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
