderna halted its clinical trial

… experimental mRNA vaccines for respiratory syncytial virus (RSV) in babies

… higher rates of severe RSV illness among the vaccinated babies  [ FDA ]

… a formalin-inactivated RSV vaccine trialed in the 1960s

led to two toddler deaths

… 80% of vaccine recipients required hospitalization for severe RSV

… were attributed to vaccine-associated enhanced respiratory disease (VAERD)

… occurs when vaccination promotes immune responses

that exacerbate the disease caused by subsequent infection with the pathogen

the vaccine was meant to protect against

… The trials were halted in 1967, and clinical RSV vaccine research stalled until recently
